LLM Privacy Shield is a free Chrome extension designed to protect your sensitive information when interacting with AI chatbots. This tool automatically detects and redacts personal data such as email addresses, phone numbers, and credit card details before sending messages, ensuring that your real information is never exposed. It supports various platforms, including ChatGPT, Claude, Gemini, and Grok, making it versatile for users of different LLM chat interfaces.

The extension offers three operational modes: Automatic, which redacts information in real-time; Manual, allowing users to review redactions before sending; and Disabled, for times when the extension is not needed. With a strong emphasis on privacy, LLM Privacy Shield collects no data, operates entirely locally, and is open-source, providing users with confidence in their online interactions.
