Plagiarism checker tools are services that help you figure out if some text or a document has been copied from elsewhere. These tools are widely used by those who strive for unique content: for example, website owners, bloggers, and teachers. When a text is distributed without its author’s permission, it’s an infringement of copyright laws, and that’s why it is important to use trustworthy plagiarism checkers. There are many services of this kind available, however we only searched for free online plagiarism checker tools that don’t require an account. Take a look at what we found out from our research.

Plagiarisma.net
This online tool has limitations when you use it without an account – it only uses Yahoo for the search and shows only one domain for the duplicated text. However, it shows the percentage of the text that is unique, and if you click the plagiarised text, you’ll be redirected to a Yahoo search. A nice feature of this plagiarism checker is that you can create a PDF file with the results. This website also offers a desktop plagiarism checker for your PC.

Online plagiarism checker tools we didn’t include:
Plagiarism Software Plagiarism Checker – without an account you can only do a single search per month.
Plagiarism detect – it took forever to load the entered text, and then it turned out the timeout of captcha validation was over so we had to resubmit the captcha again and again and still got nothing.
NOPLAG – this online plagiarism checker has a limit of two searches per day as stated in their terms, however we could only do one. Also, two out of the three searched sentences were marked as plagiarised; the third one was marked as unique, but we used text from an article on our blog.
Paper Rater – when we entered the text, it sort of worked using this service, but the end page of this plagiarism checker was misleading and didn’t provide any information about the text.
Plagium – Plagium didn’t find the text of our blog’s article when we searched the web with the Quick Search mode. The Deep Search mode requires an account.
Free Plagiarism Checker by The Pensters – this plagiarism checker has a 1000-symbol minimum limit, so it simply won’t work if you need to search for a smaller text.
Search Engine Report – the buttons to upload the file and to initiate the plagiarism checker were disabled so we couldn’t use this service at all.
Free Plagiarism Detector Quetext – the first check was successful, but all the later ones were marked as 100% unique, although we used text from our blog’s old articles.
Dustball The Plagiarism Checker – the first time we tried to check the text from our blog, this service said that the text was 100% unique. A bit later we returned to check some other text to make sure that this service is useless, and we stumbled upon a message that our daily free limit (which equals one) was reached.
Free Plagiarism Checker Tool – a piece of text we copied from our blog’s old article turned out to be completely unique.
Plag Tracker – the first search was successful, then for the second search we were asked to provide an email address so that the results could be sent over. When trying to find out what the limitation of the free version of this service was, we came to their support service where tons of both free and premium users were saying that this service doesn’t work at all.
There are plenty of online free plagiarism checker services, however barely half of them are worthy of using. Save yourself time by using a free plagiarism checker from our whitelist above. If Google Search is not sufficient for you, you can check our review of Google Search alternatives.
