AI Block is a free Chrome add-on developed by Papillon Software that enhances your browser's security by blocking all websites from calling the window.ai API. With the rise of on-device AI capabilities in browsers like Chrome's Gemini Nano, the potential risks of misuse have also increased. AI Block empowers users to control and prevent the use of window.ai, safeguarding against privacy breaches, unauthorized resource usage, data integrity attacks, and security vulnerabilities.

This tool offers complete blockage of the window.ai API, ensuring that no AI processes can run in your browser without your consent. It provides real-time protection by actively monitoring and blocking any attempts to access window.ai, all while working automatically across all websites.
