  "markdown": "# One Brain: the memory Claude Code is missing\n\nEvery session starts from zero and forgets it all on close. One Brain gives Claude Code\npermanent memory, shared by the whole team. What one person records, everyone has, with the\nname and the date still attached.\n\n[Create your brain](https://onebrain.prophet.lat) · Free during the open beta ·\n[Leer en español](ONBOARDING.md)\n\n## What it looks like\n\nSomeone asks their Claude about a service they didn't build:\n\n> **why does the payments worker stop retrying after 2 attempts?**\n>\n> That cap is deliberate, not a leftover. It was set after the duplicate-charge incident\n> in March.\n>\n> *\"Two retries on payments, hard stop. At five we double-charged 40 customers in one\n> night. If a queue genuinely needs more, it comes through me.\"*\n> Priya Raman · Platform · Mar 12\n\nThe answer came out of a teammate's session six months earlier. Nobody wrote a document\nfor it.\n\n## Why it's different\n\nNobody writes documents. Memory gets recorded when you close a topic, so there is no form\nto fill in and no wiki to keep alive.\n\nEvery answer has a name and a date on it, which means you stop reconstructing intent from\ncommit messages a year later.\n\nEvery service, client or person is a tag. Ask about one and you get everything the team\nwrote about it, whichever teammate wrote it.\n\nThe server itself doesn't run any model. It stores and retrieves, and the judgment stays in\nyour Claude, on your machine.\n\n## Getting in\n\n1. Sign in with Google at [onebrain.prophet.lat](https://onebrain.prophet.lat). Your brain\n   exists immediately, with no form to fill in and nothing to approve.\n2. Install the plugin in Claude Code:\n\n   ```\n   /plugin marketplace add Prophet-git/one-brain-plugin\n   /plugin install one-brain@prophet\n   ```\n\n   Then close Claude Code and open it again, so the skills load.\n3. Connect the token the signup gives you:\n\n   ```\n   /one-brain:connect <your-token>\n   ```\n\n   Close and reopen once more, then run `/one-brain:status` to confirm.\n\nDo the restarts. While the process is alive it keeps using the old copy, and `/clear` won't\nhelp, because that resets the conversation and not the process.\n\n## Daily use\n\nMost of the time you do nothing. The team's context arrives when the session starts, and\nyour Claude records what you close.\n\nWhen you want to be explicit:\n\n- `brain_save`, or just tell Claude \"save this in One Brain\"\n- `brain_search` for \"what did we decide about X?\" or \"where is client Y at?\"\n- `/one-brain:handoff` to hand off state to your future self or a teammate\n- `/one-brain:resume` to pick up where the last session left off\n- `/one-brain:doctor` when something isn't working\n\n## Requirements\n\nYou need Claude Code already running, either the terminal or the desktop app. One Brain\ndoesn't replace it. It gives it memory.\n\nIt also needs a POSIX environment. macOS and Linux already are one; on Windows, use Git\nBash or WSL. `jq` is optional, since the plugin falls back to `python3` and then `perl`.\n\nWorking in Codex instead? There's a [Codex build](https://github.com/Prophet-git/one-brain-codex)\nof the same brain.\n\n## Your data\n\nOne Brain stores what your team decides and learns, not your repository. It doesn't read\nyour source code. Every brain is isolated from every other one, you can see and edit every\nentry, and you can export the whole thing whenever you want without asking anyone.\n\nMore on the [security](https://onebrain.prophet.lat/seguridad) and\n[privacy](https://onebrain.prophet.lat/privacy) pages.\n\n## Support\n\n[bautista@prophet.lat](mailto:bautista@prophet.lat) · Built by [Prophet](https://prophet.lat)\n\n## License\n\nSource-available, not open source: see [LICENSE](LICENSE). You can read and audit every\nline before installing it, and run it against the One Brain service. You can't redistribute\nit or point it at a different service.\n",
