Most AI second brain setups fail because the vault isn't built for it. This covers the structure, linking scheme, and agent protocol that actually make it work.

With the building a Second Brian boom, a lot of people have started opening Obsidian for the first time recently. If that is you, welcome. The app is free for personal use, but it has a learning curve that is steeper than most note-taking tools, and the documentation assumes a level of familiarity that can make the first few hours genuinely bewildering. This guide covers the foundations: what Obsidian is, why people use it, and the core concepts you need to understand before

There's been a lot of excitement recently around building a 'Second Brain' using Claude and Obsidian. Unfamilliar? Read my Claude Code or Obsidian Guides. Just make sure you come back and finish this article after :) For those who missed it, this idea was popularised by Andrej Karpathy and involves building a Wikipedia-style set of interconnected notes which can then be navigated and searched by AI agents. This means that we don't have to provide AI agents the same context ov

I built an AI-powered task system in Obsidian using custom Claude Code skills. This covers context engineering, note types, and the morning briefing automation.
