About:
Muzzle is a macOS utility that automatically suppresses notifications to prevent sensitive or distracting content from appearing during screen sharing. It provides a simple toggle to mute alerts from specific apps, ensuring a clean and professional presentation environment. This tool is essential for maintaining privacy and focus during video calls and live demos.

Key Features:

One-click activation to mute notifications
Blocks pop-ups from selected applications
Runs unobtrusively in the menu bar
Prevents accidental exposure of private information

Use Cases:

Screen sharing in professional video conferences
Live streaming or recording sessions
Presenting sensitive material in public spaces

Alternatives:

macOS Focus Mode – Built-in system feature that can suppress notifications but requires manual configuration and lacks a quick toggle for presentations.
Microsoft Teams / Zoom – These apps have a built-in 'Do Not Disturb' mode, but Muzzle provides a system-wide solution that works across all applications.
