Mention Autocomplete

Type @ to instantly search and link any note in your vault — with full-text search, rendered preview, and smart sentence extraction.

Why

Obsidian's built-in [[ autocomplete only matches note titles. When you have hundreds of timestamped notes (250727_095442.md), finding the right one by title is impossible. You need to search by content — "which note was I talking about 早睡 in?"

@mention lets you type @早睡 and immediately see every note that mentions it, with the exact matching sentence highlighted, and the full note rendered in a side panel.

Features

• Full-text search across all markdown files (strips YAML frontmatter, indexes content)
• @ trigger — type @keyword anywhere in a note to see matches
• Rendered detail panel — hover or keyboard-navigate to see the full note body with markdown rendering
• Keyword highlighting — bright yellow highlights in both the suggestion list and detail panel
• Smart alias extraction — inserts [[note#heading|matching sentence]] bounded by sentence terminators
• IME-aware — correctly handles Chinese pinyin input; Enter confirms characters, then selects
• Keyboard-first — ↑↓ / Ctrl+N Ctrl+P to navigate, Enter to select, Esc to dismiss
• Click outside to dismiss
• Live index — automatically updates as you create, edit, rename, or delete notes

Usage

1. Type @ followed by any keyword
2. Navigate results with arrow keys or mouse
3. Press Enter to insert a wikilink — the alias auto-selects for quick editing

Install

From Obsidian Community Plugins

Search for "Mention Autocomplete" in Settings → Community Plugins → Browse.

Manual

Copy main.js, manifest.json, and styles.css into .obsidian/plugins/at-mention-autocomplete/.

Performance

Indexes are built in-memory at startup. For vaults with 10,000+ notes, initial indexing takes ~1-2 seconds. Subsequent searches are instant (O(n) substring match with scoring). File changes are debounced and incrementally updated.
