+# Automatic Tagging
+
+## Goal
+
+Suggest tags based on note content.
+
+## Approaches
+
+### Rule-based
+- Keyword extraction
+- TF-IDF
+
+### ML-based
+- Zero-shot classification
+- Fine-tuned model
+
+### Hybrid
+- Combine both approaches
+
+## Training Data
+
+Use existing notes with tags as training set.

+# Semantic Search
+
+## Current Search
+
+Keyword-based with scoring.
+
+## Semantic Search
+
+Use embeddings for similarity:
+- OpenAI embeddings API
+- Local models (sentence-transformers)
+- Vector database (Pinecone, Weaviate)
+
+## Implementation
+
+1. Generate embeddings for all notes
+2. Store in vector DB
+3. Query with user search
+4. Return top-k similar
+
+## Cost Analysis
+
+OpenAI: /tmp/generate_notes.sh.0001 per 1K tokens
+Local: Free but slower

+
+## Current Bottlenecks
+
+- Full re-index on file changes
+- No caching of parsed front matter
+
+## Optimizations
+
+### Incremental Indexing
+Only re-parse changed files.
+
+### Caching
+```go
