A Retell AI alternative you create by describing it.
Retell AI gives you a dashboard to configure phone agents. A Callable starts with a plain-language brief.
Where Retell AI fits.
Retell AI is a voice AI platform built around a dashboard for configuring phone agents, with API access for custom integrations and an on-premises option for enterprise teams.
How the two compare.
Six differences from what both sides publish.
| Aspect | Callable | Retell AI |
|---|---|---|
| How you build it | Describe the line in plain language. The builder asks what it can't infer and drafts it. | Built through Retell AI's dashboard, with API access for custom integration. |
| Where it runs | Your own phone number, on its own dedicated server. | Retell AI's cloud dashboard, with an on-premises option for enterprise. |
| Cost visibility | Every call has an itemized receipt: carrier, transcription, model, and voice, each with its source and rate. | Retell publishes $0.07–$0.31 a minute for voice agents — its own voice infrastructure, plus speech, model, and telephony components. |
| Testing before live | Drafts run through scripted test conversations before publishing. | A live demo and free trial, per Retell AI's own site. |
| Who it's for | Teams who want to describe a phone line, not maintain one. | Teams who want a configurable dashboard for call flows. |
| Code required | None — describe it, review the draft, publish. | Not to start — the dashboard is the default; the API is optional. |

Straight answers about switching from Retell AI.
Six questions people ask before moving a line off Retell AI.
No. Describe what it should answer and refuse, and what callers need to leave behind. The builder asks what it can’t infer, then drafts and tests the line. There’s no dashboard flow to rebuild and no API integration to write first.
Not Retell AI’s own dashboard defaults specifically, but Callable’s own provider list, per line: OpenAI, Gemini, or Grok to decide what to say; Soniox or Deepgram to hear the caller; Cartesia, ElevenLabs, or Inworld to speak the reply; Twilio or Telnyx to carry the call. The builder sets a default stack; any of the four can be swapped.
On its own dedicated server, shared with no other Callable — not a slot inside Retell AI’s cloud dashboard infrastructure.
Yes, in place of Retell AI’s own live demo and free trial. Before publishing, a draft runs six graded caller scenarios as text conversations through the builder’s playground path, and every transcript is graded. Nothing goes live until you press publish, and every publish is recorded.
About $0.062 a minute on the default stack, at the providers’ published rates, itemized by layer on every call: carrier, transcription, model, voice — see /cost. Retell AI publishes $0.07–$0.31 a minute for its own voice agents, as a range rather than a per-call receipt.
Buy a number in the dashboard and point your line at it — no rebuilding the dashboard flow a Retell AI number depends on. Once bought, it’s yours in the dashboard, whether you’re switching from Retell AI or starting fresh.
About $0.062 a minute on the default stack, at the providers’ published rates, itemized by layer on every call: carrier, transcription, model, voice. See the price book →
