We recently launched the Google plagiarism checker. Our viewers have asked us to make one for Yahoo. Since the fundamental coding is same we wrote one for yahoo / bing. Remember yahoo search engine is powered by Microsoft / bing search engine. So the results don't make much difference. Yahoo plagiarism checker searches yahoo results to find any pages that uses your content. Even if your own site uses this content it will show as duplicate.
