This tool attempts to detect copyright violations in articles. Simply give the title of the page or ID of the revision you want to check and hit Submit. The tool will search for similar content elsewhere on the web using Yahoo! BOSS and then display a report if a match is found. If you give a URL, it will skip the search engine step and directly display a report comparing the article to that particular webpage, like the Duplication Detector.

Specific websites can be excluded from the check (for example, if their content is in the public domain) by being added to the excluded URL list.

Note: The tool is still in beta. You are completely welcome to use it and provide feedback, but be aware that it may produce strange or broken results.

% if result.violation:

${query.page.title | h} is a suspected violation of ${result.url | urlstrip, h}.

% else:

No violations detected in ${query.page.title | h}.

% endif

Best match: ${result.url | urlstrip, h}.
No matches found.
${round(result.confidence * 100, 1)}% confidence of a violation.
Results are cached To save time (and money), this tool will retain the results of checks for up to 72 hours. This includes the URL of the "violated" source, but neither its content nor the content of the article. Future checks on the same page (assuming it remains unchanged) will not involve additional search queries, but a fresh comparison against the source URL will be made. If the page is modified, a new check will be run. from ${result.cache_time} (${result.cache_age} ago). Bypass the cache.
Results generated in ${round(result.time, 3)} seconds using ${result.queries} queries.
