How to Choose Plagiarism Checker for Teachers: The Complete Guide 2019

Hello, I’m Nancy :)

I am a middle school teacher who deals with constant checking my students’ works like my other colleagues. Undoubtedly, it takes a lot of time to analyze and verify the uniqueness of their works. That is why more and more teachers tend to use different online plagiarism checkers. It is because of my willingness to make life easier for teachers I created this site.

The aim is to highlight different online plagiarism checkers which are distinguishable due to price, functions and other features. This review will help you choose the appropriate variant. Thank you for visiting my site!

Today more and more teachers rely on online plagiarism checkers to determine the legitimacy of student works. However these tools differ in quality of examination, available options, and price.

The free solutions are not suitable for constant use, as they’re usually worse at detecting plagiarism and have a number of limitations. The paid solutions seem to be all equally perfect, but in fact, examination shows that for the same price you can get vastly different results.

Best plagiarism checkers:

The table below lets you overview competitors’ capabilities and price at a glance.. The quality rate in the third column is based on a practical test, in which I challenged the tools with different duplicates. While some of the tools successfully passed the test, recognizing cheating and accurately tracing the original sources, others were not so precise. In brief, to get the highest accuracy at no cost, go for The Pensters. This free solution partially detected duplicates in some of the sample texts I submitted. In turn, Grammarly proved to be the most (the truly) accurate tool offering professional paid solutions.

1. Quetext – 1/5

Quetext is a simple plagiarism detection engine based on Natural Language Processing and Machine learning algorithms. Raising money on advertising, Quetext is free for users and doesn’t require registration.

The Quetext interface

Text length limits

Users can paste in text with less than 20,000 words.

Examination

Quetext compares documents to web sources. It doesn’t consider common phrases as cheating in order to prevent a false plagiarism detection. Quetext uses a patented machine-learning algorithm and doesn’t simply find exact matchings, but checks if they can actually be considered as plagiarism.

Quetext plagiarism report

Upon verification, Quetext generates a simple report that doesn’t show originality percentage, but highlights the matching parts of the text and provides users with the sources list.

Support

You can leave general inquiries or feedback via email. Didn’t get a reply for my questions when writing this article.

Pricing

Quetext offers a free version only.

2. The Pensters – 3/5

Build for students, The Pensters can be used by teachers too. Not for ordering academic writing works though, but rather for checking them. The integrated plagiarism detection tool can be used for free without any registration up to 5 times a month.

The Pensters dashboard

Text length limits

You should submit not less than 1000 symbols at a time.

Examination

The Pensters searches for similarities in multiple online sources, as well as its own database. The process takes a few seconds and once the results are ready, matching sentences are highlighted. As you can see from the picture, one of the phrases in quotation marks has been excluded. The report contains a list of sources with links, but cannot be downloaded.

The Pensters plagiarism report

While The Pensters flagged fully copied texts as unoriginal, a passage with character replacement got away with it. The fact that the tool excludes phrases in quotation marks increases the originality percentage in the final report, even if the text is identical to another on the web.

3. Small SEO Tools – 1/5

Small SEO Tools is a free service created to help SEO specialists avoid publishing duplicated content. However the test showed it doesn’t seem to resolve the issue.

The Small SEO Tools interface

Text length limits

You can submit up to 1000 words at a time.

Examination

You can either copy and paste your text or upload a DOCX or TXT file. No signing up is required to start using the service.

The website claims Small SEO Tools scans each sentence one by one against various search engines and marks every complete sentence that isn’t original. However upon checking a short text fully copied from Wikipedia, the tool identified it as 40% unique. The same text with character replacement appeared to be 100% unique and 80% unique when paraphrased. A passage from an online PDF hasn’t been detected either.

Small SEO Tools plagiarism report

Apart from being little reliable, Small SEO Tools can be irritating to work with. You will most likely need to prove your humanity with the reCAPTCHA system before every new search. Sometimes the website doesn’t verify submitted documents at all, while other times it doesn’t generate downloadable reports.

4. Search Engine Reports – 1/5

Search Engine Reports is pretty similar to the previous platform described. Just like Small SEO Tools, it doesn’t ask you to register nor pay, but the examination quality leaves much to be desired.

The Search Engine Reports interface

Text length limits

You can submit up to 1000 words at a time.

Examination

Once again the website’s promises and research results turned out to contradict. The service did detect plagiarism, but strangely enough the same document generated different results when checked twice (33% unique first time and 22% unique second time). Apparently, documents are only scanned against HTML resources, since a passage from an online PDF was marked as unique.

