A chit card floating above a city under fog, reflecting the skyline.

chit one

AI. In your pocket.

Press it and talk. chit listens, understands, and hands your day back to you — written down, summed up, and pointed at what to do next.

From $129, plus $9 a month.

Capture

Press it. Say anything.

The idea at the red light. What the client actually agreed to. The thing your doctor said that you were too rattled to write down. chit is the difference between a thought you had and a thought you kept — and it takes one press and no attention at all.

Macro of the display, lit — a live audio meter, the battery level and the connection status.
The meter moves with your voice. When it stops, so did the recording.

Your day

Your day, waiting for you.

By the time you sit down, it's written. Every conversation you captured, gathered into one brief: what happened, what was decided, and the handful of things that genuinely need you next. Not a list of everything — a list of what matters.

YOU

Okay — walk me through where we landed on the Henderson build.

MAYA

Framing's done. Inspection is Thursday morning, and if it passes we pour the following week.

YOU

I'll need the revised quote before then. Can you send it by Friday?

MAYA

Friday works. We should also loop in the electrician before the pour.

YOU

Good call. Let's do a walkthrough Tuesday at two.

Design

Thin enough to forget.

chit one is the footprint of the cards already in your wallet, at 3.9 millimetres. No lanyard, no clip to snag on a seatbelt, nothing to unlock. It disappears until you need it, which was the only design goal that mattered.

Connections

It knows what's on your calendar.

Connect your calendar and your mail and chit stops guessing. It knows the meeting you just walked out of, so the summary arrives with a name on it. It knows who was in the room, so the follow-up is addressed. A next step stops being a line of text and becomes an event on Thursday or a reply already drafted.

It only listens when you press it.

There is no wake word and no always-on microphone. Nothing is captured unless your thumb is on the button, and you can delete any capture — audio, transcript and summary — in one tap. Your voice is never sold and never used to sell you anything.

Stop losing the good part.

In stock, ships free, and if it doesn't earn its keep in thirty days, send it back.
