この拡張機能について
Select any element or area on a webpage and instantly copy its full DOM structure + real CSS rules (from stylesheets) to clipboard – perfectly formatted for pasting into ChatGPT, Claude, Gemini, or any AI coding assistant.
Tired of describing layouts or copying messy “View Source” HTML? This add-on lets you point, click (or drag), and get clean, context-rich DOM + CSS ready for any LLM in one second.
Key Features
- Single-click element selection with live hover preview
- Drag-to-select rectangular areas (captures all elements inside)
- Automatically includes ancestor hierarchy up to <body> for proper context
- Extracts actual CSS rules from stylesheets (not just computed styles)
- One-click copy with customizable prompt template
- Visual overlay shows exactly what will be copied
- Full keyboard support (ESC to cancel)
How To Use
- Click the toolbar icon
- Choose Element Mode (default) or Area Mode
- Hover & click, or click-and-drag
- Formatted DOM + CSS is copied instantly – just paste into your AI chat
Output Example
Customization Options
- Ancestor levels (0–20, default 3)
- Children depth (-1 = all, default)
- Custom prompt template with {dom}, {css}, {url}, {timestamp} variables
- Toggle between single-element and area selection
Privacy First
- No data collection or transmission
- Only activates when you click the icon
- Runs entirely in your browser
- Settings stored locally
Best Practices for AI Use
- 2–4 ancestors = ideal context for most components
- 0 ancestors = when you want just one exact element
- Higher ancestors = debugging complex page structure
Works Everywhere
Tested on React, Vue, Angular, Shopify, WordPress, Tailwind, Bootstrap, and vanilla sites.
Instant DOM + CSS extraction for developers, designers, and prompt engineers on Firefox. Free, open-source, no tracking.
