PasteGuard is a privacy-first browser extension that protects you from accidental data leaks when  pasting sensitive information into AI chatbots, LLMs, and search engines. It can be configured to detect patterns like API keys, emails, credentials, and replaces them with safe dummies before they leave your device.

Why install PasteGuard?

🔒 Data Leak Prevention – Stop exposing secrets to AI tools, forms, and shared platforms.

⚙️ Custom Rules – Define literal or regex-based replacements; trigger on copy or paste.

🧠 Smart Field Detection – Automatically allows safe pastes in login, OTP, or password fields.

🛡️ Guarded Sites – Enable protection only where you need it, while trusted sites stay unaffected.

🧩 Local &amp; Private – All processing happens on your device — nothing ever leaves your browser.

Ideal for:
Developers handling API keys, professionals sharing client data, or anyone who values clipboard privacy.

PasteGuard works transparently across all websites, with minimal permissions and zero tracking.
