Prevent accidentally leaking secrets into AI chats.
PasteSafe protects you from accidentally leaking sensitive data when using AI tools.
When you paste text into AI chats like ChatGPT, Gemini, or Claude, the extension scans the content locally and detects sensitive information before it gets sent.
If something risky is found, PasteSafe can warn you or automatically mask it.
