About Retell AI
Retell AI is a platform for building AI agents that answer and place phone calls, such as receptionists, appointment schedulers, dispatchers and customer service lines. Agents are built with templates and a flow editor or through the API, can transfer to a human, navigate phone menus, look things up in a knowledge base and book meetings. It also handles batch outbound campaigns, branded caller ID and post-call analysis. Pricing is pay as you go with no contract: you pay a per-minute voice infrastructure fee plus the language model, voice and telephony you choose, with a cost estimator on the pricing page. New accounts get free credits and 20 concurrent calls. An enterprise plan adds SSO, role-based access, custom BAA and DPA terms and dedicated support. Compared with Vapi it is a little more ready-made for business use cases, while still letting developers pick models such as GPT, Claude or Gemini. The company came out of Y Combinator and runs entirely in the cloud.
Best for: Businesses and agencies building AI receptionists, schedulers or outbound call campaigns.
