+# LLM Wiki Pattern
+
+## Core Idea
+A pattern for building personal knowledge bases using LLMs. The LLM incrementally builds and maintains a persistent wiki - a structured, interlinked collection of markdown files that sits between you and the raw sources.
+
+## Three Layers
+1. **Raw Sources** - Immutable collection of source documents (articles, papers, images, data files)
+2. **The Wiki** - LLM-generated markdown files (summaries, entity pages, concept pages, comparisons, overview, synthesis)
+3. **The Schema** - Document that tells the LLM how the wiki is structured, conventions, and workflows
+
+## Operations
+- **Ingest** - Read source, discuss key takeaways, write summary page, update index, update relevant entity/concept pages, append entry to log
+- **Query** - Search for relevant pages, read them, synthesize answer with citations
+- **Lint** - Periodically health-check wiki for contradictions, stale claims, orphan pages, missing cross-references
+
+## Indexing and Logging
+- **index.md** - Content-oriented catalog of everything in the wiki, organized by category
+- **log.md** - Chronological append-only record of what happened and when
+
+## Benefits
+- Knowledge is compiled once and kept current, not re-derived on every query
+- Cross-references are already there
+- Contradictions have already been flagged
+- Synthesis reflects everything read
+- Maintenance burden is near zero (LLMs don't get bored)
+
+## Tools
+- **qmd** - Query Markup Documents: on-device search engine combining BM25, vector semantic search, and LLM reranking
+- **Obsidian** - IDE for browsing and editing wiki
+- **Marp** - Markdown-based slide decks
+- **Dataview** - Run queries over page frontmatter
