Copyleaks

Copyleaks is a content scanning platform that identifies plagiarism and AI-generated text within a single unified report through its AI Logic feature. The system compares submitted content against its own database of user-submitted documents, live web content, and academic sources to surface text similarities. For AI detection, it uses trained models capable of identifying content generated by tools such as ChatGPT, Claude, and other large language models. Scans can be submitted through the browser-based interface, a Google Docs add-on, a Chrome extension, or via the API for automated pipeline integration. The platform supports plagiarism detection in over 100 languages and AI detection in over 30 languages. See similar solutions. Copyleaks is used across education, publishing, marketing, and software development. Universities and training providers use it to verify academic submissions, while content teams use it to screen articles, blog posts, and web copy before publication. The Pro plan supports full website scanning by URL entry, which is useful for publishers monitoring for content duplication across domains. Developers integrate the real-time scanning API into content management systems and editorial platforms to automate quality checks at volume. The cross-language translation detection feature in the Pro plan identifies content that has been plagiarized and then translated into another language — an increasingly common evasion method Read our guide.
