Top Online Plagiarism Checker Tools in 2020 (updated)
Plagiarism – an intimidating word for students, academics, artists, writers, and all other righteous professionals, who put effort into their oeuvres by expressing original ideas. What would you feel if you found out that your essential brainchild was stolen?
Plagiarism should be eradicated to make the world a place of honorable education and doubtless authenticity.
I've compiled a list of various 50 plagiarism checkers you can choose according to your needs and capabilities. Though some detectors have much higher rating than others, I decided to be unbiased and to mix them in the list not paying attention to their popularity. So let's start comparing them.
This service is one of the most popular ones among miscellaneous users, professionals, students, and practically everyone who writes regularly in their daily lives. Unsurprisingly, it has the organic traffic of 8 million. You can use it for free if you need to track minor writing mistakes, while you should pay for the premium features, which are capable of showing plagiarism, weak or uncertain language, incoherent sentence structure, misuse of quotation marks, misplaced words or phrases, inappropriate colloquialisms, etc. Although Grammarly is not always 100% precise, its overspecified algorithms and machine learning help to display impressive results. Its minor drawbacks are the detection limited to web pages and the absence of download reports. Top 5 countries that bring the most traffic to Grammarly are The United States, The United Kingdom, India, Canada, and Australia.
This plagiarism checker was generated by a team of young professionals, educational enthusiasts that keep pace with the times. Though it hasn’t achieved the deserved popularity because “elder plagiarism-scanning sharks” have been trying to engulf every bit of the educational market, it has already shown the impressive improvements of algorithms and decent results. It developed an API for LMS integration, having effectuated its Moodle plugin, which has been already tested by small universities and content companies. Free options entail: a daily detection of 300 words for registered users and a 14-day trial for the Moodle plugin. Though some users complain that 300 words a day is not enough, you can try to calculate the number of words you can check at a moderate rate and realize that its pricing system is fair. If you need to scan more extensive works, you can choose from the following options: Basic Package (a single submission = $7,95 or 10 submissions = $15,95); Monthly Package (100 submissions = $20, 95 or 300 submissions + API access = $30, 95); Yearly Package (1000 Submissions = $99,95 or 3000 Submissions + API access = $149.95). Only a single submission consists of 5000 words while multiple submissions entail 1000 words per each. All subscriptions encompass plagiarism analysis, checking all over the web, homoglyphs detection and sentence structure scanning, publications’ detection (over 25 000 books, journals, newspapers, and magazines), as well as the option to download and print your PDF report.
PlagiarismSearch also provides VIP Services, which include unlimited number of submissions in a certain time frame, as well as personal client manager, around-the-clock support, and private area for storing the reports. Monthly unlimited submissions cost $99,95 while yearly unlimited submissions come at a price of $499.95. VIP are beneficial to those who check larger works regularly. Besides the services, the website provides you with valuable plagiarism prevention and writing tips you can find in their blog articles. Its blog resembles a compelling online magazine, which is rare for plagiarism detectors. Last but not least, it regularly posts discount codes via its social media profiles.
Also available in Spanish and Polish versions:

It boasts of hundreds of advanced algorithms that helped to generate an elaborate similarity detection. With the organic traffic of almost 15 thousand users, it gives visually appealing and informative reports, provides, citations, references, and highlights. Its main strong points are cooperation with Moodle, adaptation of plagiarism detection to individual Google Docs, Chrome extension, organizable online dashboard, and all-inclusive report. 1 page includes 275 words and it gives you 5 bonus pages upon registration.
DupliChecker has incorporated an abundance of free tools, among which are: plagiarism checker, grammar checker, comparison search, spell checker, XML sitemap generator, site link analyzer, various checkers related to keywords and backlinks, Google index checker, and even Twitter card generator. Though this checker definitely has its users, its major disadvantage includes the annoying advertisements and redirects to Grammarly, which creates an impression that this is actually some Grammarly’s subdivision. If you don’t want to register with the site, you’ll only be able to check a written work once a day. 1 search equals 1000 words.
