Mask This is a macOS menu bar application that uses Apple Intelligence to automatically detect and mask sensitive information in your clipboard in real-time.

Features

  • Real-time Clipboard Monitoring: Automatically detects when you copy text to your clipboard.
  • AI-Powered Masking: Uses Apple Intelligence to identify and hide sensitive data.
  • Privacy First: Processing happens locally on your device using on-device language models.
  • Menu Bar Integration: Quick access to settings directly from your macOS menu bar.
  • Customizable Notifications: Optional notifications to let you know when data has been masked.

Requirements

  • Apple Silicon Mac
  • Apple Intelligence enabled in System Settings.

How it Works

  1. The app runs in the background and monitors the system clipboard for changes.
  2. When a new text is copied, the app uses an AI to process the text and mask sensitive information.
  3. The masked text is written back to your clipboard.
