Protect Your Secrets with Secret Sanitizer

Secret Sanitizer is a free Chrome extension designed to enhance security when pasting sensitive information into AI chat applications. It automatically detects and masks sensitive data like API keys, passwords, and personal information before any of it reaches the chat interface. Users receive instant feedback on how many secrets have been blocked, ensuring a seamless experience while maintaining confidentiality. The extension offers customizable pattern controls, allowing users to specify what types of sensitive information to detect and mask, making it versatile for various use cases.

Privacy is a core feature of Secret Sanitizer, as it processes all data locally on the user's machine, eliminating concerns about data leaving the device. There are no tracking mechanisms or analytics involved, and the extension works fully offline. Ideal for developers and security-conscious users, this open-source tool is an essential addition for anyone regularly interacting with AI tools, ensuring that sensitive information remains protected.
