Inside the platform

Powerful enough for engineers, accessible enough for everyone else.

Six things you'll notice the moment you start building. Less knobs, more control — and every one of them ready for production.

Real time, every time

Replies fast enough to interrupt.

Your agent answers before the caller wonders if they're still on the line. Natural turn-taking, in well under a second.

  • Median response around 700 ms across regions
  • Built-in barge-in and graceful turn-taking
  • Edge routing keeps latency steady at peak scale

Sounds like a person

Conversations that feel human.

Pacing, fillers, empathy — your agent reads the room and adapts. Callers stop trying to reach a human because they think they already are.

  • Voices with natural pacing and intonation
  • Reads emotion and adjusts tone in real time
  • Handles interruptions without losing context
