Speak to Fill

Speech

Say "table for four next Friday at seven, outside" and watch the booking form fill itself — speech in, structured data out.

Why On-Device?

Voice hits the on-device recognizer, the transcript hits the on-device LLM with a JSON schema, and the form fills — no audio or personal details ever reach a server.

Interactive Demo

Web Speech (on-device): Loading...
Prompt API: Loading...

Tap and say something like
"Table for four next Friday at seven, outside."

No mic? Type the utterance

Utterances refine the form — try the corrections after the first one.

Reservation at Chez Nimbus

The confirm button unlocks once name, date, and party size are filled.
