Prove age. Never ask for ID.
Age estimation from voice in under four seconds. No ID upload, no documents, nothing sent to a server. Meet every major age-gating law with a single integration.
How it works
One signal. On-device. Two seconds.
Voice-only. On-device. No selfie, no ID, no server round-trip, no PII event to disclose.
- Capture
Two seconds of speech
User reads a short prompt aloud. Features (formants, pitch, vocal-tract resonance) are extracted locally. Raw audio is discarded immediately.
- Estimate
On-device age inference
A model trained on hundreds of thousands of real-world voice samples estimates age from the extracted features — entirely client-side, no server round-trip.
- Prove
Signed verdict, nothing stored
Returns a signed pass/fail proof for the session. No biometric vector retained, no recording uploaded. Full audit trail for compliance.
