Build an Auto-Organizing AI Second Brain with Claude and Obsidian
blaizedsouza · x · 2026-08-01
The author shares how to build a "second brain" using Claude and Obsidian. Unlike typical chats that reset daily, this system acts as a self-filing cabinet: you drop information in, and Claude reads the entire context, categorizes it, and draws connections between related concepts.
Three core mechanisms make this work:
- Dynamic Interviewing: Instead of writing a manual profile, Claude interviews you one question at a time, saving answers to understand you progressively.
- Networked Notes: Every note points to others, eventually forming a knowledge map that surfaces forgotten connections.
- Data Ownership: Everything is stored as local plain text, allowing you to plug it into different AI models anytime.
