Show HN: Vigil – AI Chatbot Data Leak Mitigation in the Browser

As a developer I've caught myself copy-pasting large chunks of text into AI chatbot input fields. From time-to-time API keys, private URLs, etc. slipped through and probably baked into one of the nicest and shiniest models weights - forever. So I created a little browser extension that tries to mitigate such accidents by intercepting the pasted data and redacting it with structure-preserving but dummy values. The tool is heavily a work in progress, but I still find it useful, and only mildly intrusive. Enjoy!
