Browser extensionfree

pisiguard is a free, open-source browser-only tool that redacts personal data before pasting into an AI chat, then restores it in the AI's reply. Pasting sensitive text into a cloud AI chat risks leaking names, emails, card numbers or passwords. Runs entirely in the browser: detects and replaces sensitive data with placeholders, then restores real values in the AI's answer, for anyone pasting sensitive text into cloud AI chat tools.
