Claude Code + Obsidian: My family’s AI brain | Scott Farrar

Scott Farrar is a math educator and parent who got tired of AI chats that drift and forget. So he built a household brain in Claude Code: a folder of Markdown files, viewed in Obsidian, that knows his appliances, warranties, insurance documents, and everything on his family’s to-do list. In this episode, Scott shows how he uses it to shop for car insurance, plan repairs, share the system with his wife, and put priority tasks and recent wins on a wall display. We also talk about AI and math learning, and why he wants AI to keep kids doing the thinking.

What you’ll learn:

1. Why he moved his home life from AI chat to Claude Code
2. What Claude told him to photograph first
3. How AI made him a sharper insurance shopper
4. The to-do file he keeps coming back to
5. How he and his wife share one household brain
6. Why his wall display has a “recent wins” section
7. How a flipped tutor gets kids to teach the AI
