I ingested all my YouTube videos into an LLM wiki and turned them into a connected second brain that my AI OS can actually reason over. In this one I show you how to build the same thing in about five minutes using Claude Code and Obsidian, based on Andrej Karpathy's LLM knowledge base idea. You drop in sources, the AI reads them, splits them into cross-linked wiki pages, and keeps the whole thing organized with routing rules so it can find anything fast. By the end you'll know how to set up the vault, write the schema, ingest a PDF and a URL, and decide when to keep your wiki flat versus structured.

Fable 5 is back, and it's the strongest model I've used. It's also expensive and won't stay free on your Claude plan for long, so this video breaks down the six habits I'm using to get the most out of it without burning tokens. Everything from giving it the right context, to matching effort levels, to knowing when it quietly hands your task off to Opus.

Everyone wants an AI second brain, but almost nobody talks about the fact that there are different levels to building one, and the highest level isn't always the right one for you. In this video I break down all five levels of a Claude Code second brain, from a simple CLAUDE.md router all the way up to an always-on autonomous system, using my real Herk2 project as the example. The goal isn't to climb to level five. It's to find the lowest level that actually solves your pain so you stop re-explaining things and your agent always knows where to look.

When I started the AI Automation Society, I had no idea it would grow into this. Under two years later and we just crossed 400k. The largest AI automation community in the world. Yes, the space is exploding. But this community grew because you guys keep showing up, asking questions, dropping answers, sharing builds, and helping the person one step behind you. Huge thank you to the team that keeps this thing running, and to every single one of you who's posted, commented, or just been here. I feel lucky to get to do this. So excited to share with you guys what we've been quietly cooking up over here at AIS...👀 - Nate

My entire life and business now live in one second brain, and Claude Fable understands it better than I do. In this video I walk through my full Claude Fable AI operating system using the four Cs framework: context, connections, capabilities, and cadence. You'll see exactly how my files and folders are set up, how I keep improving it every day, and the usage tips I rely on to get more out of it.
