Plagiarism Checker by Quetext

Free plagiarism checker: how it works, enter text into plagiarism detection tool.

We make it simple. Just copy and paste all content from your document into our plagiarism checker and hit the ‘Check Plagiarism’ button to get started.

Evaluate text for plagiarism

Our plagiarism detection tool uses DeepSearch™ Technology to identify any content throughout your document that might be plagiarized. We identify plagiarized content by running the text through three steps:

• 1.) Contextual Analysis
• 2.) Fuzzy Matching
• 3.) Conditional Scoring

Accurate plagiarism results

After evaluating the text against billions of internet sources, you will be provided with a plagiarism score showing the percentage of text that is an exact or near-match to existing text online.

Resolve plagiarism risk and use citations

Our ColorGrade™ feedback feature highlights exact matches vs. near-exact or “fuzzy” matches with corresponding colors. From there, you can resolve plagiarism issues by deleting or altering the at-risk copy. Or, you can use our handy “Cite Source” feature to generate citations in MLA, APA, and Chicago formats and insert the citations directly into your document.

Plagiarism Checker Benefits

Whether producing original content or verifying that of others, there’s a lot to gain from using a plagiarism checker. Accurate, automatic detection of duplicate content facilitates the copy-checking process for teachers, students, content writers, and more. Results showing the exact percentage of plagiarized content allows users to see exactly how much text has been copied and where they need to re-word.

For Teachers

Before homework can be graded for quality, it must first be confirmed as original. Our easy-to-use tool arms teachers with a simple, effective way to verify and grade students’ work. Educators at all levels can benefit from ensuring academic integrity through a comprehensive plagiarism check. From K-12, all the way through higher education, teachers are faced with the task of verifying the originality of the work of dozens, if not hundreds, of students each year. Automating this process frees teachers up to focus on the quality of work, rather than be bogged down by its originality.

For Students

While the prevalence of academic plagiarism is on the rise, much of it is arguably unintentional. A simple, yet accurate and comprehensive, plagiarism checker offers students peace of mind when submitting written content for grading. It is much easier to do a quick check for potential plagiarism before submission rather than convince a teacher after the fact that your academic integrity is not in question. And Quetext even takes checking for plagiarism a step further, helping students identify and cite the source itself with our built-in citation generator.

For Copywriters

Plagiarism risk is not restricted to academia. Anyone tasked with writing for an individual or business has an ethical and legal responsibility to produce original content. On top of that, content writers are often tasked with producing content on topics outside of their wheelhouse, leaving them reliant on the work of others for their research. Our plagiarism checker gives content writers a quick and easy method to prevent copyright infringement. Checking even lengthy pieces of writing takes only a few minutes, keeping companies’ public content in check and writers’ integrity intact.

Types of Plagiarism

It’s important to understand that plagiarism expands far beyond just copying someone else’s work word-for-word. There are several different types of plagiarism that should be avoided.

Self-Plagiarism

Many believe that, as long as they produced the work at some point in the past, they can include it in future pieces. However, even if you were the original author, that original work must be cited in order to not be flagged as plagiarism. Treat your past self as a totally separate author; be sure to include all relevant citations and quotations, the same as you would for any other source.

Patchwork Plagiarism

Patchwork plagiarism is the act of piecing together a "patchwork" of existing content to form something new. Assembling unoriginal content in this manner often involves some paraphrasing, with only slight changes. This type of plagiarism can be tricky and can certainly occur unintentionally, especially in academia. Since academic writing is largely based on the research of others, a well-meaning student can inadvertently end up plagiarizing.

Mosaic Plagiarism

Mosaic plagiarism is synonymous with patchwork plagiarism. It describes the process of loosely rearranging or restating another's work without issuing proper credit. It can occur accidentally or intentionally. For authors, mosaic plagiarism endangers their academic integrity or reputation as a writer. For those checking content originality, such as teachers, mosaic plagiarism can easily appear to be original content, which can make mosaic plagiarism especially difficult to detect manually.

Accidental Plagiarism

Plagiarism doesn’t have to be intentional to still be considered plagiarism — even in early academia, where students are just learning how to properly cite others’ work. While there may be no ill intent from the student, most schools have policies explicitly treating accidental plagiarism the same as intentional plagiarism. Students are expected to know how to properly issue credit to other authors. Similarly, content writers risk damage to their reputation if they produce plagiarized content, regardless of intent.

Plagiarism Checker FAQ

What is plagiarism.