Search Engine Reports plagiarism report

Anyone who replaces letters can get away with it, seeing that the tool doesn’t recognize the trick. Paraphrasing can be a solution here too: changing a few words here and there rendered the text 90% unique.

There’s no report to download, but matching sources are provided with corresponding links. If you open them, you will see an original text and identical parts highlighted within it.

5. EduBirdie – 3/5

Plagiarism Checker by EduBirdie is a free web-based service specially designed to detect duplicate content in your text. For faster and more accurate results, it offers to choose the type of paper: essay, website content, resume, or other, fill in the title and paste or upload a document. Apart from checking the text for plagiarism, EduBirdie also provides a rewriting tool that is promised to make a submitted paper original in a few minutes.

The EduBirdie dashboard

Text length limits

Text must be under 19,900 characters in length.

Examination

The content you enter is compared against different databases and the entire internet. The algorithm provides a search for potential plagiarism among the papers of the chosen type and allows to find the coincidences on the basis of lexical frequencies, word-choice, and matching phrases.

EduBirdie plagiarism report

Once the search completes, the result appears along with the highlighted plagiarized parts, match percentage, and references to the original text.

Support

You can contact the technical support specialists via phone or email.

Pricing

The plagiarism checker is totally free and allows you to conduct as many searches as you like. However, if you want to use the rewriting service to make your paper plagiarism-free, you need to pay $9.99 at a time.

6. FreePlagiarismChecker.pro – 3/5

FreePlagiarismChecker.pro is a free simple plagiarism scanner that detects duplicate content in your text. It is created to help teachers, students, website owners, SEO specialists and anyone else who want to protect their writing from duplicate content and ensure that their texts are unique.

The FreePlagiarismChecker.pro dashboard

Text length limits

You can check up to 1,500 words per search.

Examination

The plagiarism checker uses various search engines when looking for duplicate content. It compares your text with other documents that are available on the internet. The service scans sentence by sentence in search for similarities and highlights the parts that are not original.

FreePlagiarismChecker.pro plagiarism report

Once a similarity check is performed and the duplicate content is found in the document, the engine automatically marks it with a yellow line. There’s no detailed report, but you can see the overall percentage of plagiarism and a list of links to the sources where duplications were detected. By clicking on the highlighted parts, you’ll see the duplicate sentences and phrases in the corresponding sources next to your text.

Support

I haven’t found any contacts to keep in touch with technical support.

7. Plagramme – 4/5

Plagramme is the brainchild of the idea to create a plagiarism checker that would be perfect with all languages, not just English. As a result, Plagramme is the best in small language detection and as good as the oldest and best known competitors. The service offers some exceptional scoring and highlighting options based on an advanced plagiarism detection algorithm.

The Plagramme dashboard

Text length limits

Plagramme has a minimum text length: the shortest document should contain at least 250 words.

The standard limit of 50 MB per document can be changed by customization. Both huge and small documents are checked with the same accuracy.

Examination

For examination, Plagramme uses their own database, as well as that of their partner. Overall, the continuously growing database now amounts to 14 trillion websites with more than 300 GB of materials.

Plagramme features an enhanced scoring system, whose capabilities go beyond simple detection of plagiarism percentage. For example, if a student’s paper contains one fully copied and 99 unique pages, then a standard similarity score would just amount to 1%. At the same time, Plagramme is able to refer such papers to the “Highest plagiarism risk” group, thus indicating that the document needs a deeper look.

Plagramme plagiarism report

It’s also worth mentioning that Plagramme defines plagiarism as similarities of big texts and therefore doesn’t mark simple words. This allows you to avoid a false positive for plagiarism, when in fact the paper is unique.

Support

Support is available inside the service and by email. The response time is from 2 minutes to 3 hours. In my independent testing, Plagramme demonstrated the promptest and at the same time qualified support service.

Pricing

Plagramme doesn’t charge for verification. Users are only asked to pay for detailed reports and additional features. The price depends on the document size and the plagiarism percentage and starts from $0.35. Plagramme grants free accounts for educators and discounted accounts for researchers.

8. PlagScan – 4/5

PlagScan leverages a unique two-step algorithm based on the latest research in computer linguistics. It boasts a number of robust features, which allow users to check several documents simultaneously, exclude some matching text from the report, compare documents to each other, get results by email, and more.

The PlagScan interface

Text length limits

Users can scan documents of up to 1,000 words and less than 300 kB at a time with the trial version.

