About
Copyleaks is an AI-powered content analysis platform that detects AI-generated text, plagiarism, and other forms of duplicated or unoriginal content. It addresses a growing problem for schools, publishers, and businesses: verifying whether writing, images, video, or source code is original, human-made, and compliant with copyright and organizational AI policies.
The platform combines an AI text detector covering major models such as ChatGPT, Gemini, DeepSeek, and Claude, a plagiarism checker that searches a large index of websites, academic journals, and internal documents, plus detectors for AI images, AI video, deepfakes, and a grammar checker. Copyleaks reports AI detection in more than 30 languages and plagiarism detection in over 100 languages. The company says its detectors achieve over 99% accuracy based on internal English-language testing, and it lists PCI DSS, SOC 2, SOC 3, and GDPR certifications. Customers range from universities to large enterprises, and integrations are available via API, learning management systems, browser extensions, WordPress, and Google Docs.
