In this short video, the speaker introduces a personal “brain” built by combining the note‑taking app Obsidian with an AI assistant. Every meeting, idea, decision, and spoken commitment is captured, processed by the AI, and stored in a linked‑graph structure inside Obsidian. The system enables natural‑language queries such as “What commitments are due today?” allowing the user to stay present and creative. The speaker emphasizes that the more the user talks to the system, the better it becomes, and invites viewers to comment “brain” to receive a detailed setup guide.

What is that? This is my brain. A little complicated, but let me explain. You download this app, it's called Obsidian. Think of it like a giant web. Every meeting I have, every idea that I capture, every decision I've ever made, when I've talked about it, it gets processed by the AI and gets put into this brain. It's got everything. For example, if somebody made a commitment to me to get something done by Thursday, I can just say, what are all the commitments that people are supposed to get to me today? And it'll go bloop. So now I can just be present, be creative, and the more I talk, the better it gets. And if you want my full guide on how you can set up your brain yourself, just comment brain below and I'll send you the link.
