The Brains turns founders, CEOs and investors into MCP servers. Each brain is built from one person's talks, essays and posts: Paul Graham, Naval Ravikant, Pieter Levels, Alex Hormozi, Lenny Rachitsky, Guillermo Rauch, Warren Buffett and 40 more. Ask "How would Levels price this?" and Claude answers from what he actually said, with a link and a date for every passage.
Watch out
- The brains are unofficial, built from public content, except for founders who claimed their own. Check the cited source before you quote it.
- Each brain is a curated set of 15–45 long-form sources and a few hundred posts, not everything the person ever said.
- The first connection asks for your email and a 6-digit code. Sign-in is free.