Plagiarism is representing someone else’s work as your own. In educational contexts, there are differing definitions of plagiarism depending on the institution. Plagiarism is considered a violation of academic integrity and a breach of journalistic ethics.

What percentage of a paper can be plagiarized (or copied) and still be considered unique?

Generally speaking, similar or exact copies of another source should be kept under 15% for the total text of the article/paper/essay. As a best practice, citations should be used whenever using another source word-for-word.

What’s the difference between deliberate and accidental plagiarism?

Deliberate plagiarism is purposely copying works from books, articles, webpages, or someone else’s paper and representing it as your original work. Alternatively, accidental plagiarism occurs in a few different ways:

• Incorrectly citing another person’s works
• Failing to paraphrase another person’s works - even when citing it correctly
• Reusing your own previous papers and inadvertently representing it as a new idea

What are the consequences of plagiarism?

The consequences for plagiarizing another person’s works vary. But broadly speaking, the types of consequences can be grouped by person and profession.

Plagiarism consequences for students

Maintaining academic integrity is a top priority for every educational institution. As already mentioned, ignorance of how to properly cite sources is not an excuse for plagiarism. It is the student’s responsibility to ensure they are submitting work that has not been plagiarized.

Failure to do so can result in disciplinary action, including an automatic failed grade, removal from a class, or expulsion from a school or university. Students who are allowed to continue at their institution following an act of plagiarism may encounter mistrust and additional scrutiny from teachers and instructors.

Plagiarism consequences for copywriters

Copywriters stake their reputation (and by extension, that of their client or company) on their writing. All copywriters must produce completely original content for their clients.

The consequences for plagiarism here are clear: Copywriters who plagiarize the content of others will quickly find it difficult to obtain paying assignments. Similar to academic situations, it is the copywriter’s own responsibility to ensure that their content is 100% original.

Plagiarism consequences for journalists

Journalists are held to exceptionally high standards of integrity in their writing. A journalist who produces plagiarized content jeopardizes the trust of their readers and publishers. Plagiarism can instantly reduce a journalist’s career by a large margin. The ethical and legal standards issued to journalists are clear: Produce original, well-cited content or find another field.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

Testimonials.

First, I love Trinka. Congratulations on developing something that extensively aids editing, especially critical grammar conventions and word count reductions.

James Smith

Writing texts with correct English grammar and style is not an easy task for people who speak other languages. Sometimes you cannot find little mistakes in your document without help and moreover for academic writing. I tried Trinka AI as a tool of automatic correction and was quite glad with the suggested corrections and the feedback. With the feedback you understand why the suggested change must be taken into account.

Rosa Diaz Sandoval

I just wanted to say thank you for such a great and free service, all the other grammar checkers and writing assistants I have tried don’t have nearly the depth of features let alone all available on a free subscription. As a student with little income available I am extremely grateful that unlike all others companies you don’t limit features on the free plan. This is a fantastic product and given the income I would definitely upgrade to the premium. I've let all my fellow students know about Trinka as it is seriously a life saver.

Jesse Rumball-Smith

I have mainly used it to improve the language, grammar, and syntax of the scientific manuscripts that I write for national and international biomedical journals. I have found the interface to be user friendly and the procedure itself is efficient and hassle-free. The auto-edit is a great help and the supplementary page with the revision summary is an excellent idea.

Dr. Farooq Rathore

Trinka.ai is my most favorite choice for grammar and spelling edit. The application works correctly, is fast and tidily! Completely satisfied!

Georgieva Milena

The grammar checking tool exceeds Grammarly! I re-checked some documents that I had checked earlier with Grammarly. I was pleasantly surprised to see such a product from India!

Dinesh Gupta

Trinka has awesome features. Advance level of academic writing checker and suggestion are so original. I would highly recommend to others.

Aftab Hussain

I have tested Trinka and am impressed with its fine capabilities. It did better than the grammar checker I use. Well done! I have told my colleagues in my research lab to use Trinka. Hope it is widely used in academia.

Edith Davies

Trinka AI's suggested corrections and feedback astounded me. It is simple to use and extremely beneficial

Noor Al-rishi

It's been a wonderful experience using Trinka and I almost can't submit any manuscript without re-evaluating with it. In summary, Trinka has been a life-saver.

I enjoy using Trinka as a final spot check for my edited documents. It really helps find the few remaining errors that slip through during primary editing. I really like this platform. The thumbs down button is very useful.

Stumpf Curtis

I think Trinka.ai is a very interesting and potentially useful idea, especially for editors/publishers/journals. I found it very useful when I checked my editing work on the platform.