Though the interface could have been improved, its loyal users got used to the basic layout because they the services are truly beneficial. Its main advantages are: supporting more than 190 languages, Chrome and Firefox extensions, Moodle plugin, Android app, and easy plagiarism detection by file upload (you can easily access your Google Drive for this purpose), URL, or by directly inserting your text at the website. It also has its Grammar checker and Article Rewriter – the latter tool rewrote my article awkwardly: it was transformed into a mix of different words which hardly merged into coherent sentences. You won’t have an opportunity to use this checker for free all the time because the number of checks are confined. However, you can pay $35 to use it for 6 months without limitations.
This tool is mildly used, predominantly because it doesn’t allow you to check papers free of charge. Once you sign up, you need to purchase credits to continue. One document submission costs $8.95, 5 documents submissions come at a price of $18.95, unlimited monthly package costs $34.95, and unlimited yearly package costs $115.95. Thus, unlimited packages seem to be attractive, while one submission and inability to test the detector for free are apparent flaws its creators should consider to gain more eager users.
Another easy-to-use tool, which looks like “nothing special”, but if you’re a student living on a budget, the most alluring thing of this plagiarism detector for you will be its price: only 8 dollars per month for 50 checks – and it’s a Premium account, while the free version is weaker and is limited to the amount of visitors: it’s simply not accessible after it generates 7,200 reports. If you want to scan more papers, each additional analysis will cost you 25 cents. As it is asserted on their website, “This service has proudly been used over 20 million times.” Hopefully, the low price doesn’t influence the quality
This is a beta version of a plagiarism detector, mainly aimed to examine works for which you hold intellectual property. Its free version utilizes the Yahoo Boss API. The number of API requests is currently limited and the scanner doesn’t work 24/7. It also redirects you to www.clonewolf.com. Hence, we cannot recommend this tool for now.
The organic traffic of more than 9 million says almost everything about this cloud-based authenticity-seeking tool. Its business section is focused on media publishers, lawyers, bloggers, scientific journals and SEO agencies. Its education section is intended for individual students and teachers as well as schools and universities as separate educational entities. It has incorporated a few APIs for LMS, such as Moodle, Google Docs, and Microsoft Office. Copyleaks accepts various document formats and discerns miscellaneous languages. Of course, such a giant of the industry has its mobile app and MS Office extension. What are the particularities of using it? You need to create an account, otherwise it won’t allow plagiarism searches. After you register, you will obtain 10 free pages. The pricing plans are flexible as it allows you to slide and choose a number of scans. For the business purposes, the lowest price is $9,99 per month, which entails 25,000 words.
For education purposes, the cheapest option is $10,99 with the same amount of available words. It also has an attention-grabbing blog that contains articles on various plagiarism matters
The website presents the following statistics: 77,000 customers from 72 countries already chose this authenticity seeker. The users checked more than 9,300,000 written documents so far. It checks not only the exact coincidences but also indicates paraphrased excerpts, highlighting the findings in different colors. Each customer has access to their saved reports via private accounts. Though you can potentially scan texts in various languages, its creators emphasize that the algorithms were tailored predominantly for English writings.
You can test its possibilities for free only after signing up – then 1 page will be available. The pricing selections are as follows: light package (20 pages) for $5.99, standard package (50 pages) for $9.99, and premium package (150 pages) for $25.49.
The interface of this checker looks outdated. It also doesn’t provide many options. However, it may turn out to be beneficial if your only aim is to find plagiarism. Besides plagiarism detection, its new feature is a website check. You can also publish your article on the website as well as report plagiarism. The option “For authors” allows you to see whether someone stole your original content and posted it somewhere on the web: they may also notify you of the findings via email. The checker is free of charge but its main drawback is that it supports only Google and Yahoo (though many people find it enough).
It has both free and paid options. The free one is Basic which contains 30 searches daily and is valid throughout 14 days. Its Pro edition costs $39.95 and not for a month, but… for a lifetime! It means once you purchase it, you can use it without limitations. The PRO checker includes Lifetime Package License, Extended PDF Support, Cross Comparison of documents, and URL/Webpage Scan. It also emphasizes on its round-the-clock clients’ support
and free updates. Its lifetime Business edition costs $147.95. Besides giving you all Pro features, it provides Multi Machine License, Customization, and VIP support. They boast of their cooperation with globally recognized academic institutes, such as Duke University, Broadwater School, Hellenic Open University, Cairo University, Delta State University, Imperial College, King Saud University, Trinity College, and many others.
