Prefactor is an agent evaluation platform for teams building AI agents: it observes every agent run from development to production, evaluates whether the agent did its job, and shows how to improve it.
Prefactor helps teams measure how agents perform (quality, groundedness, cost and latency), monitor them live, and improve them, with runtime controls to act on what it finds.
