Free plagiarism checkers

We’ve reviewed 11 free plagiarism checkers for everything from accuracy to ease of use, and here’s the verdict.  Below you’ll see a quick summary of what we found – click the link to see our full review for the checker.

1. www.searchenginereports.net/articlecheck.aspx – Despite its simple, unfussy design and the offer of producing “fast and free’ reports, the website simply doesn’t work.
2. www.plagiarism-checker.com – Copying and pasting text into the scanner is the same as copying and pasting text directly into a search engine.
3. www.articlechecker.com – Not only is articlechecker.com totally ineffective, it’s also misleading. Avoid it at all costs!
4. www.smallseotools.com/plagiarism-checker/ – Flagged plagiarism in four of the six test documents.  Performed best when scanning large passages of plagiarised text which had been unchanged.
5. www.duplichecker.com/ – Despite its glowing testimonials, Duplichecker only detected plagiarism in three out of the six tests conducted.
6. www.paperrater.com/ – Despite the user-friendly feel of the website, it perhaps tries to do too much and, in doing so, doesn’t succeed in doing anything with complete accuracy.
7. www.plagiarism-detect.com/ – Although scoring around average amongst its contemporaries, the warning from its homepage, the unreliability of its document upload facility and the basicness of its overall design means it’s a website many will want to avoid.
8. www.activehistory.co.uk/plagiarizr/ – Fares less well than most of the online scanners available.
9. www.tuition.com.hk/plagiarism-checker.htm – The scanner was used to test six sample documents and it detected plagiarism in three instances.
10. www.plagiarismcheck.org/ – While Plagiarismcheck.org recognises the largest number of document types, it’s all theoretical because the scanner didn’t work.
11. www.plagiarism-detector.com/ – During tests, the scanner detected plagiarism in only two out of the six sample documents.
