About

CopyMaster gives you multiple clipboard slots right in your browser toolbar — so you can store URLs, commands, prompts, API keys and any text you use daily, and copy them with a single click.

No more Ctrl+C → switch tab → Ctrl+C again. Everything you need is organized and one click away.

What you can do:
• Save unlimited slots across multiple colored tabs
• Auto-detect content type: URL, command, code, JSON, secret
• Mask sensitive data (API keys, passwords, tokens) with reveal toggle
• Pin important slots to the top
• Set expiry timers for temporary content
• Drag and drop to reorder slots
• Export and import your data as JSON backup
• Everything syncs across your Chrome devices automatically

Privacy first: All data is stored locally in your browser. Nothing is sent to external servers.

Free. No account. No tracking.
