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.

claude-obsidian is a Claude Code plugin that transforms Obsidian into an AI-powered personal knowledge management system with 15 coordinated skills. It processes sources into linked markdown notes with full provenance tracking, answers queries from vault evidence, and maintains knowledge graph health—all while keeping your data local in plain markdown files you own. The plugin implements a capture-ground-connect-use loop inspired by Andrej Karpathy's LLM Wiki pattern, supporting multiple PKM methodologies (LYT, PARA, Zettelkasten, Generic). Compatible with Claude Code, Codex, OpenCode, Gemini, Cursor, and Windsurf through the Agent Skills protocol.

Key Features

15 coordinated skills for wiki building, querying, ingestion, research, linting, Canvas creation, and CLI operations
Local-first architecture with content-addressed source preservation and full provenance tracking for every claim
Transaction-safe vault operations with SHA-256 approval hashes, atomic writes, and automatic rollback on conflicts
Multi-methodology support: Generic, LYT (Maps of Content), PARA, and Zettelkasten filing conventions
Source-grounded answers with explicit citation ledgers tracking authority, freshness, support, and contradictions
Deterministic BM25 retrieval with optional contextual embedding and cosine reranking
Obsidian Canvas integration for visual knowledge maps and graph exploration
Explicit network consent model—no automatic uploads, separate approval for web research and remote embeddings

Use Cases

  • 01Building a personal knowledge base from research papers, articles, and local documents with automatic linking
  • 02Creating a second brain for software development with source-cited technical notes and API references
  • 03Managing long-term research projects with provenance-tracked claims and contradiction detection
  • 04Converting scattered notes into a structured knowledge graph using LYT, PARA, or Zettelkasten methodologies
  • 05Querying existing vault knowledge instead of re-asking Claude the same questions from scratch
  • 06Maintaining vault health by detecting dead links, orphaned notes, stale indexes, and unsupported claims

It captures sources, creates linked notes with provenance tracking, answers queries from vault evidence, and maintains knowledge graph health while keeping all data local in plain markdown files.

How do I install the claude-obsidian plugin for Claude Code?+

Clone the repository, initialize a separate vault using the Python setup script with preview-and-approve workflow, then run Claude Code from your vault directory with the --plugin-dir flag pointing to the cloned repo.
