Docs detective is a plagirism detection service that scans documents that are in Google Docs for plagiarism.
There are two steps involved in the plagiarism detection process.
Docs Detective does all the heavy lifting by scanning the web for similar phrases, grouping text and documents, and organizing the results.
Docs Detective makes it easy to check documents in Google Docs for plagiarism. To submit a document click the Scan Document button which will open a dialog box where you can select a document to scan. Double clicking the document will start the scan. If the document you want to scan does not appear in the list of documents open Google Docs and verify that the document is type Document.
After a moment the document will appear in the Needs Review section and a progress bar will show status of the scan. When the scan is complete, the results are ready for review. A three page document with mostly original text takes about a minute to scan.
Documents can be scanned again after they have been revised.
If a document contains all original text it will show up in the Needs Review list. Clicking the green Mark as Reviewed text will move the document out of the Needs Review list.

Results may contain multiple sections of text, each of which match web documents. In this case the document contains two sections.
