Copyscape is a free plagiarism checker. The software lets you detect duplicate content and check if your text is original.
Copyscape is an online plagiarism detection service that helps you identify duplicate content across the web. It was launched on July 10, 2004, by Indigo Stream Technologies, Ltd.
With Copyscape, you can paste text or URLs into the search box to see where similar content appears online. The free version provides basic duplicate-content checks, while Copyscape Premium unlocks unlimited scans, file uploads, and API integration for seamless workflow automation.
Before becoming Copyscape, the underlying technology originated as an alerting service called “Google Alert,” which monitored the web for new appearances of specified text.
Copyscape is provided by Indigo Stream Technologies, Ltd., a private company co-founded in 2003 by Gideon Greenspan. The service was officially launched in mid-2004 to address the growing problem of online content theft.
