Copyleaks is a content authenticity platform that checks whether text was written by AI and whether it copies existing sources. Its product line includes an AI text detector, an AI image detector, an AI video detector, a plagiarism checker, a grammar checker and text moderation. The company reports over 99 percent accuracy on internal English datasets, AI detection in more than 30 languages, and plagiarism detection in more than 100 languages. It also catches evasion such as paraphrasing, character manipulation and image-based plagiarism.
Schools and universities use it to uphold academic integrity without penalizing learning, and an LMS integration is available for that audience. Publishers and editorial teams use it to protect intellectual property and copyright compliance, while enterprises apply it for generative AI governance. Software teams can run source code verification to avoid unlicensed reuse, and AI developers can screen training data for synthetic content. Students can start for free.
Typical scenarios include an instructor scanning submissions inside the learning management system, a newsroom checking freelance copy before it runs, a company auditing documents for undisclosed AI use, and a compliance team looking for unauthorized reuse of its content by language models. The API lets businesses automate these checks inside their own workflow. The search index spans 60 trillion websites and search engines, over 16,000 open-access journals, more than a million internal documents and 20 code repositories, and the company lists PCI DSS, SOC 2, SOC 3 and GDPR certifications.
