PasteGuard - Privacy Clipboard

Sharing text with AI shouldn't mean sharing your secrets. PasteGuard lives in your menu bar and masks sensitive data—emails, phone numbers, credit cards, and more—before you paste into ChatGPT, Claude, or any AI service. One shortcut, and your clipboard is privacy-safe. How about pasting logs without worrying about leaking client emails? Or sharing code snippets without exposing API keys? What gets masked - Email addresses → [EMAIL] - Phone numbers → [PHONE] - Credit card numbers → [CC] - IP addresses → [IP] - URLs → [URL] - Street addresses → [ADDRESS] - Your custom keywords → [CUSTOM] 100% offline. Your data stays put. No internet connection. No cloud uploads. No tracking. Everything happens on your Mac. How it works 1. Copy text (⌘C) 2. Mask it (⌃⌥⌘C) 3. Paste safely (⌘V) That's it. Three keystrokes. More features - Auto-mask mode for hands-free protection - Visual preview to see exactly what changed - Toggle detection categories on or off - Add custom keywords for project names, client codes, etc. - Runs quietly in your menu bar Perfect for - Developers sharing code with AI assistants - Professionals handling sensitive client data - Anyone who wants more control before hitting paste A note PasteGuard helps reduce accidental data exposure, but pattern-based detection isn't perfect.
