Obsidian
A local-first markdown note-taking app with graph view, backlinks, and a rich plugin ecosystem.
Last updated: 2026-04-12
Overview
Obsidian stores all notes as plain .md files in a local vault — your filesystem is the database. This makes it ideal for the llm-wiki-pattern because Claude Code can read and write the files directly with no API or export needed.
The graph view visualizes backlinks between pages, making the knowledge structure visible. The more cross-references the LLM creates, the more useful the graph becomes.
Key Points
- All data is local markdown files — LLMs can read/write natively
- Graph view shows
[[wikilink]]connections between pages - Backlinks panel shows what pages reference the current one
- Dataview plugin enables SQL-like queries over your vault
- Templater plugin allows custom page templates
- Works offline; no vendor lock-in
Setup for LLM Wiki

/Volumes/mochidrive/second-brainas the vault root - Enable Core plugins: Backlinks, Graph view, Outgoing links
