Know when to speak.
Know what to say.

Deban sits beside you in Google Meet, Zoom or Teams. It listens locally, recognises who is talking, and taps you on the shoulder the moment a question is really yours — with a suggested answer in the meeting's language.

Audio, transcripts and memory stay on your Mac. Deban never speaks for you.

鈴木3D生成のデモ用データは、いつごろ揃いそうですか?
● Your turn
鈴木 is asking you when the 3D demo data will be ready.
Suggested: 「今週中には揃う見込みです。品質確認が終わったら金曜に共有します。」 — you promised this on Sep 4 (Deban remembered).

Not another AI note-taker.

Note-takers tell you what happened. Deban tells you, in the moment, that it is your turn — and why.

1

Knows who is talking

Local voiceprints recognise your colleagues across meetings. Anonymous voices get stable labels you can name later.

2

Knows what is yours

Your role, your areas, your past promises and TODOs form a memory. A question about "the 3D data" is matched to you, not to the whole room.

3

Nudges, never speaks

A red card for a direct question, a yellow one for "this might concern you", a blue one when you could add something. You decide.

4

Answers in the room's language

Suggested replies in Japanese or English with three stances — positive, neutral, cautious — and the sources they lean on.

5

Built for cross-language meetings

Live subtitles in your language, answers in theirs. Made first for Chinese speakers in Japanese meetings.

6

Local-first by design

Speech recognition and speaker recognition run on your Mac. Only the text sent to the language model leaves it, and never your audio.

After the meeting

Every meeting becomes a searchable record: transcript with speakers, topics, minutes, decisions, TODOs with owners, and the moments Deban nudged you — each with a 👍/👎 that tunes future alerts.
