Free · open source · private

Your second brain. On your computer. Owned by you.

A free, private place for everything you want to remember — organized for you by an AI you already have. Drop your files in; it sorts them and learns who you are. Nothing leaves your machine unless you say so.

Download for macOS Download for Linux Windows — coming soon

Free and open source. You'll need a Claude or OpenAI account — that's the only requirement.

What you get

A folder that organizes itself.

Sorts your stuff

Drop bank statements, notes, receipts, PDFs — anything — into one inbox, say "sort my inbox," and your brain files it all into sensible areas it names for you. It never deletes or changes your files; it just puts them where they go.

Knows you

It answers questions from your own documents — "when's my car insurance due?", "what did I spend on the trip?" — from files on your computer, not the web.

Stays private

A little local dashboard shows what your brain knows and how it's organized. It only opens on your own machine. Nothing here phones home.

How it works

Three steps to your first "wow."

01

Install

Double-click the download for your OS. A folder appears in your home and a small icon appears in your menu bar or taskbar. No setup, no terminal.

02

Meet your brain

Open the folder in Claude Code or OpenAI Codex. It introduces itself, asks you five quick questions, and it's ready.

03

Drop your stuff in

Put a pile of files in the inbox and say "sort my inbox." Watch it organize everything — and tell you one true thing it noticed about you.

Your guarantees

Three rules your brain never breaks.

Private by default

Everything stays on this computer.

Nothing leaves without a click

Your brain never sends anything out unless you ask. Only items you choose to mark Shareable can ever leave.

Never a cage

It works for you. Read, move, or delete anything by hand. To uninstall, delete the folder. No account to close.

Optional

Connect to the lattice.

When you choose to, your brain can join the Zuzora lattice — an opt-in network that quietly matches you to opportunities, without revealing who you are until you both choose to. Your identity is created on your own device, and your private key goes into your operating system's keychain.

Only what you mark Shareable is ever shared — everything else stays put. You can disconnect any time. Off by default.

Installing safely

New apps get a first-time prompt. Here's how to open it.

Because this is a free download from a small team, your OS may show a caution the first time — standard for new apps, not a sign anything is wrong. It's open source — the full code opens to the public soon, so you'll be able to read every line yourself.

macOS

If you see "can't be opened," right-click the app → Open → Open. You only do this once.

Windows

If you see "Windows protected your PC," click More info → Run anyway.
