Use cases
Real agents in production. Scroll to explore.
Inbound lead drops, agent calls in 60s, qualifies in natural conversation, books on your calendar. Falls back to SMS or email if voice misses.
Triage tickets across SMS, email, and chat. Browse your docs, take refund actions, escalate to a human only when stakes go up. Every action logged.
Quote intake from voicemail, ACORD form parsing, carrier follow-up by email, post-bind endorsements. Audit trail keeps E&O happy.
Voice intake handles insurance verification, prior auth lookups, and appointment booking. Every interaction PHI-redacted, audit-logged, replay-able for compliance review.
Integration
A simple, elegant integration so you can ship new agent channels in minutes — voice, SMS, email, browser, and agent-to-agent handoff through one consistent API.
Read the docsimport { Agent } from "agent-messenger"; const sdr = new Agent("sdr"); sdr.on("call", async (caller) => { const lead = await sdr.qualify(caller); await sdr.handoff("closer", { context: lead }); });
