We built the quiet tool we wanted to use ourselves.

Twenty-six people in Tokyo, Lisbon and Toronto, handing off to each other every day with the product we make.

Why we built it

In 2023 our team of eleven spent the first hour of every day catching up.

2023
Eleven people, one hour a day lost to catching up.
2024
First brief sent to ourselves. Six lines. It worked.
2025
Opened to 40 teams. Added Ask with sources.
2026
212 teams, 24 languages, offices in Tokyo, Lisbon and Toronto.
How we work

Four words we build by.

間
Ma
Leave space.
A brief that fills the screen has failed. We cut until it fits in ninety seconds.
誠
Makoto
Show the source.
Every sentence can be checked. If we can't show where it came from, we don't write it.
簡
Kan
Keep it simple.
One page, one question box, one setting per thing. Features have to earn a place.
静
Shizuka
Be quiet.
No streaks, no badges, no 'you have 12 new insights'. It speaks when it has something to say.

From teams who read less

Quiet, in their words.

Drag to read · 6 teams

I used to start the day with 300 unread. Now I start it with six lines and a coffee.

Aiko Tanabe
Head of Operations · Ōmi Studio

The sources are the point. I can forward a line to my CEO and she can check it herself.

Rafael Moura
Chief of Staff · Porto Freight

Quiet hours gave me my afternoons back. The two things that came through actually needed me.

Hannah Kessler
Engineering Manager · Lindenfeld

Our Osaka and Lisbon teams finally overlap, even though they never meet on a call.

Kenji Arai
VP Product · Hanakaze Foods

We turned it on for 40 people on a Thursday. By Monday nobody asked for the weekly status meeting.

Priya Nair
COO · Tidewell

It says “I couldn't find that” when it can't. That is why I trust the rest of it.

Sofia Lind
Legal Counsel · Halvard Health
Two sources, four minutes