Dyke Gareth

I am happy with the overall performance. I have been using Grammarly for a long while, but when it comes to academic or technical writing, Trinka is definitely a much better option. Academic document settings and auto file edit are my favorite features.

Bhargava Sharma

Trinka has become my go-to tool for grammar corrections. The AI-powered corrections and language enhancements made writing a lot more easier. Now I am able to focus more on research than on writing an error-free document.

Ralph Bailey

The grammar correction and suggestion based on the AMA style guide is really impressive! Trinka is indeed the best grammar correction tool for medical writing.

10 Best Free Plagiarism Checkers in 2023 | Tested & Reviewed

Published on June 8, 2023 by Koen Driessen .

To find the best free plagiarism checker in 2023, we extensively tested and reviewed all popular tools to answer questions like, “How much plagiarism can they detect?” and “Are they actually free?”

Table of contents

Research methodology, general conclusions: free vs. paid checkers, 1. scribbr review, 2. quetext review, 3. duplichecker review, 4. small seo tools review, 5. pre post seo review, 6. grammarly review, 7. plagiarism detector review, 8. check-plagiarism.com review, 9. search engine reports review, 10. plagiarismchecker.co review, frequently asked questions about plagiarism checkers.

The plagiarism tools in this research are tested using 4 test documents , ranging from unedited to heavily edited.

Each test document consisted of plagiarized sections from 140 sources like Wikipedia articles, news articles, open-access journal articles, websites, theses and dissertations, and PDFs.

This setup allowed us to analyze:

• The reliability of plagiarism checker tools, even when texts are edited to varying degrees
• The depth and breadth of the tools’ content databases (whether they only covered websites or also journal articles)

Read more about the research methodology

We found that free tools were frequently misleading in their advertising and were lacking in many ways compared to paid ones. Our research led to these conclusions:

• Offers a limited free version
• Finds far more plagiarism than other tools
• Detects plagiarism even in edited texts
• Won’t store or sell your documents
• Money-back happiness guarantee, with live support available
• Self-Plagiarism Checker feature allows you to check for self-plagiarism
• You need to go premium to find out your precise similarity score and view the entire report

Scribbr offers a limited free version that’s perfect for checking if your paper contains potential plagiarism. To view the full report, you need to buy the premium version, which costs between $19.95 and $39.95 depending on the word count. There’s no word limit, so you can upload as big a document as you want.

Quality of matches

Scribbr’s checker, developed in partnership with Turnitin, heavily outperformed all free and paid tools in terms of the amount of plagiarism detected: 83% vs. an average of 42% across free tools.

It performed particularly well with source types relevant to students, such as journal articles and dissertations. Importantly, Scribbr was far more successful than other tools at detecting plagiarism in heavily edited texts, showing it has no trouble with paraphrasing plagiarism.

Scribbr could also consistently provide full matches instead of partial ones, matching the whole plagiarized passage to the correct source.

You see your results in a straightforward downloadable report. Different sources are highlighted in different colors, making it more readable.

The issues identified can be fixed with Scribbr’s Citation Generator , generating correctly formatted citations wherever they are needed.

In addition, Scribbr offers a Self-Plagiarism Checker . This unique tool allows users to upload their own unpublished documents in addition to the public database, to detect any possible self-plagiarism.

However, you can’t edit your text directly in the tool, and it’s not possible to re-check your document for free.

Trustworthiness

Scribbr will not store, sell, or share your uploaded documents. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Live customer support is offered in multiple languages to assist users. A guide and other resources explaining plagiarism issues are easily accessible.

Scribbr also has a happiness guarantee: if you’re not satisfied with the tool for any reason, you can ask for a new check or a refund.

Check out Scribbr

• Built-in citation assistant helps to add missing citations
• Documents not stored in database
• Support options available (but no live support)
• Finds partial matches
• Not clear how the free trial works
• Monthly subscription of at least $8.25 after free trial
• Not effective for scholarly sources
• Doesn’t detect all plagiarism

Quetext offers a free trial of 500 words, after which users must pay for a premium plan.

Additionally, uploading files to Quetext is a Pro feature. If you don’t pay, you’ll have to copy-paste the text from your document instead.

The paid version costs at least $8.25 per month (more expensive plans are available), which allows you to check up to 100,000 words.

Quetext detects more plagiarism (49% on average) than any free tool, but it’s unable to match each source text fully to a single source. Different sentences are attributed to different sources.

