Smart Copy — Dev Tools

About

Smart Copy — Dev Tools turns your clipboard into a developer Swiss Army knife.

Every time you copy text, Smart Copy instantly detects what it is — JSON, URL, color code, CSV, HTML, regex, JWT, Base64, email, IP address, or plain code — and offers one-click actions tailored to that type.


What it does:
• Detects copied content type automatically
• Shows a subtle on-page notification with the detected type
• Opens a popup with smart actions when you click the extension icon

Actions by type:
• JSON — Prettify, minify, generate TypeScript types, convert to HTML table
• HTML — Format/prettify, convert tables to JSON
• CSV — Convert to JSON
• Colors — Hex ↔ RGB ↔ HSL conversion
• Code — Format, minify, wrap in markdown code block
• URLs — Decode, extract query parameters
• Regex — Explain pattern in plain English
• Base64 — Decode to plain text
• JWT — Decode payload
• All types — Character/word count, UPPERCASE, lowercase, trim whitespace

Key features:
• Works with any copy method — Ctrl+C, right-click copy, and site copy buttons (ChatGPT, Stack Overflow, etc.)
• Chain actions — feed the result of one action into the next
• Undo support — revert any transformation instantly
• Zero permissions beyond clipboard read — no data leaves your browser
• Dark theme UI designed for developers

No account required. No tracking. No network requests. Everything runs locally in your browser.
