Spots hidden instructions on web pages that try to trick AI assistants, and warns before you share private details. Works offline. Who is like God? Your St Michael guardian for everyday AI. Quisut helps you spot web pages that hide messages aimed at AI. More and more people ask AI assistants like ChatGPT, Gemini or Copilot to read, summarise or "help with" web pages and emails. Some pages hide text you can't see, such as white-on-white words, tiny text or notes tucked into the page's code. That text is written to trick the AI into giving you wrong answers, vouching for a fake website or asking for your passwords. This is called "prompt injection". WHAT IT DOES • Checks each page you visit for hidden text aimed at AI, and shows a clear, plain-English warning at the top of the page. • "Show me the hidden text" reveals exactly what was hidden. • Warns you on AI chat sites if you're about to send a bank card number, National Insurance number, bank details or a password. • Lets you paste an email or message into the shield's window to check it before you give it to an AI. • "This warning is a mistake" lets you mark a false alarm, and "Trust this site" turns the warnings for a site you know into a softer note. WHAT IT DOESN'T DO It doesn't block websites, read your email inbox, or change what AI tools say. It's a helpful early warning, not a guarantee. Some tricks, like cleverly reworded text, can still get through, so stay careful. YOUR PRIVACY • Works offline. All checking happens on your computer. • Nothing is sent to us or anyone else: no accounts, no analytics, no adverts, no tracking. • Your warning history (up to 90 days) and trusted sites are kept on your device, and you can clear them at any time.
