Muzzle

Muzzle is a Mac utility built to eliminate distractions during screen sharing or presentations. It automatically detects when you’re sharing your screen and silences all incoming notifications—emails, messages, app alerts—preventing accidental leaks of sensitive or irrelevant content. Customize which apps to mute, set exceptions for urgent contacts, or schedule quiet times (pro feature). Lightweight and unobtrusive, it runs in the menu bar for one-click toggling. Ideal for remote teams, educators, or public presenters, Muzzle keeps your focus on the task while securing your private information.