Examination

Since comparing documents to all the other documents in the world is unpractical, PlagScan has developed an algorithm that searches for thematically related documents. In other words, the document’s subject determines the sources it’s compared to. The search is based on the Web and the PlagScan database. It’s also possible to create a custom library of documents, and check new text against it.

PlagScan's plagiarism report

PlagScan considers three consecutive words matching as plagiarism, making even a rewritten text with a different word order or synonyms prone to be revealed.. Upon verification, PlagScan generates a customizable report that can be viewed and edited in a browser and also downloaded. The MS Word version of the report contains interactive annotations for plagiarized phrases (this option is available for files with less than 100,000 words or 10 MB).

Support

You can send a message to the support team using the contact form on the website.

Pricing

PlagScan has different pricing policies for individuals and organizations. Private users don’t buy a subscription, but pay for credits: $5.99 for 6,500 words, $12.99 for 25,000 words, $24.99 for 62,500 words, and $49.99 for 150,000 words.

Organizations can acquire subscription plans at $19.99/month or more (paid annually), depending on the number of users and other factors.

PlagScan offers a free trial, allowing new users to check up to 2,000 words for free upon registration and email confirmation.

9. PaperRater – 2/5

Paperrater is another proofreading solution that combines grammar and plagiarism checking. Based on an Artificial Intelligence engine, it automatically analyzes and scores your text, and provides relevant feedback. Paperrater is a web-based service, which means that it doesn’t require any software to be downloaded and installed.

The Paperrater interface

Text length limits

Paperrater has a 96,000 character limit for every search (approximately 20 pages).

Examination

Instead of maintaining an internal database, Paperrater compares submitted text to over 10 billion documents on the Web. The detection doesn’t rely on past submissions: most papers are deleted from the website within hours after being uploaded.

Paperrater plagiarism report

Upon verification, Paperrater generates a simple report showing the originality percentage and the list of matching web pages for the whole text and for particular phrases.

Support

Responses are almost always given within one business day and usually within a few hours.

Pricing

PaperRater has both a free and a premium plan, however the plagiarism finder is a paid feature. The premium membership costs $14.95/month or $7.95/month (if paid $95.40 for a year) and involves improved performance.

10. Noplag – 3/5

Noplag is an online plagiarism detection service with a modern interface and a wide range of flexible options, such as citations & reference detection, simultaneous verification of multiple documents, report customization, and more. Apart from checking against the Web and its database, Noplag allows you to create a custom library of your own content, and check new documents against it for free.

The Noplag interface

Text length limits

Users cannot upload files with more than 100,000 characters for one check.

Examination

Noplag checks documents against the Web, as well as its own database that contains more than 5 million academic papers, journals, publications, articles, and more. Users can also upload their own files and check new documents against them for free.

Users can omit correct citations and references from the results, which is especially convenient for checking academic papers.

Support

Noplag provides email, phone and chat support.

Pricing

The price depends on the type of examination. You can choose to check your document against the Web ($0.1 per page), the Noplag Database ($0.04 per page), a publication ($0.05 per page), your personal library (free), or use all these options altogether. One page is considered to consist of roughly 200 words.

11. Copyscape – 3/5

Copyscape is made to protect content from being copied and stolen. It achieves this aim through a range of free and paid solutions, including Plagiarism Checker, Copysentry (which automatically monitors the web for copies of your content), Comparison Tool (which compares two articles or web pages), and others.

The Copyscape interface

Text length limits

Copyscape doesn’t place any limits on the text length, though it’s recommended to check under 2,000 words at a time. The free version provides a limited number of scans for a certain website per month.

Examination

In order to identify online matches, Copyscape doesn’t use its own database instead it relies on various search indexes. Simple reports don’t contain information on the plagiarism percentage, but display a list of the internet sources where matching phrases have been detected. Plus, Copyscape highlights identical text on the corresponding web pages, not within the verified document.

Copyscape plagiarism report

Support

All support is taken care of via email. The response time is from a few hours to 48 hours.

Pricing

Copyscape Premium requires search credits to be purchased. One search credit equals one web page or portion of text checked, and costs $0.05 with a minimum purchase of 100 credits ($5).

Grammarly is a perfect solution for educators and writers, as it combines an accurate plagiarism detection service with an automated proofreader.

