Advego Plagiatus - a software that searches any text that You enter for being already distributed on the Internet.

It actually searches for the same text on the Internet, or even the original text, that the input was rewritten from. This tool can help define if a text that is claimed to be original is actually was written by a copyrighter. The software is free.

It is still doubtfull, though, if the checking algorythm anyhow mathes the algorythm used in search engines for determine original or matchnig texts.