While Quetext claims to check against academic sources, we found it didn’t perform well at identifying plagiarism from sources such as journal articles and student dissertations.

Quetext’s plagiarism report is relatively straightforward to understand and provides a useful overview. A precise percentage is shown, with similarities in the text highlighted.

However, different sources are not highlighted in different colors, making the report somewhat difficult to read. Instead, orange highlighting is used for partial matches, red for full matches.

There’s also a built-in citation assistant that can help you fix plagiarism by adding citations. Unfortunately, it’s not very robust. Citations generated this way may not be accurate, and you have to add a lot of information manually.

Quetext states that it doesn’t save your text to a database and that all text submitted remains private and encrypted.

Information about the service is available in the form of FAQs on the website, and it’s also possible to contact the company by submitting a request form.

Check out Quetext

• Free (1,000 words per scan)
• Doesn’t save uploaded documents
• Relatively user-friendly reports
• Distracting ads for other services
• Low level of plagiarism detected
• Performs very poorly with edited text
• No color coding for different sources

DupliChecker’s service is free, though you can only upload 1,000 words at a time. If you go for one of their premium plans, you can go up to 25,000.

If you do want to upgrade, a large number of different premium plans are offered on the site, which can be somewhat confusing to navigate. The cheapest is $10 a month.

The level of plagiarism detected by DupliChecker was relatively low (44%).

While the tool was able to find some plagiarism, it was unable to find any full matches. Overall, it performed about as well as other checkers like Small SEO Tools.

DupliChecker’s website is unfortunately full of ads for their other services and for similar sites. A distracting animated “Make it unique” button appears in the report, advertising their rewriting tool.

In the online report, all plagiarized text is highlighted in one color, and it is difficult to figure out what source each source block is matched with.

The site claims not to save uploaded documents, and it deletes content after the check is complete to avoid data leakage. No live support is available, but there is a contact form on the website.

Check out DupliChecker

• Various options for document uploads
• Page is slow, somewhat confusing, and full of ads
• Scans individual sentences rather than full texts

Small SEO Tools is free to use, although you can only check 1,000 words at a time without paying.

You can run multiple checks if you need to scan more than that, although the site requires you to complete CAPTCHAs to upload multiple documents.

Small SEO Tools was unable to identify most plagiarism in our test documents, with an average of only 44%. Since it scans individual sentences separately, it was only ever able to produce partial matches.

Plagiarized text is highlighted (though all in one color), and you can click on it to be shown the source it was matched with.

The page is cluttered with a lot of ads that you can easily confuse with the buttons you need to press.

The report itself is relatively clear. While plagiarized text is highlighted in one color, the tool clearly links matched text with the source identified for it.

Small SEO Tools claims not to store your content after checking it. You don’t have to register to use the tool. Users can also contact a support email to request their personal data be erased.

Check out Small SEO Tools

• 1,000-word upload limit
• Color-coded highlighting
• Some full matches
• Citation assistant
• Live support option
• Detects a low proportion of plagiarism
• Report is hard to read
• Messy, ad-heavy page design
• Color coding doesn’t distinguish between different sources

It’s unclear whether Pre Post SEO is actually a free tool. While the website claims there’s a search query limit for visitors, the limit is not clearly specified and did not seem to apply when we tested our documents.

You can only scan up to 1,000 words per search and cannot see a complete list of matched sources (instead, you must check them manually). These limits are removed if you sign up for their premium plan, which costs $10 to $45 a month.

Pre Post SEO did find the occasional full match, but in most cases it was only able to find partial matches, like most free checkers. Overall, it performed about as well as tools like DupliChecker and Small SEO Tools.

The page where the checker is hosted is full of distracting and irrelevant ads, making the user experience frustrating.

A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool’s judgment was often wrong. Other than that, the same color was used for different sources, which made the report hard to read.

Pre Post SEO states that it does not store or sell your documents. There is a live support option on the site and a form you can use to request support.

Check out Pre Post SEO

• Language and citation assistant available
• Does not sell or share documents with third parties
• Finds a relatively low percentage of plagiarism
• Same colors used for different sources

Despite the way it’s advertised, Grammarly’s checker is not free. All you can do is see a screen that tells you there’s plagiarism in your text without giving you any details of where it is, how much of it there is, or what the sources are.

After this you’ll be directed to download the Grammarly app and subscribe to their premium service ($30 per month). There’s a limit of 100,000 characters (about 20,000 words) even after paying.

