MyMemoA plain folder you own
Your memories are Markdown files in ~/OpenMyMemo. Open them in any editor, or keep them in iCloud, git or an Obsidian vault.
OpenMyMemoOpen source · Early stage
Your AI memory, in a folder on your own computer.
See exactly what AI apps remember about you. Claude, Codex, Cursor and other MCP apps share one memory, so what you tell one, the others know too — and you see every change they make, with one click to undo.
Free and open source under the Apache-2.0 license. Runs on your computer; no MyMemo account or plan needed.
A new project, at an early stage
OpenMyMemo is a new open-source project at an early stage, so some parts may still be rough. We’d love you to get involved and improve it with us — if something breaks or could work better, open an issue on GitHub.

Memory that doesn’t belong to one vendor.
Today, what an AI remembers about you lives inside one company’s account. If the account is closed, the service shuts down or you switch models, that memory stays behind. OpenMyMemo keeps it as plain files on your own computer, where any model can read it and no single company can take it away.
What it does
You see everything, and you can undo it.
One memory for all your AI apps
Claude Desktop, Claude Code, Codex, Cursor, VS Code and other MCP apps read and add to the same memory.
Every change, reviewable
Additions apply right away and are marked as new until you look. Changes to what you wrote yourself, and anything in a private topic, wait for you. Undo is one click.
See what AI sees
The panel shows the exact text each app receives and which app read what. Health and finance are hidden from every AI by default.
Bring your memory along
Import what ChatGPT, Claude or Gemini already remember about you, and export to Claude, ChatGPT, Markdown or JSON.
Local by design
The server listens only on your own computer. No database, no API key, no telemetry, and no account needed.
Get started
Two ways in, one memory.
Both use the same memory folder, the same panel and the same core, so you can switch or use both. The README on GitHub has the current install steps.
For everyone
The Mac app
No terminal, no config files, no Python to install. A short guide connects the AI apps on your Mac with one click each and brings over what ChatGPT, Claude or Gemini already remember about you. Needs a Mac with Apple silicon and macOS 12 or later.
For developers
Command line and plugins
Install with uv, or add the plugin for Claude Desktop, Claude Code or Codex. Everything the app does is also a command, and the folder format is documented for any tool that wants to read or write it.
Works with
- Claude Desktop
- Claude Code
- Codex (CLI and in the ChatGPT desktop app)
- Cursor
- VS Code
- Other MCP apps
Optional · MyMemo Cloud
Use your memory in ChatGPT and claude.ai on the web.
ChatGPT and claude.ai on the web can only reach servers on the public internet, and OpenMyMemo stays on your computer. The optional MyMemo Cloud connector links your computer to your MyMemo account and passes the web apps’ requests to OpenMyMemo while it runs. Your memory stays on your computer, and MyMemo never keeps a readable copy of it.
Which MyMemo plans include it
Live relay
Each request from a web app is answered by OpenMyMemo on your computer while it runs. MyMemo keeps nothing beyond request metadata.
Included withPro and Ultra subscriptions, and every AppSumo or Oncely lifetime tier
Offline queue
While your computer is off, changes the web apps propose wait for it for up to 30 days, encrypted so only your computer can open them. Reading your memory still needs your computer to be on.
Included withUltra subscriptions, and lifetime tier 3 (three AppSumo or Oncely codes)
MyMemo Free doesn’t include the MyMemo Cloud connector. OpenMyMemo itself stays free and works fully without it.
- The connector does nothing until you sign in from OpenMyMemo, and you can unlink your computer at any time.
- Whether ChatGPT lets a connector propose changes can depend on your ChatGPT plan; reading works either way.
- MyMemo Cloud is rolling out gradually, so it may not be available on your account yet.
