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. 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. See similar solutions. 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. Copyleaks offers a meaningful combination of traditional plagiarism detection and modern AI content identification, which positions it well for organizations managing both concerns simultaneously. The Personal plan at $13.99 per month provides 100 scan credits covering up to 25,000 words monthly, while the Pro plan at $74.99 per month increases this to 1,000 credits and 250,000 words with added features including website scanning, an analytics dashboard, and priority support. The pricing gap between Personal and Pro is significant for small teams, and the free tier is limited in practical scan volume, which can make it difficult to evaluate the tool's accuracy before committing to a subscription Read our guide.