Grammarly was able to find more full matches than most free tools. However, it performed particularly poorly with academic sources and received a low percentage overall, scoring a total of 40%.

As a premium service, Grammarly has a clearer and more visually appealing style than most free checkers. The original formatting of the document remains mostly intact, but the tool uses the same color for all sources, making the results hard to parse.

The subscription also gets you a language and style tool and a citation assistant.

Grammarly does not store, sell, or share documents with third parties.

The site provides a support page with tips, tutorials, and FAQs, and you can submit a question via a form. Live support is not available.

Check out Grammarly

• Free to use (1,000-word limit)
• Does not store or sell your document
• Technical issues with long documents
• Difficult to match text with sources in the report
• Different sources highlighted in the same color

Plagiarism Detector is free to use and users do not need to register. However, there is a limit of 1,000 words per document. By paying, you can raise this limit to 25,000 words per document.

Plagiarism Detector’s performed about as well as other 100% free tools (40%).

The tool was mostly only able to find partial matches, attributing individual sentences to one or more sources.

Plagiarism Detector’s reports are somewhat difficult to read. The same colors are used for different sources, and hovering over a plagiarized section doesn’t show you the source. Instead, you need to find it in a separate list.

Plagiarism Detector states that it will not store or sell your documents. No live support is available, but there is a help request form.

Check out Plagiarism Detector

• Offers a citation generator
• Difficult to match text with sources in the downloadable report
• Scans sentence by sentence —rarely gets a full match

It’s unclear whether Check-plagiarism.com is actually free. The site describes the free upload limit in a confusing way, allowing you a certain number of “queries” (sentences) per month. However, these limits are not clearly specified and did not seem to apply when we tested our documents.

Check-plagiarism.com performed slightly worse than most 100% free tools, scoring a total of 39%.

While the tool was able to find some full matches, it mostly found partial matches.

The same color was used for different sources, which made the report hard to read. A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool was often wrong.

You can check up to 1,000 words at once for free. 

In the downloadable report, the format of the text is mostly retained. The report provides a long list of sources that are difficult to cross-reference with the text above.

The version of the report shown on the site itself is slightly better, as a box next to the plagiarized text allows you to see the text identified as the source. There is a “rewrite” function, along with a (manual) citation tool.

Check-plagiarism.com claims that the reports generated on their site are “highly secured and un-accessible.”

There are some FAQs listed on the site, but the answers provided are not very clear. They have live messaging support along with a contact form.

Check out Check-plagiarism.com

• Genuinely free for most purposes (1,000-word upload limit)
• Lots of distracting ads
• Unable to find most of the plagiarism
• Same highlight colors for different sources

Search Engine Reports is free to use, and users do not need to register. However, there is a limit of 1,000 words per scan. By paying, you can raise this limit to 30,000 words per scan.

The methodology this tool uses to find matches appears highly unreliable. It seems to simply search Google for each sentence in your document, counting it as plagiarism if it finds a match.

It identified only a low proportion of the plagiarism (38%) in our test documents. Due to its methodology, it was usually unable to find full matches, and it performed particularly poorly with scholarly sources such as dissertations and journal articles.

The report shown on the site gives a list of individual sentences marked as plagiarized or original. You can click a link next to each source, but all it does is google the sentence in question. The downloadable report highlights plagiarism within the text and shows a list of sources, but it doesn’t clearly link each sentence with a source.

There is also a language statistics function that lets you see words that appear frequently in the text to help limit repetition.

Search Engine Reports claims not to store any uploaded content in their database. There is no live support, but there is a contact form.

Check out Search Engine Reports

• Uploaded documents not stored/sold
• Detects a very low amount of plagiarism
• Misleading about costs—only free for five documents
• Low word limit of 800
• Lots of distracting ads and pop-ups

The tool claims it’s free, but it actually only allows you to upload five documents before requiring you to sign up for one of their many premium plans. These documents have an unusually low word limit of 800.

The premium plans offer options to increase (but not remove) this word limit. The cheapest is $15 per month, which only increases the limit to 1,000 words—a limit many other tools offer for free.

Plagiarismchecker.co gave some of the worst results out of all the checkers we tested, with an average of 30%. It was never able to provide a full match for a source text, only partial.

The tool is frustrating to use due to the high number of ads it displays and the low word limit.

The downloadable report sometimes didn’t include the plagiarism percentage, making it impossible to know how much of the text was plagiarized/original.

The report itself is difficult to read. All plagiarized text is highlighted in one color and is not clearly matched with the source identified for it.

