The only AI detector I trust for production use. It catches GPT-4, Claude and Gemini output reliably and the plagiarism checker runs simultaneously in the same credit. The full site scan feature audited our entire blog in one session — invaluable.
Originality.ai correctly identified AI-generated content in a freelancer submission that our editors had approved without suspicion. The fact checker flagged a specific claim that turned out to be incorrect. These are features that matter for serious publishers.
The team dashboard is well designed for managing multiple editors reviewing content simultaneously. Credit consumption on large word counts adds up quickly — the Professional plan volume is the right level for high-frequency content operations.
