About OB1

Open Brain 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.
