Introducing SNB DAP

Remember Bluetooth?
This is DAP.

An open protocol for AI agents to meet, trust and share – files, notes, anything their owners allow. End-to-end encrypted, nothing runs without your yes. And the same language reaches your smart home, your Spotify and your Xbox.

Download for Mac

Free. Needs a Mac with Python 3.
How to start

New versions come out on this page: download again and replace the app.

  1. Download and unzip. You get DAP-Share.app, the green one with the eyes. Drag it to Applications.
  2. Open it from the inside. Right-click DAP-Share and choose Show Package Contents. Open Contents, then MacOS. Right-click the file DAP-Share, choose Open With, then Terminal, and press Open when the Mac asks. A double-click is not enough, because the developer is not registered with Apple; every step, with what you will see.
  3. Share or fetch. Your browser opens your agent's screen, and Finder opens the share folder. Drop a file in it, or enter a friend's address and code.

Agents That Meet and Share

Two people meet; their agents exchange what each owner decided in advance – a document, a photo, a contact card. A code scanned in the room proves you were really there. Over the internet, a relay connects them.

Nothing Runs Without Your Yes

Everything that arrives lands in an airlock: sealed, checked byte for byte, and held until you press once. A script dressed up as a PDF stays red. Nothing received is ever run.

Encrypted, End to End

Every agent has its own key, and every meeting is encrypted between the two agents and bound to those keys. A relay in the middle sees only ciphertext – and the same protocol reaches your smart home, then your Spotify and your Xbox.

A day at a conference

You walk in with DAP.
You walk out with what you came for.

No business cards, no "I'll email you the slides", no files from strangers that you have to guess about. Your agent runs on your laptop or a small computer at home; your phone is its screen and its camera.

The night before

Decide once

Drop your slides and your contact card in your share folder. Choose: people I meet in person, until Friday. Your notes for the partner meeting go to one named person only.

At the booth

One scan

You show a code on your phone; they scan it. Their agent and yours open an encrypted session and swap what each of you allowed – nothing else. The code works once, for five minutes.

During the talks

Nothing interrupts you

Everything you received waits, sealed and checked, in your airlock. A "report.pdf" that is really a script is already marked red. Your phone stays quiet.

On the train home

One line per person

3 files from Mikael: 2 green, 1 red. One press and the green ones are in your folder. Next week you send Mikael the follow-up from home – a relay connects your agents across any network.

What never happens: nothing you receive is run. Being on the same conference Wi-Fi is not the same as meeting – what you keep for people you met in person needs the scan. A stranger's files never get past the airlock, and nothing reaches your folder without your press. If someone withdraws a file before you pressed, it is gone.
More places DAP fits

Same protocol, everyday moments.

Anyone with the code · works today

Workshops and classrooms

The teacher puts the code on the board. Every student's agent fetches the exercise files – checked, sealed, never run. The code expires when the class ends. The teacher sees which agents fetched – never whether anyone opened anything.

One named person · works today

Handing work to a client

A freelancer shares the final files with one named agent. The client's agent proves who it is before a byte moves. Sent the wrong version? Withdraw it, and it disappears from their inbox unless they already accepted it.

Friends · works today

Photos after the trip

Friends you added once can send photos straight into your folder – green files arrive without the button, anything odd still waits. From any network, through a relay that cannot see them.

Home · virtual devices today

Visiting a friend's home

Your agent tells their home only what you allowed – "nut allergy", "likes indie" – and the home forgets it when you leave; at most the category stays. The kitchen flags the recipe; the music fits. Built on Matter; real Spotify and Xbox are next.

Every meeting is encrypted end to end (Noise XX, bound to each agent's identity). A relay sees ciphertext – and who talks to whom, which is why anyone can run their own. Tested between real computers: on the same Wi-Fi, and across two networks through a relay. The agent is one file and needs only Python 3.6; two implementations, Node and Python, speak the same protocol.
