Overview

Retell AI is a platform for building phone-based voice agents with an emphasis on natural-sounding, low-latency conversation. It is often described as code-first and inbound-focused: developers wire up call logic through its API and SDKs, and the platform handles the real-time speech pipeline and telephony. In practice its reputation is for voice quality — the agents tend to sound less robotic and handle interruptions more gracefully than some rivals — which makes it a common pick for customer-facing lines where a stilted bot would cost you. Per-minute pricing varies with the voice and model you select, and like other bring-your-own-component platforms the advertised rate excludes the LLM tokens and telephony you pass through. It sits alongside Vapi as a developer tool rather than a drag-and-drop builder, so non-technical teams will find the ramp steeper than a no-code product. The same compliance points apply as for any automated calling system: disclose the AI caller where required and stay within TCPA and equivalent rules for outbound campaigns, because that responsibility rests with you.
