§ Product · Voice · SMS · Webchat · 24/7
An AI agent that answers every call. And actually does the work.
It picks up on the first ring, talks like a person, qualifies the caller, books the appointment in your calendar, writes the lead into your CRM, and texts a follow-up — all before a human would have finished saying hello.

§ 01 / Inside a single call
From "hello" to booked in under a second of latency per turn.
Every call runs the same low-latency loop on the edge. Voice in, intent out, an action taken in a real system, voice back. Watch one turn travel the pipeline.
// live call lifecycle tracing
Voice in → transcribe → reason → act in a real system → speak back →
log and follow up. Tap any stage.
§ 02 / Connected to the systems you already run
The agent doesn't live in a silo. It reaches into your stack.
Built on MCP — the open tool-surface standard — so a new integration is a connector, not a rebuild. We wire the agent into your real systems with scoped, least-privilege access. The agent never holds a raw credential.
