Embedding (Obsidian plugin)

Semantic, keyboard-first navigation for your vault. This plugin builds embeddings for your notes and opens a floating pop-out panel so you can jump through related ideas without touching the sidebar.

Currently supports OpenAI embeddings via an OpenAI API key.

What it feels like

• Open the pop-out and stay on the keyboard.
• a always opens the original note.
• b/c/d… open ranked similar notes.
• z recomputes using the currently open note as the new “original”.
• Hotkeys are captured while the panel is open, so focus changes do not break navigation.

Features

• Floating similarity panel (ESC closes it)
• Single-letter navigation with deterministic hotkeys
• Batch embedding updates for all notes
• Optional auto-update on startup (same logic as manual update)
• Configurable model, dimensions, and API base URL

MCP server (optional)

Enable the MCP JSON-RPC server in settings to expose semantic search over http://127.0.0.1:<port>/mcp. Tools: semantic_search_text, semantic_search_note, fetch_note.
