+## Capabilities
 
-What it does:
+The plugin provides these key features:
 
-*   Semantic vault search: a TF-IDF index over all your notes, no external API needed for retrieval
-*   Local embeddings: optional on-device semantic search using BGE Micro v2, fully offline after one model download (~22 MB)
-*   Auto context: relevant notes are automatically found and attached to your query before it even reaches Claude
-*   @ mentions: reference specific notes directly in your message with autocomplete
-*   Context preview: see and edit which notes are included before sending
-*   Related notes sidebar: always-on panel showing the most similar notes to whatever you have open, ranked by semantic similarity, frontmatter links, and shared tags
-*   Thread history: chats saved as Markdown in your vault, renameable inline, so nothing disappears
-*   Message actions: copy any assistant reply or save it directly as a new note
-*   Source links: every answer shows which notes were used as context
-*   Prompt buttons: configurable header buttons that extend Claude’s system prompt (e.g. draft check, monthly review); date-mode buttons can pull in notes by date range instead of search
-*   System context file: a vault note you can pin to the system prompt — useful for personal context that should always be there
-*   Installation is manual for now: download main.js, manifest.json, and styles.css from the latest release, drop them into .obsidian/plugins/memex-chat/, enable in Community Plugins, and add your Anthropic API key.

+- **Semantic vault search:** TF-IDF indexing across all notes without external APIs
+- **Local embeddings:** Optional offline semantic search using BGE Micro v2 (~22 MB model)
+- **Hybrid search:** When embeddings are enabled, TF-IDF keyword ranking and local semantic embeddings are combined via Reciprocal Rank Fusion (RRF) — neither score space needs normalization, and results are better than either engine alone. Falls back to TF-IDF-only while embeddings are still indexing.
+- **Automatic context:** Relevant notes automatically attached to queries before reaching Claude
+- **@ mentions:** Direct note references with autocomplete support
+- **Active note command:** "Memex Chat: Aktive Notiz als Kontext" opens a new thread pre-filled with the current note as explicit context, asking Claude to explain and connect it with other vault concepts
+- **Context preview:** View and edit included notes before sending
+- **Related notes sidebar:** Always-visible panel showing semantically similar notes, ranked by similarity, frontmatter links, and shared tags
+- **Thread history:** Chats saved as Markdown in your vault with inline renaming
+- **Message actions:** Copy assistant replies or save them as new notes
+- **Source links:** Answers display which notes provided context
+- **Prompt buttons:** Configurable header buttons extending Claude's system prompt (e.g., draft checking, monthly reviews); date-mode buttons retrieve notes by date range
+- **System context file:** Pin vault notes to the system prompt for persistent personal context
+- **Manual installation:** Download main.js, manifest.json, and styles.css from releases into `.obsidian/plugins/memex-chat/`, enable in Community Plugins, add Anthropic API key
