Stop Using Obsidian. This Simple Second Brain Setup Actually Works

Most second brain setups are beautiful and completely useless. You spend a weekend wiring up Obsidian, end up with a gorgeous knowledge graph. Then realize every single node in it is something you've had to type by hand or clutters your desktop. In this video, I break down why the Obsidian second brain fails and the alternative setup I actually use: A second brain my AI fills on its own, while I'm asleep. An operating system and knowledge layer my running agents share. No Obsidian at all. No plugins. No folder structures. One link, two minutes, done. I run my entire business on 30+ AI agents. They research, write, find leads, and do real work every day, and everything they produce flows into one shared brain I use to run the company. This is that system, start to finish. 🔗 TRY IT FREE Orbit — the operating system for Claude, Codex, ChatGPT and more. Free to start, no card needed.
