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.

Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
