title: Claude Code Can Be Your Second Brain
description: >-
  From time to time, we will republish episodes that you might have missed. This
  episode originally aired in September 2025. Noah Brier uses Claude Code as his
  second brain—it’s the coolest notetaking setup we’ve ever seen. He has Claude
  running on a server in his basement hooked up to a VPN. It stores, reads, and
  writes to thousands of notes in his Obsidian vault. He does it all from his
  phone. We had him on the show to tell us exactly how he’s pulling this off.
  Dan and Noah get into: The nuts and bolts of the Claude Code-Obsidian setup:
  Noah set up Claude Code on top of his Obsidian root directory, and he walked
  me through how he uses it to prep for an upcoming speech—creating a project
  folder, pulling in relevant research from his notes, saving transcripts from
  chats with other LLMs, and generating daily progress updates. The “thinking
  partner” that lives inside Noah’s second brain: Noah points out that in the
  hype around AI’s ability to write, the fact that it can read is overlooked.
  That’s why he has an agent inside Claude Code with strict guardrails to stay
  in “thinking mode.” It logs his questions, tracks insights, and catches him up
  on research if he returns to a project after a few days away. How Noah does
  deep work on his phone: Noah rigged a home server in his basement, put his
  Obsidian vault in it—and then runs Claude Code on top. Noah says that being
  able to think, write, research, and ship code from his phone has fundamentally
  changed the way he works. This episode is a must-watch for anyone curious
  about who wants to learn how to use Claude Code to build a true second brain.
