Build on ECHO.

Everything you need to deploy, tune and measure your voice agent.

Introduction

ECHO is a voice-agent platform: deploy a human-sounding agent that answers every call, resolves most on the spot, and hands off the rest to a human with full context. No prompt engineering, no training data.

Everything runs over https://api.echo.ai. The CLI is the single source of truth: echo init, echo connect, echo deploy.

Quickstart

terminal
$ npm i -g echo
$ echo init
$ echo connect zendesk --kb support-docs
$ echo deploy
✓ agent live · 1.2s answer time · 92% resolved

The core commands, in the order you'll use them.

echo handoff <id>Escalate a live call to a human

The agent

An agent is a set of instructions plus a knowledge base: how it sounds, what it knows, and when it escalates. ECHO drafts all three from a sentence, then you review a few sample calls and ship.

Hand-off

Guardrails define when a call leaves the agent — tone, sensitivity, complexity, or a specific phrase. When a call crosses one, ECHO routes it to a human with the full transcript, intent and sentiment attached, so no one ever starts from zero.

Transcripts

Every call is transcribed in real time with intent, sentiment and resolution status. Search any conversation, replay the audio, and export the data to your warehouse.

Security & compliance

Call data is encrypted in transit and at rest, and access is scoped with SSO. We are SOC 2 Type II audited and never train on your data.