The site claims that uploaded content is not stored in a database or shared with others. It also claims that “our advanced AI-powered algorithm ensures that your content must be protected under the copyright laws.” It’s not clear what this means.

While the site claims to have 24-hour support, there is no live support. There is a contact form on the site.

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

Run a free plagiarism check

If you’re a university representative, you can contact the sales department of Turnitin .

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages.
• 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

However, if you have cited the hard copy of a book and it also exists online, then this may be picked up by the plagiarism detector. If you have cited the source, you have no need to worry- it’s simply an extra precaution. Check out our blog post for more information about citing books .

What’s the difference between the BachelorPrint plagiarism detector and Turnitin?

The BachelorPrint plagiarism detector doesn’t save any uploaded work for data protection reasons, unlike Turnitin. Accordingly, we don’t rely on the same data base as Turnitin.

However, our plagiarism detector searches billions of publicly available sources on the World Wide Web.

Information : If the work is scanned for plagiarism in advance with Turnitin, and the university also uses Turnitin, there is a considerable potential risk for the writer. As Turnitin saves the uploaded work, this will then be in their database. If the university scans the same work on it, it will then be classified as complete plagiarism . We have already heard this a few times. The student’s work was therefore failed in the first instance and they had to prove that they had written the document saved by Turnitin.

I haven't received an email with the plagiarism report. What should I do?

It’s possible that the email has gone into your spam folder. In really rare cases, our email with the plagiarism report from the plagiarism detector might have been blocked by your email provider and hasn’t been received. Please contact us at [email protected] . We will email you the plagiarism report again.

Too few pages are shown in the plagiarism report.

For an overview, only text passages that might contain plagiarism are shown in the plagiarism report. The other pages where no plagiarism is suspected will not be shown. So less pages in your plagiarism report is really a good sign- it means that you’ve cited your sources correctly. Take a look at our blog article for more information about referencing and citation styles .

Why is a section marked as suspected plagiarism even though I have cited the source?

It’s possible that a section of text is marked as suspected plagiarism even though it has already been correctly cited, for example from a book. This happens if the software finds a further online source. In this case, the suspected plagiarism can be ignored and serves as extra peace of mind.

You can choose which format or which type you like and choose other specifics like removal options, how the results will be formatted, etc. Paste the text, confirm your settings, and you’re done. This is one of the content writing tools that will require a few seconds or even a minute to use.

Once done, you will get the list you need and the one you will like. Just paste it back to the original file, and you are done. Keep in mind that this has been one of the online writing tools for college students that is essential. If you have content with countless lists, it can save you hours and make sure there are no mistakes. These mistakes will occur now and then, and there is no way around them.

Free Online Plagiarism Checker with Percentage for Students

When students use online professional writing services, they expect to have original pieces written from scratch and according to their instructions. One of the most critical factors in using online writing services is that the pieces of writing they deliver to students are 0% plagiarism. Most writing companies check for plagiarism percentage but do not offer a free plagiarism checker online for a student to use when he asks, “check my paper for plagiarism.”

Sometimes students have written their essays and papers and want to use a plagiarism detector. They will not find an essay plagiarism checker to use on an online writing service – at least not the majority of them. When writing companies do offer additional resources, such as a free plagiarism checker, students come to trust that they are in the business of helping them rather than just making money. While knowing your plagiarism score is good, it is best to ask professionals " write my paper ," and there will be no plagiarism issues.

Plagiarism Checker for Students

Let’s face it. It’s easy to get a bit sloppy when doing research for a paper. An author’s words are paraphrased too closely to the real thing, a unique idea is not credited to its owner, and sometimes, even a direct quote is not cited correctly. All these things open a student up for charges of plagiarism, even if they write college papers from scratch with the best of intentions. Having a free online plagiarism checker for students, such as that offered by Trust My Paper, gives a student a neutral, objective source to ensure that no instructor will find plagiarized content in what he has submitted. And having a plagiarism detector that is a unique piece of software not used by anyone else is critical. More on that later.

There is also something called “self-plagiarism.” Most students are unaware of this issue, but it is accurate. Suppose a student has written a previous original piece and run through a common plagiarism detector used by many institutions. Now, he is writing a second piece on a similar topic and has decided to use a small percentage of content from that previous piece. Using that same common plagiarism detector will result in repeated content being flagged as plagiarized. Better to catch this with the Trust My Paper plagiarism checker before turning the paper in.

