One more plagiarism checker that works well from what we could test.

A metasearch engine, that uses smartly the input combined in various ways. The report can be downloaded either in pdf or word format.

Free if you mind not clicking on several ads lying around the buttons …

Disciplines: Education, Academic research, Publishing, Journalism, Content marketing.

Free alternative to Turnitin, Copyscape, Grammarly.
