Building a self-maintaining second brain with three Grok Bot agents
A walkthrough of setting up three Grok Bot agents in one group chat—reader, librarian, checker—to collect sources, maintain a wiki, and flag contradictions nightly.
holy sh*t. Your AI can now keep a second brain that builds itself. Karpathy’s pattern, running on Grok Bot stop explaining yourself from scratch every chat. three bots share one group chat, each with its own memory: the reader takes in whatever you drop (links, PDFs, voice notes) and never edits it the librarian updates every wiki page that source touches, usually 10 to 15 pages the checker works at night and hunts for contradictions, stale claims and pages with no links pointing to them → you ask something: the answer gets saved as a page, so the brain grows from use, not only from reading → new info conflicts with an old page: the checker tags you instead of overwriting it → 30 days without a fresh source: the page is marked unconfirmed a second brain can sound sure and still remember the wrong thing Reader collects. Librarian writes. Checker doubts. every page has to show: the claim the source it came from the date it was last confirmed paste this into Grok Bot: “Build me a second brain with three bots in one group chat. Keep my sources untouched in raw/, maintain wiki/ yourself, file good answers back as pages and run a nightly check for contradictions. Show me the structure first. Do not create anything until I confirm” start with one topic you actually work on, not your whole life full setup below