Conclusion

A plagiarism checker is a relatively simple tool, but it has the big responsibility of discerning the (un)originality of academic works, website content, and other types of text. To choose the right software, it’s crucial to test its real capabilities beforehand. According to my independent examination, the most reliable paid solution is Grammarly, , which was accurate in detecting plagiarism and its sources in the sample documents. In turn, the best free tool turned to be The Pensters with the 3/5 score for the quality of examination

    Is there any ways to deceive plagiarism checkers?

    1. Nancy (author)

      Hi Jacky,

      There are many ways to fool plagiarism checker services. Students can change downloaded works on their own. For instance, they replace words, look for synonyms or even just delete unnecessary paragraphs according to them. They can use some references to other author’s works to prove their innocence of any plagiarism. Students may also use online dictionaries of synonyms, replace letters with foreign ones or combine multiple sentences into one. Besides, it is possible to plagiarize a paper written in a foreign language. If you translate it word for word, then you can successfully pass it off as your own. Furthermore, it’s easy to bypass free tools, unlike paid ones.

      Probably, the answer depends on the degree of a student’s resourcefulness. It’s well-known that your teachers can recognize your specific style without problems. So, students can easily be caught because of the sudden change of their usual style: usage of different figures of style or new sentence construction. Experienced teachers always note this.

    Hi!

    Thanks for a thorough comparison. I’m writing a scientific article for an academic journal and take some extracts from different resources. The requirements for the article include plagiarism percentage. Is there a plagiarism checker that will show me the the uniqueness before I send the article to the journal?

    Thanks!

      Hi Joe,

      Thanks for your question. I’m a huge advocate of Grammarly and highly recommend it to anyone who writes scientific papers. The plagiarism checker can detect plagiarism from billions web pages and ProQuest’s academic databases. Unlike many other similar tools, it allows you to check large documents of up to 40 MB in size. It’s a great advantage if you need, for example, to check a thesis. And what I like most, Grammarly works incredibly fast: it scans documents and generate reports in just a few seconds.

    Hi, Nancy!

    Thank you for information. It’s very helpful. I’m going to make two rewrites of the same text and I need them to be unique towards each other. Can you recommend a plagiarism checker for two documents?

      Hi Emily!

      I’m happy you find my article helpful. There are severals tools in my list which let you compare documents against one another. But I would advise you to use Copyspace: https://www.copyscape.com/compare.php.

      It’s quite simple, fast and free. You just need to enter any two web pages or articles to see how they match up.

    Excellent comparison! I’ve added it to my bookmarks. Now, I’m writing a thesis which is quite long and I need to verify its uniqueness. Is there a plagiarism checker for large documents?

    1. Nancy (author)

      I’ve already said that I’m a strong supporter of Grammarly. But if you need to check a document over 40 MB in size, you can use Unicheck.This tool is also quite reliable and allows you to upload 70 MB documents and check up to 100,000 words at a time.

    Thanks for the great article. Do you know if there are any plagiarism checkers that detect plagiarism based on how the user enters the text into an interface rather than though comparison with existing documents?

    1. Nancy (author)

      Hi Rachel! I’m sorry but I have never come across such tools

  7. Dr. Sims

    Thank you for your article! I’m a university professor and my duties include guiding students on research matters. I need not only to check their thesis, dissertations and other research papers for correspondence to the theme, in-depth research, and the proper structure, but also control that there’s no plagiarism. What tool can you recommend for plagiarism detection in my particular case?

    1. Nancy (author)

      Hi Dr. Sims! I’ve tried a lot of plagiarism checkers, but still Grammarly is number one for me. Firstly, it’s really a reliable tool that easily finds the coincidences and gives a reference to the original text. Secondly, it allows you to check long documents — up to 40 MB in size or up to 60 pages at a time. And what is also important in your case, Grammarly does check for plagiarism through the largest full-text database of books and academic texts, including scholarly journals, newspapers, reports, digitized historical primary sources, and ebooks from ProQuest.

    Hi Nancy! Very informative article, but, unfortunately, I couldn’t find the information about which tool to use for checking PDF files. I’ve already tried a couple of free checkers, but they work only with Word documents and TXT files. I would be very grateful if you could share your insights on how to detect plagiarism in PDF files.

    1. Nancy (author)

      Hi Mark! Thanks for your question. Free checkers typically have very limited options, but there’s a way out — you can copy the text from your PDF file and paste it in a special field of the checker, say Quetext or the Pensters.
      You can also use a more advanced tool that allows you to download a PDF file and help you track duplicate content. As for me, I like how PlagScan works with PDF documents. The upside is, you can check up to 2,000 words for free at a time with the trial version.
