Agreement to Terms

Description of Service

Prompt Guard is a browser extension that detects potentially sensitive information in text you enter into AI assistant platforms. The Extension:

  • Scans text input for patterns matching sensitive data types
  • Alerts you before submitting prompts containing detected items
  • Offers options to redact, edit, or proceed with your submission
  • Operates entirely locally within your browser

Important: Prompt Guard is a tool to assist you in identifying potentially sensitive data. It is not a guarantee of complete data protection. You are ultimately responsible for reviewing and deciding what information to share with AI services.
