LLM Privacy Shield

Chrome extension that intercepts and redacts sensitive data before messages are sent to LLM chat interfaces

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.
