What Is Copyscape?
Copyscape searches the web for copies of a page or block of text and shows where matching content appears. The basic tool checks a URL, while Copyscape Premium adds pasted-text checks, batch searches and an API used by publishers and content platforms. Copysentry watches registered pages automatically, scanning weekly or daily and emailing site owners when new copies show up. It comes from Indigo Stream Technologies, which also makes Siteliner.
