The AI Second Brain Blueprint
Two paths: Obsidian plus Claude Code on your laptop for $20/month, or build it for a client and charge $5,000. Both paths fully documented.
Two paths to the same destination. Path A: build an AI-powered second brain for yourself using Obsidian and Claude Code for $20/month, the cost of Claude Pro. Path B: build the same system for a client as a bespoke knowledge management system and charge $3,000 to $5,000. Both paths are fully documented.
How to do it
- 1Path A setup: install Obsidian (free), configure the Claude Code MCP to read your vault directory, define a daily capture and summary prompt
Why it works
The value of a second brain is compounding. A note from six months ago becomes the input to a decision today. Claude makes that compounding active instead of passive: it surfaces connections and relevant prior context that you would never find manually when you need them.
