Retell AI
– Voice AI Agent Platform
About Retell AI
Retell AI is the first enterprise-grade AI voice platform helping corporate call centers automate tier-one calls using AI voice agents that are indistinguishable from humans. The Retell AI platform reduces labor costs, improves first-call resolution, and frees up human agents to focus on complex or sensitive issues. With rapid no-code deployment and high configurability, enterprises launch the Retell automated voice agents in days—not months. Retell serves thousands of businesses and now powers 30+ million minutes of phone conversations every month.
About Voice AI Agent Platform
Retell's platform is based on best-in-class existing commercial LLMs, with a proprietary real-time conversational AI model layer on top that orchestrates speech-to-text (listening) and then text-to-speech (talking) in a highly accurate manner in real time. Retell spent two years building and perfecting its model.
Retell can handle both inbound and outbound calls, to cover both sales and support use cases. In addition to phone calls, Retell can also handle web calls, SMS and more.

- Truly humanlike voice quality out of the box
