How to organize Obsidian notes for working with Claude AI

A user shared a folder structure in Obsidian designed to make Claude a more effective coding and work partner. It covers how to store prompts, project context, and reusable templates so you don't repeat yourself every session.

Obsidian is a note-taking app that saves everything as plain text files on your computer. This post proposes a practical folder layout for people who use Claude regularly — the goal is to give the AI enough background about your project without retyping it each time.

The setup separates system prompts (instructions that tell Claude how to behave), per-project context documents, and reusable prompt templates into distinct folders. For solo developers or makers who use Claude as a daily coding assistant, this kind of structure saves time and produces more consistent, higher-quality responses from the AI.

Key points

  • Organize an Obsidian vault with dedicated folders for AI collaboration
  • Store system prompts and project descriptions as files so you can reuse them instantly
  • Keep a library of prompt templates for common coding tasks with Claude
  • Having project docs and code notes in the same vault makes it easy to paste context into Claude
