Copyscape
Plagiarism checker and duplicate content detection software.
Copyscape is an online plagiarism detection service that checks whether content is original before it is published, covering both human-written and AI-generated text. It also helps identify copies of existing content elsewhere on the web, addressing concerns about duplicate content, content theft, and search engine rankings.
The service includes a free checker for web pages, Copyscape Premium with copy-paste originality checks, PDF and Word file uploads, Batch Search, a private index, case tracking, an API, and WordPress integration. Copysentry scans the web daily or weekly and sends email alerts when new copies are found. Copyscape Enterprise deploys the detection service on-premises or in a private cloud. Free tools include plagiarism warning banners and a comparison tool for two web pages or articles.
Copyscape is provided by Indigo Stream Technologies Ltd and is used across publishing, content marketing, SEO, education, research, and generative AI. It is available through a free web-page checker, a paid Premium service, an API, an enterprise deployment option, and Copysentry monitoring; specific plan structures and pricing are not detailed here.
