Memex Chat is an Obsidian plugin that lets you chat with your vault using Claude AI with proper context retrieval, not just keyword search.

||
What it does:
|
||
|
||
* 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.