The consequences of plagiarism become more severe as students move through their schooling careers. A middle school student who writes his first research paper is a beginner and may not fully understand the “rules” of plagiarism. Rather than severe consequences, his teacher will probably re-teach those rules, point out what was plagiarized, and have him rewrite those parts. By high school, things get a little more serious, and students can face severely lowered grades on writing that contains plagiarism. Once in college, a student is expected to know the rules and to produce fully original work. Consequences for plagiarism are severe and can even include expulsion. If a student has any concerns about plagiarism, he must find an online plagiarism checking tool with percentage and clear his piece before submitting it. Trust My Paper has that tool.

Benefits of Free Online Plagiarism Checker by Trust My Paper

Let’s look at probably the most common online plagiarism detector – Turnitin. Most colleges use Turnitin campus-wide so that instructors will check papers for plagiarism through this software. And it’s a free plagiarism checker with percentage. Here is a typical scenario. A student finishes a paper and runs it through Turnitin. It gives him 95% originality, which is acceptable. He then submits that essay to his professor. That professor then runs it through Turnitin, and it comes back plagiarized. The student has some explaining to do, even though he did nothing wrong.

This is probably not your biggest worry when dealing with checking for plagiarism. You just want to ensure you have not goofed and plagiarized something by mistake. Often, these are failures to cite sources correctly or to paraphrase too closely. And if you use a good plagiarism checker with percentage, these issues will be identified so you can fix them.

You will not encounter undetected plagiarism issues when you use the free plagiarism checker on the Trust My Paper website. And there are some other significant benefits when you check a paper for plagiarism through our tool:

• We provide a 100% guarantee of the results
• We compare your piece with over 1,500,000 pieces of content on the web
• We support 150+ languages
• We use the latest, most sophisticated algorithms
• It’s super easy to use
• Shows originality in percentage

How Does Plagiarism Detection Work?

Once you have typed in Google “Trustmypaper.com check my paper for plagiarism,” you simply access it here, on the Trust My Paper website. The rest is self-explanatory:

• Enter the title of the piece/document.
• Paste/upload your piece.
• Check the box that you agree with the “terms and conditions” and then click the “check for plagiarism” box.
• Let the software do its work and provide you with a full report. That report will include the percentage of originality and point out any and all parts with similarities, along with the sources of those similarities.
• If you need to fix some things, you can run the piece through the checker again until you have the desired results.
• Once you have the results you want, you can download your report and turn it in with your work.

Once you have used it, you will believe ours is the best plagiarism checker you will find.

Advantages of Plagiarism Checker by Trust My Paper

Using Trust My Paper online plagiarism checker has several advantages that make it the preferred checker of most clients. These include the following:

• You get a full report that will let you fix any issues quickly and be confident that you can turn in your work without worry.
• You can check your paper for plagiarism as many times as necessary.
• Our free plagiarism checker is free, no matter how many times you want to use it.
• Your use of our plagiarism checker is confidential, and it is fast. You will get your report, usually within minutes, unless the piece is lengthy.
• Accuracy is guaranteed because we use the latest software and algorithms.
• You can drag and drop any type of file you have - .doc, .docx, .txt, .rtf, .pdf, .odt.
• Our checker is super simple to use. Once you try it, you’ll want to use it for every piece you write.

Can I check my essay for plagiarism for free online?

Yes, you can find an online plagiarism checker in a lot of places online. Quality can vary, though. Scanners that use the most current technology and algorithms will give you a good result. But there is no way to always know if those are in place when you choose a checker and to get the accuracy and completeness you really need. When you decide to use Trust My Paper’s plagiarism, you will get the accuracy and the comprehensiveness you need. You’ll have an overall percentage of originality and a highlighting of any text that is a problem.

As a student, is it free for me to use Trust My Paper plagiarism checker?

Absolutely. No matter what your grade level, no matter where your institution is located, you can access our plagiarism checker for free, as often as you need, 24 hours a day. It supports a number of foreign languages, is fast and easy, and will even scan a large number of sources to ensure accuracy. Our plagiarism checker is one of several free resources we offer to students because we are committed to your success. Helping you make sure your writing work is 100% plagiarism-free is important.

Can I scan my research paper for plagiarism for free?

Yes, of course. Our plagiarism checker will scan, analyze, and report on any piece of writing in any document format. Once the scan is complete, you can then download the full report or have it emailed to you, so you can attach it to your work when you turn it in.

Will your plagiarism report be the same as the one used by my university?

