CapslockMute is a macOS utility designed to remap the Caps Lock key to function as a mute shortcut for popular video conferencing applications including Zoom, Teams, and Tandem. Its main purpose is to provide users with a faster and more intuitive way to mute and unmute themselves during video calls by leveraging the conveniently located Caps Lock key.

The key features include instant mute functionality where pressing Caps Lock toggles mute without needing to search for on-screen buttons. It operates securely as it is signed and notarized by Apple, eliminating Gatekeeper warnings. The application is lightweight, running silently in the background with no noticeable CPU impact. It requires granting Accessibility permission on first launch to detect the Caps Lock keypress.

The product works by listening for the Caps Lock keypress and sending the corresponding mute shortcut command to the selected meeting software (Zoom, Tandem, or Meet). This approach transforms muting into a muscle memory action, making it quicker than clicking buttons or using key combinations.

Benefits include the ability to quickly mute in various scenarios such as when about to sneeze, dictating notes via voice while on a call, during household disturbances like a child's tantrum, or when loud noises occur nearby. It enhances productivity by reducing friction during video calls.

Target users are macOS users who frequently participate in video calls on Zoom, Teams, or Tandem. The tool requires macOS 10.15 or later and should not be used with Karabiner-Elements due to conflicts. It emphasizes privacy by operating entirely locally without collecting data or connecting to the internet.
