There are many other plagiarism detection tools available online but not all are trustworthy. Be sure to consider who your audience is (faculty and/or students), how the tools search (web search or comparing to a bank of papers), what the sites do with the papers you check, and if you want other grammatical/writing resources as part of the software you choose.
