LLM Privacy Shield

LLM Privacy Shield automatically detects and redacts sensitive personal data before you send messages to AI chatbots. HOW IT WORKS When you type a message containing sensitive information — emails, phone numbers, credit card numbers, addresses, or custom patterns — the extension replaces them with realistic fake data before the message leaves your browser. The AI gets a plausible response context without ever seeing your real data.
