Retell AI: pricing, features and what we test
What it is and who it is for
A factual profile, not a review or a ranking.
Retell AI is a voice AI platform, not a finished receptionist. A business or an agency uses it to build its own voice agent, with call transfer, a knowledge base, post-call analysis and an API. It connects to Twilio for phone numbers.
Retell publishes pay as you go pricing from $0.07 to $0.31 a minute depending on the options chosen, plus custom Enterprise pricing.
Because every receptionist built on Retell is configured differently, the benchmark will score a named reference receptionist built on the platform, disclosed on this page, rather than the platform in the abstract.

Benchmark score
Scores appear only after real people place test calls.
No test calls have been made to Retell AI yet, so there is no score, rating or ranking on this page. When real people have called a reference setup, the results will appear here against each of the nine rubric categories, with the setup disclosed. Because Retell AI is a builder platform, the benchmark will score a named reference receptionist built on it, and name that receptionist here.
What our test calls will check
Every product is scored against the full nine category rubric. Given what Retell AI publishes, these are the calls we will look at most closely.
- 01Latency and talk-over, which depend heavily on the models chosen in the build

- 03Call transfer to a human, including when the transfer target does not answer
- 04Post-call analysis compared with what our testers heard
Rubric categories: R1 Greeting and identification, R2 Understanding intent, R3 Booking accuracy, R4 Handoff to a human, R5 After hours and urgent calls, R6 Edge cases, R7 Invented information, R8 Latency and talk-over, R9 Message accuracy.
