## Copyleaks

Copyleaks has focused on content integrity since 2015, starting with plagiarism detection and expanding into AI detection and governance as generative models spread. Its core AI Detector analyzes text across more than 30 languages and can identify output from leading models such as ChatGPT, Gemini, Claude and DeepSeek, while its Plagiarism Checker searches a database covering 60 trillion websites, 16,000+ open-access journals and millions of internal documents to catch copying, paraphrasing and character manipulation. A unified multi-modal layer adds detection for video, audio and images, aiming to replace fragmented single-purpose tools.

For organizations, Copyleaks goes beyond individual checks with a scalable API that plugs content analysis into existing workflows, LMS platforms and publishing pipelines. Its compliance and governance use cases map to academic integrity, generative AI governance, code governance, IP and copyright protection, and detection of unauthorized LLM usage. Reporting dashboards, integrations and role-based controls help teams act on results at scale.

Founded as a plagiarism tool, Copyleaks now serves both individuals and large institutions. Free web tools give students and writers quick access to the AI Detector and Plagiarism Checker, while paid enterprise plans provide higher volumes, richer reporting and dedicated support. The company reports 100+ countries, 500+ enterprise and education customers and tens of millions of monthly scans.
