Claude Code skills that turn an Obsidian vault into a self-organising AI second brain you fully own as Markdown.
What is claude-obsidian?
A bundle of Claude Code skills and setup scripts that turns an Obsidian vault into a self-organising AI second brain: drop a source (PDF, URL, note) and Claude extracts entities and concepts, creates cross-referenced wiki pages and maintains a knowledge graph of plain Markdown you own. It implements Karpathy's 'LLM wiki' pattern with hybrid retrieval (BM25 plus reranking) and PKM methodology modes (LYT, PARA, Zettelkasten).
Pros & Cons
Pros
- MIT with fully portable plain-Markdown data you own, no lock-in and no separate database or server
- Genuine engineering depth: 15 modular skills, hybrid retrieval, a test suite and active releases
- Runs inside tools users already have (Obsidian plus Claude Code)
Cons
- Locked to the Obsidian plus Claude Code ecosystem (needs a recent Obsidian for the full dashboard)
- An aggressive community and 'Pro' upsell funnel wraps the MIT repo
- Accuracy and interconnectivity numbers are self-reported and unverified

When it is interesting
Obsidian and Claude Code users who want an automated, self-linking knowledge base they fully own as Markdown.
When it is too early
If you do not use Obsidian or Claude Code, or need a turnkey hosted memory service rather than a vault you maintain.
