Platform for building AI voice agents that answer and make phone calls, billed per minute with no monthly minimum.
Overview
Retell AI is a developer-friendly platform for creating AI phone agents that can handle inbound support, appointment booking, lead qualification and outbound reminder or follow-up calls. Agents are built in a visual conversation flow editor or by prompt, connected to a phone number through Retell, Twilio or SIP, and given tools such as calendar booking, call transfer, knowledge base lookup and webhooks into your systems. Pricing is purely usage-based per minute with components for the language model, voice and telephony, which makes it cheap to experiment and predictable at low volume. A small business with some technical help typically builds a receptionist agent, tests it with a trial number, then forwards after-hours or overflow calls. It integrates with Twilio, Cal.com, Calendly, Google Calendar, Zapier, Make, n8n and HubSpot through tools and webhooks. A real caveat is that it is a building platform rather than a turnkey receptionist, so a non-technical owner will spend more setup time than with Goodcall or Rosie.
