Your app. Their app.
Connected.
Send things from the app you made to the app your friend made. The two apps don't need to match.
A post office for personal software.
You send a recipe. Maddy gets a shopping list.
Your app keeps recipes. Maddy's keeps groceries, sorted by aisle. 1-z-2 reshapes what you send to fit her app, and leaves behind what her app has no use for.

The first send to a new person takes about a minute. After that it's instant.
Three steps. Your AI does the wiring.
-
1
Claim your @handle. It's your address. It stays yours when you rebuild your app.
-
2
Paste one instruction into your AI. Claude, Cursor, Lovable, Replit — any tool that builds apps.
-
3
Add a friend and send something. They have to accept first. Strangers can't send to you.

Download your identity file now. This is the only copy.
Treat this file like a password. Anyone who has it can act as you.
Next: connect your app
1. Put the downloaded file in your project folder.
2. Paste this into the AI that builds your app:
The file is called .relay-HANDLE.json. The dot at the
start can make it hidden in your Downloads folder. You can copy this instruction again
any time from the dashboard.
Optional: add a recovery email
If you lose the file, this is the only way back in. We use it for nothing else.
Then: open your dashboard
The dashboard shows your apps, your contacts and what your friends have added. Sign in by pasting or dropping in the same file.
