claude-obsidian

Claude + Obsidian knowledge companion. A running notetaker that builds and maintains a persistent, compounding wiki vault. Every source you add gets integrated. Every question you ask pulls from everything that has been read. Knowledge compounds like interest.

Based on Andrej Karpathy's LLM Wiki pattern. 11 skills. Zero manual filing. Multi-agent support. Optional DragonScale Memory extension (log folds, deterministic page addresses, semantic tiling lint, boundary-first autoresearch).

What It Does

Youtube Demo

You drop sources. Claude reads them, extracts entities and concepts, updates cross-references, and files everything into a structured Obsidian vault. The wiki gets richer with every ingest.

You ask questions. Claude reads the hot cache (recent context), scans the index, drills into relevant pages, and synthesizes an answer. It cites specific wiki pages, not training data.

You lint. Claude finds orphans, dead links, stale claims, and missing cross-references. Your wiki stays healthy without manual cleanup.

At the end of every session, Claude updates a hot cache. The next session starts with full recent context, no recap needed.

Why claude-obsidian?

Most Obsidian AI plugins are chat interfaces - they answer questions about your existing notes. claude-obsidian is a knowledge engine - it creates, organizes, maintains, and evolves your notes autonomously.
