Both halves of a phone call. Taken through the handset, not from it.
Say it once.
A recorder you wear. Five recording hours a month, included.
Nobody minuted it. The call in the car park. The decision in a corridor. The promise with a date on it. It happened, and then it was gone.
Brieflee One is a 16 gram disc you wear. It records the call, the room and the thought on the way home, and it sends every one of them back to you written down: a transcript with speakers, a summary, the decisions and what was promised.
Drag, or use the arrow keys.

Both halves of a phone call. Taken through the handset, not from it.

The meeting nobody booked. One button, no invitation, nothing to join.

Sixteen grams. Clip, lanyard, band, or the back of your phone.

The thought on the way to the car. One press, and it is a voice note.

12 to 16 hours on a charge. 8 GB on board, so the phone can stay in a pocket.
Phone calls
A phone call is the one conversation no recorder has been able to reach, because the other person's voice is inside somebody else's handset. Brieflee One does not ask the phone for it. A contact and vibration sensor takes the far side through the body of the handset, and two microphones take you. Your phone's own call recording is never used, and the device is never a party to the call.

for your own side of the call
Magnetically, on the back, where MagSafe would sit. A magnetic ring is supplied for phones without it.
No dial-in, no three-way, no carrier feature, no app in the call path. The device hears the handset the way your ear does.
Recording a conversation is regulated in many places. The ring of light is there to make the disclosure easy; it does not make it for you.

Rooms and notes
Most of what a working day settles is settled somewhere a calendar never reached: a corridor, a car park, the ten minutes after everyone else has left. Press the button and it records. There is no invitation to send, no link to join and nothing for anyone else to install. The thought you have walking back to the car is a voice note.

it records with no phone nearby
A single button on the edge, where a thumb finds it without looking. Press to start. Press to stop.
Storage on board means a meeting is recorded whether or not anything is paired, connected or charged in your pocket. It syncs when it next can.
IPX4: resistance to splashing water from any direction. It is not a rating for immersion.
Design
A matte charcoal disc, 6.8 mm front to back and about 16 grams. It sits on a lapel without pulling the cloth out of shape.
Drag to turn
The face. A ring of green light. It is lit whenever the device is recording, and it cannot be switched off.

On board
8 GB of storage, so it records with nothing else in the room. Bluetooth 5.3 and Wi-Fi for the sync afterwards.

The green ring
A ring of light on the face, lit whenever the device is recording. There is no setting, on the device or in your account, that turns it off.

Wearing it
A magnetic clip on a jacket, a neck lanyard, a wristband, or the back of your phone. Every one of them is in the box, and it charges on a magnetic dock.
Afterwards
Recordings sync to the Brieflee account you already have. What arrives is not an audio file to listen to again: a transcript with speakers and timestamps, a summary, the decisions, and the things people promised, carrying the dates they said out loud.
Pricing was agreed at the volume tier rather than list. Delivery moves to the fourteenth because their warehouse is closed the week before. Legal review is the only thing still outstanding, and it sits on our side.

The week before is no good for us, the warehouse is shut. Let us say the fourteenth, then.
You · 21:44
The fourteenth works. I will send a revised schedule on Friday.

On the phone
On the back of the handset, held magnetically, which is also where the contact sensor needs to be to hear the far side of a call. A magnetic ring is supplied for phones without MagSafe.

Hours
Buy the device once. Five recording hours arrive every month. Beyond those, one credit an hour from the balance your Brieflee account already holds. There is no second subscription, and none is needed to use the device.

Brieflee One is in prototype development. Every figure above is a design target rather than a measured or certified result, every image on this page is a render or a studio visualisation of the prototype, and no certification, review or customer reference is claimed anywhere, because none exists yet.
