How To Build an LLM Knowledge Base in Obsidian with Claude Code

Description

In this tutorial, you will learn how to create your own LLM knowledge base in Obsidian using Claude Code. Inspired by Andrej Karpathy’s LLM Wiki concept, this workflow turns Obsidian into a searchable second brain that you can query, expand, and maintain with the help of Claude Code.

🧠 What You Will Learn

• Karpathy’s LLM Wiki: the concept behind it
• Obsidian: set up your vault for an LLM knowledge base
• Obsidian Web Clipper: capture articles into your vault
• Claude Code: run it inside your Obsidian vault
• Knowledge base structure: folders, tags, and links that scale
