BACK ON YOUR BOARD

Outline the idea

Build the first version

Try it on another device

Choose board-wide read and write permissions. Your drive and inbox stay out of it.

Keep something private. Pass something useful. Pick up where you left off.

A home, not another hurdle.

Some things stay private.
Some things need to move.

  1. 01

    Keep it somewhere you can find it.

    Save everyday notes and links on your board. Put sensitive content in the separate vault, encrypted on your device and opened on devices you trust.

  2. 02

    Get it onto the other screen.

    Your saved items follow your sign-in. For a quick handoff, show the QR code for a regular item: someone scans it and opens that one item. No recipient account needed.

  3. 03

    Make room for an agent, not your whole life.

    Connect an MCP-compatible agent, choose board-wide permissions, and ask it to use your saved context or leave a result back. Your inbox and drive are not connected.

A few useful details

Your stuff.
Your call.

What can my agent access?

What you save to PasserJack, according to the key permissions you grant. Read and write permissions cover your board, not individual items. Vault reads require a separate permission and an unlock window you open. You can revoke a key at any time. Connecting PasserJack does not connect your filesystem, Gmail, or cloud drive.

Do I need an agent to use it?

No. It is a useful place to keep and move notes, links and snippets between your phone and computers. Agents are optional. Connect one through MCP or the REST API whenever it helps.

Is everything end-to-end encrypted?

No. Ordinary board items are stored so you can search and share them. The separate vault encrypts content on your device; agent access to it requires an explicit unlock. Titles and filenames are metadata, not encrypted content.

Can I share with another person?

Yes. Create a link to an item, choose when it expires, and revoke it when you are done. Someone who can read a shared item can still copy it.

How does the QR handoff work?

Open the QR code for an item and scan it on another device. For a regular board item, anyone with that handoff link can open the item once, for 5 minutes, without signing in. It does not give access to the rest of your board. A QR code for a vault item sends you to the vault, where sign-in and vault access are still required. The QR codes in these examples open the public PasserJack homepage, not a real saved item.

What should I do first?

Sign in, paste a link you want on another device, then open PasserJack there. That is the whole first step. No agent setup or installation needed.

Pick up where you left off.

Your work moves.
Your stuff should, too.
