 # Memex Chat — Obsidian Plugin
 
-Chat with your Obsidian vault using Claude AI. Semantic context retrieval, `@` mentions, thread history.
+Chat with your Obsidian vault using Claude AI. Semantic context retrieval, `@` mentions, thread history, local embeddings, and a related notes sidebar.
 
 ## Features
 
 - **Semantic vault search** — TF-IDF index over all your notes, no external API needed for retrieval
+- **Local embeddings** — optional on-device semantic search using `@xenova/transformers` (BGE Micro v2), fully offline after first model download
+- **Related notes sidebar** — panel showing the most similar notes to whatever you have open, ranked by semantic similarity + frontmatter links + shared tags
 - **Auto context** — relevant notes are automatically found and sent to Claude as context
 - **Context preview** — see and edit which notes are included before sending
-- **`[[Note]]` mentions** — reference specific notes directly in your message
+- **`@Notizname` mentions** — reference specific notes directly in your message with autocomplete
 - **Thread history** — chats saved as Markdown in your vault (default: `Calendar/Chat/`)
 - **Streaming responses** — Claude's answer appears token by token
 - **Source links** — every answer shows which notes were used
+- **Prompt buttons** — header mode buttons that extend Claude's system prompt (e.g. draft check, monthly review)

 |---|---|---|
 | API Key | — | Your Anthropic API key |
-| Model | claude-sonnet-4-5 | Which Claude model to use |
+| Model | claude-opus-4-5 | Which Claude model to use |
 | Max context notes | 6 | How many notes to retrieve per query |
 | Max chars per note | 2500 | How much of each note to include |
-| Auto retrieve context | on | Automatically find relevant notes |
+| Auto retrieve context | on | Automatically find relevant notes on send |
 | Context preview | on | Show context before sending |
-| Save threads to vault | on | Persist chats as Markdown |
+| Save threads to vault | on | Persist chats as Markdown files |
 | Threads folder | `Calendar/Chat` | Where to save thread files |
+| Send on Enter | off | Enter sends (vs. Cmd+Enter) |
+| Context properties | collection, related, up, tags | Frontmatter properties boosted in search ranking |
+
+### Embeddings (optional)
+
+| Setting | Default | Description |
+|---|---|---|
+| Use embeddings | off | Enable local semantic search instead of TF-IDF |
+| Embedding model | BGE Micro v2 | ONNX model for local inference |
+| Exclude folders | — | Vault folders skipped during embedding |
+
+When enabled, embeddings are computed locally (no API call) and cached in `<vault>/.memex-chat/embeddings/`. The model (~22 MB) is downloaded once to `<vault>/.memex-chat/models/`. Indexing progress is shown as an Obsidian notice. Obsidian Sync activity is detected automatically and indexing waits until sync is idle.
 
 ## Commands
 
 | Command | Description |
 |---|---|
 | `Memex Chat öffnen` | Open the chat panel |
-| `Memex Chat: Index neu aufbauen` | Rebuild the TF-IDF search index |
+| `Verwandte Notizen` | Open the related notes sidebar |
+| `Memex Chat: Index neu aufbauen` | Rebuild the search index |
 | `Memex Chat: Aktive Notiz als Kontext` | Ask Claude about the currently open note |
 
+## Related Notes Sidebar
+
+Opens in the right sidebar and automatically shows the top 10 most similar notes to the currently active file. Similarity is computed from:
+
+1. **Semantic embedding similarity** (cosine distance on 384-dim vectors)
+2. **+0.15 boost** for notes linked via `contextProperties` frontmatter fields (e.g. `related: [[Note]]`)
+3. **+0.05 per shared tag** (up to +0.15)
+
+Notes explicitly linked via frontmatter are marked with a **verknüpft** badge.
