A developer-first voice agent platform — the same job as Retell, aimed at people comfortable in code.
You're a developer who wants API-level control over the call pipeline more than a friendly builder UI.
Developer-oriented surface where Retell is UI-oriented
Near feature parity with Retell on the fundamentals
Builds and runs voice agents with LLM, voice and function wiring
Doesn't match Retell's tuning UI, which is why the trainer prefers Retell
The same voice-agent seat as Retell; pick on interface preference.
Voice
No voice use case.
None.
