Retell AI
Build, deploy, and monitor AI voice agents for inbound and outbound phone work, with usage-based pricing.
About Retell AI
Retell AI handles the full operating cycle for AI voice agents: build, test, deploy, and monitor them for real phone workloads. It covers inbound and outbound calls, with ready workflows for appointment booking, lead qualification, reminders, collection notices, and large campaigns. Batch Call launches personalized outreach from either the dashboard or API and tracks each call through its outcome. For scheduling, an agent can check current availability, agree on a time in the conversation, and write the appointment to the right calendar. Branded Caller ID displays a company name on supported U.S. networks such as T-Mobile, AT&T, and Verizon. The standard plan charges by usage. Voice AI is listed at $0.07 to $0.31 per minute with 20 concurrent calls included, though the bill changes with the LLM, voice infrastructure, text-to-speech, telephony, and add-ons. Enterprise pricing is custom; its options include a dedicated stable server, custom SSO and agreements, role-based access control, more concurrency, and dedicated support.

- Enterprise options cover dedicated infrastructure, role-based access control, custom SSO, and dedicated support.
Cons
- The per-minute total varies with the LLM, text-to-speech, telephony, infrastructure, and add-ons, so the headline range is not a fixed bill.
