brain

Every AI you use.
One memory.

brain gives Claude, ChatGPT and your other agents the same memory about you: who you are, what you're working on, the pages you saved. It lives on your Mac, not in anyone's cloud.

sample memory
→ every card points to 1

Every AI starts from zero.

ChatGPT remembers a few things. Claude, a few others. Your code editor, nothing. You end up explaining yourself again in every app. brain is one memory they all read and add to.

One card they all read. What one learns, the others know.

What's in the drawer

brain keeps five kinds of cards. Your agents read them before they answer and write new ones as they learn.

Tell it who you are, once

Your name, what you do, how you like to work. Every agent you connect reads it before answering, so you stop introducing yourself.

Yours, on your Mac

Where your memory livesLocal
Everything brain knows about you is a folder on your computer: ~/.brain. Nothing is uploaded, and no account exists to sign in to.
Rules of the drawer7

    Runs on your machineSearch is powered by a small model that runs locally. brain only goes online when you ask it to save a web page.
  2. 7.2
    Every change can be undoneEach edit is kept as a version, so an agent can never destroy what you wrote.
  3. 7.3
    Agents stay inside the drawerThey can read and write your brain folder, and nothing else on your computer.
  4. 7.4
    Source availableMIT with the Commons Clause. Read every line on GitHub, change it, make it yours. Just don't sell it.
