The provider-neutral router and platform for voice AI agents
STT, LLM and TTS are selected per language based on an independent benchmark covering 89 models across 18 languages, with pre-response failover.
Design a call step by step, plug calendars, CRMs, your APIs and docs into any step, then run it with inbound, outbound and call-list support.
Draft agents are tested against simulated callers, including red-team scenarios that try to break the flow, before they go live.
Every live call is scored against checks you write in everyday language, for example reading back a date or never quoting a price.
