Notice · iPhone · Apple Watch · Wearable

A companion that listens. Nothing leaves your phone.

Hold the button, say what is on your mind, let go. Notice hears you with on-device speech recognition, thinks with an open language model running on your phone's own chip, and answers out loud. No account, no server, no API key.

Needs an iPhone with 8 GB of memory (iPhone 15 Pro or newer, iPhone 16 or newer) and 2 to 5 GB free for the model.

Notice on iPhone, listening while the button is held — Hold the button.

Notice

Three ways to talk. One brain.

Every word is heard, understood and answered on your iPhone. The watch and the wearable just carry your voice to it.

Notice on iPhone, speaking its answer aloud

On your phone.

Hold the orange button and speak, or type. Notice answers out loud, in any of Apple's voices or your own Personal Voice. The transcript waits behind Face ID in the Memory tab.

Notice on Apple Watch, idle with an orange dot ready to press

On your wrist.

Hold the dot, say it, let go. Your watch carries your voice to the phone, the phone thinks, and the watch speaks the answer back. Nothing else in the chain.

The Notice wearable: a small round device with a glowing face and one orange button

In your pocket.

A small round face, one orange button, a loop for your wrist. It talks to your phone over Bluetooth and to nothing else. Open hardware, designed in the open.

The Notice device

A face that shows how it feels, never what you said.

The six faces of the Notice device: resting, listening, thinking, speaking, pairing and battery — Six states and nothing more: resting, listening, thinking, speaking, pairing, battery. The screen never shows a word of the conversation, so nothing is on display if you set it down.

The Notice wearable between a credit card and an iPhone, for scale — Smaller than a credit card. Hangs from a wrist loop or a lanyard, lives in a pocket, and runs all day on its own battery.

One button. Press and hold to talk; let go and it answers through its own speaker.
Pairs once. A code on its face, the first time only; after that it finds your phone by itself.
Nothing inside to leak. No model, no key, no conversation lives on the device. It is ears, mouth and face; the phone is the brain.

Open hardware

Get one, or make one.

The wearable will be sold two ways: assembled and ready to pair, or as the plans to print and build your own. Both are being finished now.

The assembled Notice wearable, ready to pair

The device, assembled

Printed shell, board, battery and cord, assembled and tested, with a wrist loop. Pair it to the app and talk.

Notice wearable shells printed on a 3D printer bed

The build plans

The printable parts, the parts list and the illustrated step-by-step guide, for anyone with a 3D printer and an afternoon. You buy the board and the small parts yourself.

Tell me when it’s ready

The Notice wearable's shell tilted open above its board — Designed to be built at a kitchen table: everything plugs into the board, the shell swings over it, four screws.

What it does

A mind you choose. Download an open model once and keep it. Qwen3 4B is the one we tested; Llama 3.2 3B and Gemma 3 4B are on the shelf, and you can add any MLX text model from Hugging Face by name. The download is the only time Notice uses the internet.
A memory that is yours. The conversation lives in one encrypted file on your phone, behind Face ID. Erase it with one tap. Never backed up to a cloud, never synced anywhere.
A voice you like. Any of Apple's voices, or your own Personal Voice.
An optional wearable. Notice also pairs over Bluetooth with the open-hardware Notice wearable: a small round face and one orange button, so you can talk without taking the phone out. Everything still runs on the phone.

Notice

Private by design

Notice has no account, no analytics and no ads. Your speech becomes text on the phone, the text goes to a model running on the phone, and the answer is spoken by the phone. The only time it touches the internet is to download the model you chose. The wearable and the watch carry audio to the phone and nothing else. We could not read your conversations if we wanted to; there is nothing on our side to receive them.
