Plagiarisma is a free tool that teachers and students can use to detect possible cases of plagiarism.
There are a few ways that you can use Plagiarisma. The easiest way to use Plagiarisma is to copy and paste a chunk of text into the Plagiarisma search box. You can also upload documents (RTF, Doc, PDF, HTML, ODT) to be scanned by Plagiarisma. The third option is to type a url into the search box to have Plagiarisma scan for possible cases of plagiarism. Whichever option you use, Plagiarisma will return a list of urls containing possible plagiarism matches.

Plagiarism isn't always intentional on the part of students. Sometimes they honestly don't realize that they're doing it. Having students use Plagiarisma to scan their documents before submitting them for a grade, could help them identify flaws in their works and change them before it's too late.
