Our verdict

Cleanlab watches an AI agent's output in real time and flags hallucinations, retrieval errors, documentation gaps and policy violations before they reach a user. When something is caught, a human-in-the-loop workflow lets non-technical staff fix the response or its underlying source. It still depends on a human to review and remediate flagged issues, so it does not fully remove people from the process.
