Website checkers
If you are looking for a plagiarism scanner to check your website against other sites (i.e. to see if anyone has copied your content) we recommend:
- Copy Leaks – currently free – just drop in your URL and you get a fairly fast report listing any matching sources. Click a source and you’ll see the highlighted content. Easy to use.
- Copy Scape – currently free with a premium option – drop in your URL and up pops a report with matching sources. Click a source to see the highlighted content.
Copyscape’s report is more comprehensive than Copy Leaks and in our testing, we found that Copy Scape discovered a lot more results.

Plagium (3/6)
Review of Plagium plagiarism software Verdict: There are lots of reasons not to purchase a subscription to Plagium.com: its website is unstable, its pricing structure and search functions are confusing and, most importantly, it’s not as good as detecting plagiarism as some free online checkers – give it a miss!

Plagiarism-Detect.com (3/6)
Verdict: 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.

PassProof plagiarism scanner – plagiarism checker software
Verdict: On the whole, £2.99 for one go of their scanner wouldn’t be good value for money … even if it was working, so it’s probably quicker and easier to give up and move on. Service: www.passproof.com/plagiarism_check/ What are the subscription options? e.g. free, paid only, paid and free. If paid options, what length … Read more
PaperRater.com (1/6)
Verdict: 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. Service: www.paperrater.com/ What are the subscription options? e.g. free, paid only, paid and free. If paid options, what length of subscription/price structure is offered? Free online … Read more
