CapslockMute is a macOS utility that allows users to mute themselves on video calls by pressing the Caps Lock key. It works with Zoom, Teams, and Tandem, providing a faster alternative to clicking mute buttons or using keyboard shortcuts.

The key features include instant mute functionality where pressing Caps Lock toggles mute without hunting for buttons. It is signed and notarized by Apple with no Gatekeeper warnings, and runs silently in the background with no CPU impact.

The product works by listening for the Caps Lock key press and sending the mute shortcut to the selected meeting software. It requires Accessibility permission to detect the Caps Lock key but does not connect to the internet or collect any data.

Benefits include making muting and unmuting muscle memory, allowing quick responses to situations like sneezing, dictating notes via Aqua Voice, children making noise, or loud external sounds. It eliminates the need to search for mute buttons during calls.

The target users are macOS users who frequently participate in video calls on Zoom, Teams, or Tandem. It requires macOS 10.15 or later and conflicts with Karabiner-Elements key remapping software.
