Retell AI

Retell AI lets teams build, test, deploy, and manage voice agents for phone calls, web, and SMS. A drag-and-drop canvas supports call flows, integrations, transfers, DTMF, and custom logic, with tools to simulate scenarios and test production calls.

Agents can handle appointment booking, lead qualification, customer service, IVR navigation, and outbound campaigns. The platform also offers live call monitoring and handoffs to human agents, CRM integrations, post-call analysis, and quality assurance.