After you use a Free Trail (only 3 searches – one before signing up and two others after the registration), you can try one of its quite cheap packages. It offers Basic plan ($10 per month), Business plan ($20 per month), and Enterprise plan ($50 per month). Each plan allows you to check by sentence, it doesn’t entail recurring charges, it allows you to insert the text and upload the file, and it also enables multiple users to login into the same account. It generates plagiarism and grammar check reports, and its apparent flaw is that checking takes too long.
14. Quetext.com
Quetext is presented as Plagiarism Checker & Citation Assistant. Students often choose this anti-plagiarism software as it is entirely free. It almost magically provides you with unlimited usage: scan your written works to capacity. You have to create an account to use it without impediments. Moreover, it claimed on its Facebook page that it is better than Turnitin, even being free of charge.
Where's the catch? We haven’t investigated it for sure but, perhaps, its altruistic version functions not to the fullest. That’s why PlagScan employed DeepSearch technology, which costs $9.99 per month. Unlike the free option, it allows uploading various documents, checks 35 billion webpages, 20 million books, and 1 million journals. As the developers assert, “We’ve completely reimagined what plagiarism prevention technology can do with fine-tuned algorithms that dive deep into the internet, and millions of other sources. DeepSearch gives you the confidence and peace of mind that no other technology can match.” These words prove that the paid version is more accurate one.
Despite the the impressive organic traffic of 1,4 million users, it still cannot boast of the interface authenticity as it is flooded with Grammarly ads. Nevertheless, it checks swiftly and provides a report that is easy to download. Among its other useful tools, you can find Article Spinner, Keyword Position Checker, Grammar Checker, Spell Checker, Backlink Maker, SEO Score Checker, Reverse Image Search, Domain Authority Checker, Word Count Checker, etc. And voila, this is totally free of charge. Are there any traps and pitfalls?
Though the name for the plagiarism checker is somewhat mysterious, its domain rating and organic traffic show that it has its regular users, particularly from the US and India. Besides plagiarism scanner, its differentiating features are separate checkers of grammar, spelling, punctuation, and style, as well as translator (for over 50 languages) based on SMT technology. Other benefits include its mobile app adapted to all Android and IOS devices, integration with Microsoft Word & Outlook, usage examples with matching adjectives. The only drawback is that it doesn’t provide a report. WhiteSmoke cooperates with both individuals and companies, being able to tailor the services according to individual needs. Its multifunctionality helps it stand out. It practices the incorporation of up to 75% discounts for various operating systems, so you should be attentive to catch the cheapest price.
If you visit the site, it will encourage you to improve your writing right from the start: that’s what its main message conveys. It has quite favorable domain rating, which proves that its backlinks often work to the benefit. Its main audience, primarily consisting of students, comes from the USA and the UK, with the organic traffic of 21.1K users. Besides plagiarism-scanning services, it also offers grammar checker and expert tutoring on writing. Though it doesn’t demand subscription, being based on the principle Pay-as-you-go, it requires credits. Its pricing system is as follows: 1 Paper = $7.95 ; 3 Papers = $19.95, and 5 Papers = $29.95. 5,000 words are given per credit. WriteCheck is interrelated with Turnitin: it employs the same technology of authenticity detection.
Predominantly, it offers plagiarism detection, grammar and spelling checker, and an automated proofreader. The latter provides feedback and writing instruction on vocabulary usage, sentence length and variability, passive voice detection, inappropriate phrases, analysis of sentence beginnings, and readability statistics. It also has Vocabulary Builder that helps you enrich your lexicon and see words in various contexts. Its free option is limited while its premium account allows you to use the enhanced features for $14.95 per month and $95.40 per year. You can currently apply 50% discount.
The drawback: a free account contains advertisements of Grammarly.
