From the README
The infrastructure layer for your thinking. One database, one AI gateway, one chat channel. Any AI you use can plug in. No middleware, no SaaS chains, no Zapier.
This isn't a notes app. It's a database with vector search and an open protocol — built so that every AI tool you use shares the same persistent memory of you. Claude, ChatGPT, Cursor, Claude Code, whatever ships next month. One brain. All of them.
Open Brain was created by Nate B. Jones. Follow the Substack for updates, discussion, and the companion prompt pack. Join the Discord for real-time help and community.
If you hit a wall: We built a FAQ that covers the most common questions and gotchas. And if you need real-time help, we created dedicated AI assistants that know this system inside and out: a Claude Skill, a ChatGPT Custom GPT, and a Gemini GEM. Use whichever one matches the AI tool you already use.
