Ship bulletproof AI voice agents 100x faster with simulation, evaluation and live monitoring.
Auto-generate test cases from your system prompt or define your own, then run hundreds of parallel simulated conversations with presets for accent, mood and goal.
Score every call against weighted, customisable criteria such as task completion, policy accuracy, sentiment, interruption handling and latency, with seven-day trend tracking.
Every production call is silently logged and scored in real time, with alerts routed to Slack, email, PagerDuty, Opsgenie, Linear or webhooks when something drifts.
Connect Vapi, Retell or ElevenLabs agents in under five minutes using an API key, or route custom agents through the provided number and API.

Test, monitor and improve the voice AI agents you already run
Run your agent against hundreds of realistic personas, accents, background noise and edge cases before a customer ever dials in.
Red-team callers attempt prompt injection, jailbreaks and social engineering to check your agent holds policy under pressure.
Every live call is scored as it lands on more than 500 metrics, with issues filed, alerts fired and traces attached.
Purpose-built audio models measure pronunciation, emotion, vocal stress, pace, interruptions and dead air, not just transcript quality.
