Retell AI

Retell AI builds voice, chat, and SMS agents that answer questions, complete tasks, route calls, and hand off to people.

Retell AI

Retell AI lets teams build, test, deploy, and monitor AI agents for phone calls, web chat, and SMS. Agents can use knowledge bases, navigate IVR systems, book appointments, run outbound campaigns, connect to CRMs, and transfer callers with context.

It offers a no-code dashboard and an API for custom workflows. Pricing is usage-based rather than seat-based: voice agents cost per minute, chat agents per message, and add-ons such as knowledge bases, phone numbers, concurrency, QA, and PII removal can cost extra.

Features

  • Build visual conversation flows with functions, integrations, transfers, DTMF, SMS, and custom logic
  • Run simulation tests and convert production calls into regression tests
  • Deploy agents for inbound calls, outbound campaigns, web, chat, and SMS
  • Use knowledge bases to answer questions from synced business content
  • Navigate IVR menus and enter digits or extensions during calls
  • Monitor live calls and take over when human intervention is needed
  • Analyze calls with transcripts, post-call metrics, custom analytics, and AI QA
  • Access webhooks and API controls for custom communication workflows

Use cases

  • Answer customer-service questions across voice, chat, and SMS
  • Book appointments and manage scheduling calls
  • Qualify leads through inbound or outbound conversations
  • Route callers and perform warm transfers to human agents
  • Dispatch field-service requests and manage after-hours calls
  • Run surveys, debt-collection calls, and outbound campaigns