Online plagiarism checkers from different types of programs/scanners will not “look” exactly the same. But the information they all provide will be the same. There will be a percentage of originality, and for most instructors and institutions, it must be 90% or higher. It will point out pieces of content that are too similar to existing content, found on huge databases or elsewhere on the web. The “meat” of any plagiarism checker for students will be the same, just in different sequencing.

Can I be punished for plagiarism?

You bet you can. Younger students who are new to writing essays, papers, book reports, and such will not face the consequences. Their teachers will point out plagiarism and explain why it is wrong. As students get older, punishments will be in place for plagiarism. By the time students are in college, consequences can be mild to severe, depending upon the instructor and the institution’s policies. Our advice? Take no chances. Run everything you write through the Trust My Paper free checker, and submit your work with confidence.

What does a free plagiarism checker with percentage mean?

Many free plagiarism checkers only tell you if your content is original or not. That can be misleading. In truth, almost no content is 100% original. Commonly used phrases, quotes, and other similar content will count as content that isn’t completely original. Don’t forget about self-plagiarism! This is when a student uses their own previous work, but doesn’t cite it. In addition to this, different schools and organizations allow different thresholds of originality.

A free plagiarism checker with percentage doesn’t just showcase spots where there may be issues with originality. It shows you exactly how much of your paper is completely original. This lets you determine if you need to change anything.

All of these are clear reasons why you need a plagiarism checker that provides an accurate percentage. This will allow you to verify that your content is as original as it needs to be.

What percentage of plagiarism is considered bad?

That depends on the standards set by your instructor or school. It also depends on how you are presenting any information you have lifted from other sources. For example, a paragraph-long quote that is properly sourced and attributed is not plagiarism. However, it may show up as content that isn’t original. On the other hand, if you steal a shorter quote, and pass it off as your own thought, without giving credit, that is plagiarism.

In many cases, you can find out what the expectations are. Sometimes, your instructor will publish the percentage of originality they expect in the assignment rubric. In other cases, it will be with the course rules.

Don’t forget to learn what will happen if you should turn in a paper that isn’t completely original. In some cases, the consequences could be failure or expulsion. In other instances, your instructor may simply wish to review your paper to ensure that you have given proper credit.

I cited my sources, is it considered plagiarism?

In some instances, the answer is yes. For example, if you use someone’s exact words, but fail to use quotes, that may be considered to be plagiarism. You can avoid this by properly attributing words using quotes, in addition to citing your source. Sometimes, it is best to paraphrase or reword the statement.

Can you detect plagiarism without a plag checker?

There may be a few things you can do to look for plagiarism in your writing. For example, you can:

• Do a Google search on passages of your writing to see if it finds matching content.
• Double-check that all of your writing uses quotations and citations properly.
• Look for visual cues in your paper. For example, a passage that uses a different font may be something you copied in, then forgot to paraphrase or quote.

You may also ask someone you trust to review your paper.

Unfortunately, while these actions may help, none of them are a decent substitute for a reliable plagiarism detector. Remember that online, plagiarism detection software can quickly access and review more than a million papers, articles, and other content. You simply cannot match that using any other tool or technique. That is why it is best to rely on a high-quality plagiarism checker that gives you an originality percentage.

Is it safe to check for plagiarism online?

Absolutely! In fact, this is the safest, most convenient method there is. Did you know your instructor or employer will likely use an online checker to ensure your work is original? It only makes sense that you would gain peace of mind by having your writing double-checked for plagiarism by a company that is established in the field of academic writing. Here are some things to consider as you look for a plag checker online:

• Does the service have connections with reputable academic databases?
• Have students been satisfied with their experiences with this service?
• Is it easy to use the plagiarism checking tool?
• Does the company that offers the service have an excellent track record in the field of academic writing?
• Will the tool check for self-plagiarism?
• Can the student expect to receive an accurate number that reflects their originality?
• Is there multiple language support?
• Is it free?
• Can you use the plagiarism checker multiple times for a single paper?

Our plagiarism checker has all of these features. Further, you may drag and drop files, or use copy and paste. All standard file formats are supported.

Frequently asked questions

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

The Scribbr Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages
• 8 million publications from more than 1,700 publishers such as Springer, IEEE , Elsevier, Wiley-Blackwell, and Taylor & Francis

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

The free plagiarism report tells you if your writing contains potential plagiarism. The premium report gives you the resources you need to make your writing plagiarism-free.

Generating your (free or premium) plagiarism report takes between 1 and 10 minutes, depending on the document size.

In that time, your document is compared to the world’s largest content database, with over 99 billion webpages and 8 million publications.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.
