Copyleaks

Copyleaks stands out for its deep integration with learning management systems (Canvas, Blackboard, Moodle) and its support for over 100 languages, including cross-language plagiarism detection via translation. The AI content detector specifically targets models like GPT-4 and Claude, with a claimed 99%+ accuracy. However, the lowest paid plan caps at 25,000 words/month, which may be limiting for heavy users. There's no free tier, only a trial. The platform also offers a Chrome extension and Microsoft Office add-in for real-time checks. For businesses, the Enterprise tier provides custom training and white-labeling, but pricing is opaque. Compared to Turnitin, Copyleaks offers broader language support and AI detection, but Turnitin's database of student papers is more extensive. For casual users, Grammarly's plagiarism checker or Quetext may be more affordable.
