This tool attempts to detect copyright violations in articles. In search mode, it will check for similar content elsewhere on the web using Yahoo! BOSS, external links present in the text of the page, or Turnitin (provided by EranBot), depending on which options are selected. In comparison mode, the tool will skip the searching step and display a report comparing the article to the given webpage, like the Duplication Detector.
Running a full check can take up to a minute if other websites are slow or if the tool is under heavy use. Please be patient. If you get a timeout, wait a moment and refresh the page.
Specific websites can be skipped (for example, if they copy from Wikipedia) by being added to the excluded URL list.
