Free trialPlatform for building and running AI phone agents for call centers
What is Retell AI?
Retell AI is a platform for building voice agents that answer and place phone calls, with pay-per-minute pricing. Developers and contact centers use it for receptionists, appointment booking, customer support lines and outbound reminders.
Agents are built in a visual flow builder or through the API, with a choice of language models and voices. Retell handles telephony, interruptions and turn-taking, and connects to CRMs, calendars and custom functions so agents can look up data or book slots during the call.
Built-in testing, call analytics and post-call summaries help teams improve agents. New accounts get free credits, after which usage is billed per minute.
