If you are a free user, you’ll want to use PlagSpotter. PlagSpotter’s results, though slower, are better than Copyscape’s in that case because Copyscape’s free results are limited. Jonathan Bailey, Editor

Once you receive the duplicate content report, see a comprehensive list of URLs that contain your matched content as well as see where the matched content is located.

On the duplicate content report page, see a detailed, sentence-by-sentence view of how much text content is duplicated on your page, and how many external sites contain each specific excerpt of your copied text.

PlagSpotter allows you to automatically monitor your selected URLs for duplicate content. We will scan your content on a daily or weekly basis, detect plagiarism and notify you by email of the % of duplication.

Embed the "Protected by PlagSpotter" badge on your site to warn potential plagiarists from stealing your content. If someone steals your content, take measures to remove it from unwanted sites using our recommendations.
