PISIGuard: Protect your personal and sensitive info when you chat with AI

A new browser add-on called PISIGuard is pitching itself as the digital friend who grabs your phone before you overshare. Its whole gimmick is simple: when you type private stuff into an AI chatbot, it swaps out names, emails, phone numbers, passwords, and other sensitive details with harmless stand-ins before the message leaves your device. Then it quietly puts the real details back into the reply so everything still reads normally. The creator’s big selling point is that it all happens on your own computer, not on some mystery server.

But the real action was in the comments, where the crowd instantly split into Team “Finally, someone built this” and Team “Wait… who is doing this?” One skeptical commenter basically asked the question hanging over the whole launch: how do people “accidentally” dump personal information into AI in the first place? That hot take turned the thread from product demo into mini culture war about how careless people really are online. Others were more practical than dramatic, asking why the project doesn’t compare itself to rivals or why it only works in browsers when plenty of people now use AI through desktop apps and command-line tools.

Then came the classic internet comedy twist: one user said they wanted the same thing for hiding source code from AI companies… and, in perfect irony, admitted they were using an AI to build it. Another commenter popped in with a casual “some clients already do that automatically,” dropping a link like a mic. In other words: clever idea, real anxiety, and just enough side-eye to keep the drama flowing.
