What an AI prompt privacy extension does.

An AI prompt privacy extension is a browser extension designed to reduce accidental sharing of sensitive data when using supported web-based AI tools.

Why prompt privacy matters

Many users paste customer data, personal information, financial identifiers, or secrets into AI tools without realizing how much raw data is in the prompt. A prompt privacy extension adds a browser-side layer before that message is sent.

How browser-side prompt protection works

  • The extension watches supported AI prompt fields inside the browser.
  • It detects sensitive values before the native send action happens.
  • It replaces those values with placeholders so the prompt remains usable.
  • The processed prompt is then sent directly to the AI service chosen by the user.

What users want from this type of extension

  • Local processing instead of an extra relay server.
  • Low-friction prompt protection that does not break workflow speed.
  • Coverage for PII, financial data, and common secrets such as API keys.
  • Clear privacy disclosures and user controls.
