After purchasing credits, which cost 10 cents each (minimum purchase of 50) users can then either paste in the text they want to check or upload a document (TXT, DOC, DOCX and ODT files only). Regarding the service itself, anyone who has used a plagiarism detection service should feel comfortable with PlagiarismDetect’s interface. The product is targeted primarily at students and teachers who want to check works for plagiarism but is also used by corporations, in particular publishers, webmasters and others to check for originality in documents. According to their about page, they are on version 3 of their service, which, according to them, is radically different from the earlier incarnations, having improved speed and accuracy. PlagiarismDetect is a plagiarism detection service that has been in operation since 2008. In the end, my experimentation with PlagiarismDetect painted the picture of a solid plagiarism checker with a somewhat unorthodox interface and an unfortunately high price point that may keep many people from using it. The results were interesting but somewhat inconclusive.

I was provided 200 free credits, $20 value, to test the service out and I used that to put PlagiarismDetect through a battery of tests, both to see how well it worked and how it stacked up against competitors. But with so many companies serving the major markets, PlagiarismDetect has an uphill battle trying to provide services that are compelling to users.Īt the company’s request, I decided to give PlagiarismDetect a try and see how I felt about it. is another online plagiarism checker that is trying to carve out a niche in the market. (Disclosure: I am a paid consultant for iThenticate, which is owned by Turnitin’s parent company, iParadigms.) There are also academic-oriented plagiarism checkers, such as PlagScan (Previous Coverage) and several ill-fated projects, all trying to take market and mindshare away from Turnitin.

Though CopyScape is still the best-established and best-known among webmasters, there is also Plagium ( Previous Coverage), PlagSpotter ( Previous Coverage) and Plagiarism.Pro ( Previous Coverage) to name a few.


The company’s cloud-based service for originality checking, online grading and peer review saves instructors time and provides rich feedback to students. Turnitin is the global leader in evaluating and improving student writing.
