Ai Selection Assistant — Smart Floating Toolbar for Obsidian

Drag-select any text in Obsidian and a sleek floating toolbar appears. Translate, copy, search, or run custom LLM prompts — all without leaving your note.

中文说明

Why Selection Assistant

Obsidian is a powerful writing tool, but switching between apps to translate, search, or process text breaks your flow. Selection Assistant puts everything right next to your cursor — just drag, click, done.

Each button shows the first letter of its name in a white circle. Native to Obsidian, adapts to light/dark theme automatically.

Features

• Drag-select to trigger — no clicking, no double-clicking. Only appears when you intentionally select text
• Translate — Google Translate API, auto-detect → your target language
• Copy & Search — one-click copy to clipboard or open in Google/Bing
• Custom LLM skills — up to 5 skills powered by your own AI provider
• Provider presets — DeepSeek, OpenRouter, Ollama, or custom endpoint
• Fetch & test — pull model list from API, test connection before saving
• Reorderable toolbar — visible buttons + "⋯" overflow menu
• Right-click menu — Copy, Paste, Cut in context menu
• Dark mode — inherits Obsidian theme colors
