Why Local Processing is More Secure

🔒 No Data Leaves Your Device

All text processing happens 100% in your browser. Your sensitive information never touches our servers or any external network.

⚡ Real-Time Processing

Text is sanitized instantly as you type. No delays, no waiting for server responses.

🛡️ Multiple Detection Methods

We use pattern matching for emails, IP addresses, API keys, plus custom keyword filtering for maximum protection.

📱 Works Offline

Once loaded, PromptShield works completely offline. No internet connection required for text sanitization.

Why you should never paste raw data into AI?

AI models like ChatGPT and Claude can memorize training data, potentially exposing sensitive information. For enterprise compliance (GDPR/CCPA/HIPAA), data must be de-identified before processing. PromptShield ensures your confidential emails, IP addresses, and API keys are removed locally before reaching AI servers.

How PromptShield works?

Using client-side JavaScript regex patterns, all text processing happens in your browser's memory. No data is transmitted to external servers. When you refresh or close the page, all processed data is immediately cleared. This zero-retention approach provides maximum privacy protection for sensitive information.
