About this tool

The Duplication Detector compares normalized text from a Justapedia article and another source, then displays identical matching passages. It can also compare current articles with older Justapedia revisions.

Results are intended to assist manual copyright review. A result with few or no matching phrases does not by itself establish that copyright infringement has or has not occurred.
