# AgriciDaniel/claude-obsidian

Self-organizing AI second brain for Obsidian + Claude Code. Drop any source and Claude reads, links, and files it into one connected knowledge graph of plain Markdown you own. AI note-taking, personal knowledge management (PKM), and an open-source Notion alternative. Based on Karpathy's LLM Wiki pattern.

## What it is
A Claude Code plugin/skill system that turns an Obsidian vault into a self-organizing AI second brain. It captures sources, creates linked and source-cited Markdown notes, and answers questions from the vault's own evidence while keeping all files as plain Markdown you own.

## Use cases
- build an AI-powered second brain in Obsidian
- automatically organize notes and sources into a knowledge graph
- get grounded answers from my own notes instead of starting from scratch
- replace Notion with an open-source local-first knowledge base
- capture articles and documents and have AI link and file them
- manage personal knowledge with Claude Code
- keep a self-maintaining Obsidian vault with Maps of Content

## When to choose
- you use Obsidian and Claude Code and want AI-assisted note capture, linking, and retrieval
- you want a local-first PKM where your data stays as plain Markdown files
- you want source-cited, grounded answers from your own knowledge base
- you want an open-source Notion alternative built on a knowledge graph

## When to avoid
- you don't use Claude Code or an Agent Skills-compatible host
- you want a hosted, turnkey note app with no local setup
- you need real-time multi-user collaboration like Notion
- you prefer fully manual note-taking without an LLM agent
