What does your tool do?

It checks your submitted source for direct plagiarism by splitting up the piece into small, distinct fragments. Then, using the search engine's API (official method), we scour Google, Google Scholar abstracts, Bing, and Yahoo for appearance of these fragments then report the results to you across all these different sources.

Will it check the entire document or just part of it?

We scan your entire document. There is no trial or paid membership or registration required. Everything is 100% fully functional and 100% fully free.

Will you store my scan in your database?

No. Your submitted text fragments are only temporarily sent to the search engines for checking. They are then discarded.

What is your privacy policy?

We are required to forward your IP address to the search engines when you request a scan to be done. Your IP address is attached to every scan request's fragments as they're submitted. This is required information for the search engines to make sure no one is abusing their resources.

What do I do if someone's plagiarizing my content?

If you've found plagiarizers on the web, visit Google's DMCA page. You'll need this info for all 3 search engines. If you've found print plagiarism, visit the U.S. Copyright Office Web Site.

I scanned a student's paper and there were sentences that were plagiarized.

Plagiarism, like cheating, is handled as academic misconduct by most schools and universities. The severity of the plagiarism should be considered. For example, if there was a simple misrepresentation regarding a source, this might be dealt with differently than if there was, say, a fabrication of sources or multiple submissions from the same source.

Things we are working on.

07/20/2010: The Bingers (Bing) is throwing false plagiarized positives in certain situations. We're trying to find out why. For example, we tried to scan a sentence "You can buy Scentsy bars online" and Bing threw a false positive when the sentence was original. We also tried to substitute a different domain and it threw the same error. "You can buy Scentsy online" still threw out a false positive. We're still looking into it.
