What is Retell AI?
Retell AI is a platform for building, testing and deploying AI voice agents that answer and place phone calls. The agents can qualify leads, book appointments, find their way through IVR menus and do warm transfers to human staff with a short brief for the person taking over.
CX teams build agents in a no-code studio, and developers can extend them through APIs, SDKs, webhooks and custom functions. The platform lets you choose among LLMs (OpenAI, Anthropic, Google or Retell's own Tell-1), text-to-speech providers and telephony (Twilio, Telnyx or your own SIP). It also offers batch outbound campaigns, branded caller ID, persistent contact memory, post-call analysis and AI quality assurance. Retell gives a response time of about 600 ms.
Retell is aimed at contact centers in healthcare, finance, insurance, logistics, retail and debt collection. Pricing is pay-as-you-go per minute with no contract, and an Enterprise plan adds compliance and support features.
