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.
