The Second Brain

Active

An AI-powered knowledge system that connects ideas, generates content, and powers everything Andrew builds.

The Second Brain is the knowledge system behind everything on this site. It connects notes, ideas, research, and conversations into a structured graph that I can query, explore, and generate from.

It started as an Obsidian vault with some clever tagging. Now it's evolving into something closer to a personal AI that understands what I know, what I'm working on, and what I should pay attention to.

Every episode of Building Out Loud, every project update, and eventually every blog post routes through the Second Brain.
