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 +--- +## Resources +**Repository:** https://github.com/svemagie/obsidian-memex-chat
