The Brains launches @brainsbot for cited founder takes under X posts

The Brains launched @brainsbot, a bot that answers what a well-known founder or investor would think about a post. Tag @brainsbot under any X post and ask what someone like Warren Buffett, Steve Jobs or Paul Graham would make of it. Questions can be as direct as "would Peter Thiel invest in this?" or "would Bryan Johnson agree?"

The bot draws on 69 brains and cites its answers from what the person actually said. It's powered by Grok, free and open source. The account is automated and unofficial, and replying "stop" opts you out.

It comes from The Brains, a directory where each founder, CEO or investor is a searchable MCP server built from their talks, essays and posts. Add one to Claude, Cursor or ChatGPT and every answer cites its source. Roundtables put several people on one topic, such as pricing, sales or fundraising, in a single MCP.

The brains are unofficial and built from public content. You can request a brain, and people featured can claim theirs to verify it, fix errors and add sources. The project is open source on GitHub and made by Vic.
