About Retell AI
Retell AI is a platform for building AI voice agents that answer and make real phone calls. You can use it for a receptionist, appointment booking, lead qualification, and customer service, with inbound and outbound calls.
How the pricing really works: Retell AI is pay-as-you-go, with no platform fee, no monthly minimum, and no contract. The headline rate is $0.07 to $0.31 per minute, built from voice infrastructure $0.055 per minute, text-to-speech $0.015 to $0.10 per minute, a language model $0.0016 to $0.384 per minute depending on the model, and telephony $0.015 per minute (free if you use your own SIP trunk). Billing is per second, and only connected calls are charged. A phone number costs $2 per month. Add-ons cost extra per minute: Knowledge Base $0.005, PII Removal $0.01, and AI QA $0.10 per minute with the first 100 minutes free, plus SMS $0.01 per message. Speech-to-speech models are priced separately, up to $0.38 per minute.
The honest catch: there is no free plan, only a one-time $10 signup credit, and the per-minute cost swings a lot depending on the model you pick.
