Overview

claude-obsidian transforms your Obsidian vault into a self-organizing AI second brain, powered by Claude Code. This project meticulously captures any source material, enabling Claude to intelligently read, link, and file it into a connected knowledge graph entirely composed of plain Markdown files that you own. It's an AI-driven approach to note-taking and personal knowledge management (PKM), offering an open-source, local-first alternative to tools like Notion.

Key Features

• Local-First & User-Owned: Your knowledge vault remains a standard directory of Markdown, JSON, and source files. Data is not hidden in plugin caches or uploaded to the cloud without your explicit consent.
• Compound Knowledge Loop: Moves beyond simple text capture to a repeatable workflow of retaining sources, grounding claims with evidence, connecting learned information, and then making that knowledge actionable.
• Grounded Claims & Provenance: Every important claim is sourced, with detailed ledgers tracking authority, freshness, support, contradiction, confidence, and review state. Sources survive summaries, ensuring transparency.
• Rich Interconnectedness: Generates linked pages, indexes, Maps of Content, and Obsidian Canvas views, allowing for deep navigation and visual exploration of your knowledge.
• Intelligent Retrieval & Maintenance: Query your vault for grounded answers, retrieve information contextually, and maintain vault health through built-in linting for dead links, orphans, and more.
• Modular Skill System: Features 15 distinct skills for building and using your wiki, extending workflows (like autoresearch and web content defuddling), and providing reference functionalities.
• Methodology-Aware Filing: Supports multiple note-taking methodologies (Generic, LYT, PARA, Zettelkasten) for routing new notes without disrupting existing vault structures.
• Transactionally Safe Operations: All mutating operations are managed as recoverable transactions, ensuring data integrity and preventing silent overwrites.

Typical Use Cases

• Personal Knowledge Management (PKM): Build a dynamic, interconnected personal knowledge base that grows more useful with every interaction.
• AI-Assisted Research: Effortlessly ingest research papers, articles, and web content, with AI grounding claims and linking findings into a coherent narrative.
• Second Brain Development: Create a digital extension of your mind, capturing ideas, insights, and information in a structured, retrievable, and linkable format.
• Open-Source Notion Alternative: Leverage a powerful, privacy-focused, and extensible system for organizing your life and work, with complete ownership of your data.
• Content Synthesis and Summarization: Use AI to condense complex information, extract key insights, and generate summaries that are directly linked to their original sources.
