Autophonix, LLC
Voice AI platform for building inbound and outbound phone agents, priced from 2 cents per minute with record-setting audio accuracy.
Key features
- Multi-Transcript Audio Fusion: Combines several transcription models with direct audio-to-LLM input so noisy calls, accents and spelled-out identifiers resolve correctly instead of drifting off-script.

- Live Supervision: Watch calls in progress and whisper guidance to the AI mid-conversation without the caller hearing.
- No-Code Platform plus REST API: Operators launch agents from a front end with A/B experiments and AI-graded test calls, while developers POST to /v1/calls against the same runtime.