19. scanmyessay.com
The software, also called Viper, scans your written work for plagiarism against more than 10 billion resources, including not only websites but also journals and books. You can easily download a plagiarism report and send it to your instructor or colleague, if needed. The tool isn’t based on the system of subscriptions or monthly/yearly payments as it offers pay-as-you-go pricing. It means you choose credits with particular word count according to your needs. For instance, 1 credit equals 1000 words and costs $4, while 50 credits equal 120000 words that cost $67. The drawback: it doesn’t detect direct citations.
Copyscape greets you right from the start with an interactive video about its services. Its free tool is limited to revealing duplicated or similar content of a particular web page of your site. One more favorable free offer is plagiarism warning banners. You can add a banner to your site by copying the HTML code: this way you will warn probable violators against plagiarizing your material. If you need an advanced plagiarism detection, you will have to purchase credits for Copyscape Premium: the amount may vary between $5.00 and $500.00 depending on your needs. As it has generated its own API, it’s more beneficial to buy credits for the whole organization or educational institution. One more elaborate feature is Copysentry, which is able to scan sources all over the web to detect the possible plagiarism of your pages.
Many of you would want to use it when discovering that it was developed by Turnitin experts. It has continued the good tradition of the efficient plagiarism checking software primarily aimed at individual scholars, devoted to their academic career, and research institutions. Thus, it focuses on plagiarism detection in large academic papers before publication. It compares miscellaneous manuscripts against a vast database, which encompasses over 60 billion web pages and 155 million content items. It offers only paid options in the form of credits or a quote. Individual Package that includes a single manuscript submission (25,000 words and below) costs $100; 3 Credit Package, which costs $300, allows to submit multiple research papers or one extensively written work consisting of 75,000 words maximum; if you need to check even greater volumes of works, which is typical of an organization, you must request a customized quote. iThenticate cooperates with such leading educational establishments as Duke University, Purdue University, University of Florida, and others.
At first, you will stay because of the pleasant interface. Will you stay at the website for the second time? Probably yes because its features are versatile and useful for both students, teachers and institutions. Its scoring system is divided into several parts: similarity score, plagiarism risk score, paraphrase score, improper citations score, as well as matches score. It technically shows various types of plagiarism you can be subjected to. For instance, a high score of paraphrasing indicates the disguised plagiarism. Its other advantages include multilingual detection (scans even documents written in several different languages) and online editor. The report highlights plagiarized parts in different colors: Red indicates the direct coincidence with other documents, Orange points to paraphrasing, Purple detects bad citations, while Green marks proper citations. In its section Resources you can find interactive guidelines on understanding plagiarism and writing in general. It also offers tutoring services for $45. Users from Indonesia, United States, and India prefer this plagiarism checker.
A user-friendly interface welcomes you to the website with not so moderate prices as of the detector we mentioned above. What is the differentiating feature of this plagiarism analyzer? It looks like the usual plagiarism checker but it is a trusted one. Its recognized capability lies in scanning through both online and offline databases. Another great advantage is its Editing Tool that can check the readability of your work, grammar, style, indicate overused, repeated and vague words, the presence of clichés, highlight inconsistency in a text, show your thesaurus and literary techniques that you used, among others. Prices of plagiarism checks: 10 checks = $10, 100 checks = $40, 500 checks = $120, 1000 checks = $200.

One more plagiarism detector that looks dependent from Grammarly. Besides plagiarism checker, it provides various tools, such as Reverse Image Search, Online Ping Website Tool, Keyword Position, Backlink checker/maker, SEO score checker, Google Page Rank checker, Metatag analyzer, and others. The majority of these tools, such as Page Size checker or Server Status checker, are insignificant. What can make you choose its plagiarism detector is that it is free of charge.

This is a free plagiarism detector by ThePensters. I doubt its maximum efficiency because I scanned my published article via this detector and it didn’t indicate its existence on the web, stating that the text I inserted was completely original. It should have indicated self-plagiarism. Hopefully, such flaws happen rarely. If you don’t register with the website, you’ll be able to avail of the similarity scanner 5 times a month. On the contrary, once you register, you can take advantage of its plagiarism check without any restriction. They claim that the detection takes several seconds. I tested it and it looks veritable. However, that’s quite suspicious when thousands of words are scanned in seconds. The question is, “Do they truly scan throughout an abundance of databases or just pretend to do it?”
