About Retell AI
Retell AI is a web platform for building, deploying and managing AI voice agents that handle inbound and outbound phone calls.

The platform adds call-center tooling: outbound campaigns with pacing and retries, IVR navigation, CRM context in and call outcomes written back, live monitoring with instant human takeover, QA of up to 100% of AI calls, and custom analytics from post-call metrics with A/B comparison of agent versions.
