Copyscape

The Copyscape Premium plugin lets you check if a WordPress post is original before it’s published, by using the Copyscape Premium API to check for duplicate content on the web.
The plugin will add a ‘Copyscape Check’ button to your WordPress interface, allowing you to check your posts whenever you wish. You may also set the plugin to automatically check your posts when you click ‘Publish’ and/or ‘Update’.
When duplicate content is found, a report of matching pages is shown. You may also see a detailed comparison that highlights your content on the found page.
