Building a $20/Month AI Second Brain Workflow with Claude
glenbeer · x · 2026-08-09
The author shares how to replace a $2,000/month human assistant with a $20/month Claude subscription by building an automated "second brain" workflow.
The system relies on three folders (raw/ for capturing information, wiki/ for structured linking, and output/ for generation) and a central CLAUDE.md file. Powered by three core prompts, Claude automatically reads the user's identity and historical context before each session, eliminating the need to repeatedly explain the background. Additionally, Obsidian's CEO shipped 5 skill files enabling Claude to natively integrate with Obsidian's syntax and workflow.
