Walk up
to anything.
There will be a lot of robots, devices, and new kinds of AI in the places we go. Right now each one meets you as a stranger. With Field, you walk up and it already knows the part of you that you chose to share. You don't take your phone out of your pocket. When you leave, its access ends, and what happened comes home to your Field.
Vision · not shipping today
Your context comes with you. The device comes to you.
Today you go to each app and each device, and each one keeps a piece of you. Field turns that around. Your life's context stays with you, and anything that wants to help you asks your Field, on your terms.
01 · NEARBY
It says hello first.
A robot or device announces itself over a short-range signal like Bluetooth LE, UWB, or NFC. It says who it is and what it would like to know.
02 · YOUR RULES
Your Field answers.
Your phone stays in your pocket. Field checks the rules you wrote once. The public layer can be an automatic yes. Anything more is a tap on your Watch.
03 · JUST THIS VISIT
One layer, for a while.
The device gets a scoped grant, not a copy of you. It reads only that layer, and every read is logged.
04 · ACCESS ENDED
You walk away. It ends.
When you leave, access ends. Every grant has an end: when you walk away, at checkout, or when you say so.
05 · HOME AGAIN
The visit comes home.
What happened is saved as a moment in your Field, so the next mind already knows.

Four small stories
What walking up would feel like.
A friend's robot already knows how you take your coffee
You're at a friend's place for dinner. Their home robot notices you at the door and asks your Field what it can know. Your friend is a friend in your Field, so the answer is your friend layer: your first name, no peanuts, and coffee black. It doesn't learn where you live or who else you know. When you head home, its access ends.
Shared: friend layer · Asked: nothing · Ends: when you leaveA new AI device that knows you out of the box
You unbox a new assistant from a company you've never used. Instead of a long setup quiz, it finds your Field nearby and asks for more than the public layer. Your Watch taps your wrist and shows exactly what it wants. One tap and it starts with your name, your units, your morning routine, and what you told your last assistant about this week. You can see everything it read, and you can take it back.
Shared: what you approved · Asked: one Watch tap · Ends: when you say soThe hotel robot knows your stay, not your life
A concierge robot meets you in the lobby. It gets what this stay needs: your name for the booking, a quiet room, a cooler room temperature, and permission to unlock room 412. It doesn't get your history or your family. At checkout the grant is over, and a short record of the stay comes home to your Field.
Shared: stay preferences + room access · Ends: at checkoutA stranger's robot sees only your name tag
A delivery robot on the sidewalk, or a stranger's robot in a park, asks too. It gets your public layer and nothing else, the kind of thing you'd put on a name tag. Maybe a first name and "prefers English." Or maybe nothing at all, if you're in blank mode.
Shared: public layer only · Asked: nothing · Ends: right awayThese are examples. The same handshake would work with everything around you: a shop display that knows your size and style for this visit only, a vending machine, a robotaxi that sets your seat, music, and destination, the TV in a hotel room, a 3D printer that gets your measurements, and your family's devices sharing the family layer. Every visit still comes home to your Field.
Layers
You decide what each kind of relationship can see.
Every device that walks up to you is treated like a person you have a relationship with. You set the layers once, in plain words, and change them any time. Nobody sees how you've labeled them.
| Layer | What it might share | Who gets it | How it's answered |
|---|---|---|---|
| Public | What you'd put on a name tag. A first name, a language, an accessibility need you want known. | Strangers, and robots you've never met | Automatic, if you allow it |
| Friend | Preferences that make a visit easier: food, drinks, how you like to be addressed. | People and devices you've marked as friends | Automatic, by your rule |
| Family | Shared moments, routines, and plans you've chosen to share with family. | Family, and the devices in their homes | Your rule, or a Watch tap |
| Private | Everything else. Health, money, location, other people's information. | No one, unless you open one piece for one visit | Always asks you, every time |
| Blank | Nothing. You start fresh. | Anyone, when you'd like to be new | Field stays quiet |
The loop
Out to the device, and back home.
Every visit runs both ways. Your Field goes out with only what this visit needs. When the visit ends, what happened comes back as a moment in your Field: who you met, what it did, what was said, and what it learned, if you allow that part. The next robot or AI you meet already knows.
- →You keep the record. The moment lives in your Field, not the device maker's account.
- →Learning is opt-in. If you don't allow it, the device's notes about you don't come home and don't stay with the device.
- →Other people stay theirs. Someone else's details travel only under their relationship to the device, not yours.
The promise
Yours. Temporary. On the record.
Owned by you, kept on your devices
Field is local-first. Your memory is a signed log you hold. Devices read a layer of it with your permission. They never own it.
Access ends when the visit ends
Every grant has an end: when you walk away, at checkout, or when you say so. You can also end any of them early.
You can see every read
Each device's visit leaves an audit trail you can open: what it asked for, what it read, and when its access ended.
You can always start fresh
Sometimes you want to be new. Turn on blank mode and nothing answers. Meeting someone without your history is a right, not a bug.
What's real today
This is where we're headed, not what we ship.
Field today is a private beta on iPhone and Mac that carries what you tell one AI to the next. There are no robot integrations and no device partners. The hands-free handshake on this page is design work.
- →Built on open pieces. Short-range radio (Bluetooth LE, UWB, NFC) to notice a device nearby. MCP so any AI can read from your Field. A2A for agents talking to agents. Poppy, the draft Personal Agent Protocol, for how agents meet businesses (not affiliated with or endorsed by Poppy's authors). The draft Field protocol for grants, layers, and moments.
- →None of them does this yet. Each one is a building block. Putting them together into a walk-up handshake is the work ahead, and some of it may need changes to those drafts.
- →An app plus an open protocol. The app is the easiest way in. The protocol is open so other hosts and other devices can take part. $99 once, with a 30-day trial. No subscription.
Want in?
The beta is small and invite-only. Implementers interested in the protocol or in running a second host: we'd especially like to hear from you.
