HyperCaps transforms the Caps Lock key into a powerful productivity tool for macOS users. It repurposes what's described as "the least useful function" on the keyboard into a versatile "Magic Key" that enhances workflow efficiency without requiring complex configuration files.

The core features include turning Caps Lock into a Hyper Key that triggers Command+Option+Control+Shift simultaneously when held. It offers Vim Mode navigation using H/J/K/L keys without leaving the home row, and Smart Tap functionality where tapping Caps Lock provides Escape or Delete functions. Users can double-tap Caps Lock to access the original Caps Lock function when needed, and navigate with H/J/K/L (or W/A/S/D) while holding Caps Lock to avoid reaching for arrow keys.

The product works through a lightweight menu bar application that requires no heavy app windows. Settings can be changed directly from the menu bar icon, and a convenient HUD shows the current status at a glance. It includes customizable options for 3 or 2 key combinations in addition to the full Hyper Key functionality.

Benefits include eliminating "finger gymnastics" with complex shortcuts, improving typing speed by keeping hands on the home row, and providing global shortcuts that never conflict with other applications. A specific feature for Windows switchers allows remapping Command keys to Backspace/Delete for more familiar text editing.

The product targets macOS users seeking productivity enhancements, particularly Vim users who need easy Escape access, Windows switchers wanting familiar Backspace functionality, and anyone looking to optimize keyboard workflow. It requires macOS 13+ on Apple Silicon or Intel processors and operates 100% offline with native Swift performance.
