About Confident AI

Confident AI surfaces failures in AI agents and automatically turns problematic traces into the the next eval, so teams don't ship the same issue twice. Unlike a general purpose AI observability tool, Confident AI has specialized evals for each AI system including multi-agent systems, voice, MCP, and more. For enterprises, Confident AI's an all-in-one AI quality platform including red teaming and AI governance.
