I built a Chrome Extension to protect personal data from AI platforms

Hacker News

Hello HN, I built Caviard.ai, a Chrome extension to help protect personal data when using AI platforms like ChatGPT and DeepSeek. The extension automatically detects sensitive information — such as names, addresses, and emails — and replaces them before text is sent to AI services. You can toggle between the original and replaced values to ensure privacy. All processing is done locally, ensuring that sensitive data never leaves your browser. Why did I build it? I wanted a simple solution to use AI services without compromising my privacy, as I noticed that many platforms freely access personal data for model training and other purposes. I couldn't find a tool that offered this functionality, so I decided to create one. Feel free to try it out and share any feedback or suggestions! I'd love to hear what you think. Thanks! Damien
