I built PISIGuard because I've been horrified at how much personal & sensitive information people (including myself) are feeding AI on daily basis. It is cumbersome to censor information by hand, so obviously very few do that at varying degrees of consistency. I wanted something practical that will hide personal & sensitive data, and of course without routing them through yet another server. So PISIGuard runs entirely in your browser. It spots names, email addresses, phone numbers, credit card numbers, passwords, API keys, and more, replaces them with safe placeholders, then puts the real values back into the AI’s reply. From your point of view, it’s mostly invisible; from the AI’s point of view, the sensitive stuff was never there. All detection, masking, and restoration happens locally. No data is sent to an external service. Nobody sees your messages but you and the AI, and the AI only sees the placeholders.
