Everything that happened, stays yours.
Urda remembers every word you have ever said. Not a single bit of it leaves your home.
Every AI meets you for the first time, every time.
You have spent hundreds of hours talking to AI. It does not know your mother's name, why you dread Wednesday meetings, or what that supplier promised you last spring.
Every session, you carry the context in by hand. You are its unpaid courier.
The industry is racing to make intelligence cheaper. Intelligence is already cheap — it halves in price every few months.
What nobody has solved is smaller and harder: nobody owns your memory. Not even you.
Three parts. Remove one and it stops working.
Stone 记石
A recorder the size of a coin. One microphone, one button, a week of battery. No screen.
Base 记座
A small machine that sits in your home. Transcription, indexing, understanding — all of it happens here.
Look 回头看
One page on your phone. A timeline, and a box to ask a question. It answers with what was actually said.
Wear it. Forget it. Ask later. There is no app to open, no session to start, no model to choose.
Not a single bit leaves your home.
This is not a privacy feature bolted onto a cloud product. It is the definition of the product.
There is no account to create, nothing to sync, no subscription to lapse. Your memory lives on a box you own. If the drive dies, it is gone — the way human memory is gone.
Transcription runs on the box. So does the model that organises your day. There is no API key anywhere in the system, because there is no bill to pay and no reason to phone home.
And it is enforced, not promised: the software refuses to start if you point it at a public address.
URDA_LLM_URL=https://api.openai.com/v1 → refused to start
"points at public address — inference must stay local"
URDA_LLM_URL=http://127.0.0.1:8080/v1 → ok

Real output from the boot guard. Every release is tested with the network unplugged.
Most of the work was deciding what not to build.
- No cameraA microphone makes the room uneasy. A camera makes it hostile. And describing images needs a model we refuse to rent from a cloud.
- No screenAdd a display and you are competing with the watch already on that wrist — and losing a week of battery to do it.
- No chat windowYou get a timeline and one question box. That is the whole interface.
- No cloud accountNothing to register, nothing to sign in to, nothing for us to lose in a breach.
- No subscriptionCharge monthly and you must hold the customer's data hostage. We sell you a device instead.
- No plugin storeA product that does five hundred things does nothing.
- No notificationsIt never speaks first. It is a memory, not a roommate.
Meetings and calls. Never miss a word.
We are not claiming to record your life. Not yet, and not honestly. The first version does one thing completely.
Wear it through a sixty-minute meeting.
Afterwards, ask for any sentence — verbatim, with what came before and after.
Ten seconds. Network unplugged.
That single sentence is the entire acceptance test for v1. If it fails, we do not ship.
The honest answers.
What about the people around me?
This is the hardest problem with this product, and it is not a technical one. An always-listening microphone makes the people near you uncomfortable, and no amount of encryption fixes that. Our answer is restraint and a hardware switch: Stone has a physical button that cuts power to the microphone — not a software toggle you have to trust us about. Recording laws differ by country and by state; some require every person in the conversation to consent. Knowing and following those rules is your responsibility, and we will not pretend otherwise.
What happens if my Base dies?
You lose the memory. That is the honest cost of a product with no cloud. You can back Base up to a drive you own, and we will never make that difficult — but we will not quietly copy your life to our servers so that we can charge you to get it back.
How is this different from the other AI pendants?
They process your recordings on their servers and charge you monthly for the privilege. That is not a flaw in their execution — it is their business model, and it is the one thing they cannot change. Urda processes everything on hardware you own and charges you once. Both approaches are real products. Only one of them can promise that your conversations are not sitting on someone else's computer.
Why is a local model good enough?
For transcription, local models are now as accurate as anything you would rent. For summarising a day, a model running on a box in your house is meaningfully weaker than the largest cloud models — we are not going to pretend otherwise. We think that trade is worth it, and we would rather tell you the trade exists than hide it.
Will there be a camera later?
Not until it can be understood on your own hardware. The moment we add a camera that needs a cloud to make sense of what it sees, the promise on this page is void — and the promise is the product.
Be there when it ships.
Leave an email and we will write once when there is something real to show — a working device, a date, a price. Not a newsletter.
