HyperCaps for macOS

Product Introduction

1. Definition: HyperCaps for macOS is a native utility (built with SwiftUI) that repurposes the Caps Lock key into a multifunctional productivity tool. It falls under the technical category of keyboard enhancement software, transforming an underused key into a dynamic modifier for streamlined workflows.
2. Core Value Proposition: HyperCaps eliminates inefficient "finger gymnastics" caused by complex keyboard shortcuts. It maximizes productivity by converting Caps Lock into a Hyper Key (triggering ⌘+⌥+⌃+⇧) and enabling Vim-style navigation, all while prioritizing privacy with zero data logging.

Main Features

1. Hyper Key: Holding Caps Lock instantly activates a four-key modifier combo (⌘+⌥+⌃+⇧), customizable to 2-3 keys. This creates conflict-free global shortcuts for apps like Photoshop or Final Cut Pro. Built natively in Swift, it ensures near-zero CPU usage (0.0%) and minimal memory (12MB).
2. Vim Mode: While holding Caps Lock, use H/J/K/L or W/A/S/D for cursor navigation, eliminating reliance on arrow keys. Ideal for coding in VSCode or text editing, reducing hand movement by 70% for home-row-centric workflows.
3. Smart Tap & Double Tap:
   • Single Tap: Sends Escape (essential for Vim/Neovim users) or Delete (configurable).
   • Double Tap: Toggles original Caps Lock functionality.
     Uses macOS event taps for low-level input interception, processed locally for privacy.
4. Menu Bar Control & HUD: Adjust settings via a lightweight menu bar icon (no resource-heavy windows). A real-time HUD displays active modes (e.g., "Hyper Key," "Caps Lock"), ensuring intuitive usage.
5. Windows-Style Deletion: Maps left/right ⌘ keys to Backspace/Delete, easing transitions for Windows switchers.

Problems Solved

1. Pain Point: Wasted prime keyboard real estate (Caps Lock) and inefficient modifier-key combinations causing slow, error-prone workflows.
2. Target Audience:
   • Vim/Neovim Developers: Replaces hard-to-reach Escape key with a tap.
   • Power Users: Streamlines app shortcuts in tools like Figma or Logic Pro.
   • Windows Migrants: Familiar Backspace/Delete mapping reduces retraining friction.
   • Accessibility Seekers: Minimizes finger strain via home-row navigation.
3. Use Cases:
   • Coding: Navigate code lines with H/J/K/L while holding Caps Lock.
   • Design: Assign Hyper Key + C to "Copy Style" in Figma.
   • Writing: Tap Caps Lock for instant text deletion (replacing ⌦).

Unique Advantages

1. Differentiation vs. Competitors: Unlike Karabiner-Elements (complex JSON configs) or Hammerspoon (scripting required), HyperCaps offers one-click setup via menu bar. Competitors lack integrated Vim navigation or Windows-deletion features.
2. Key Innovations:
   • Privacy-First Architecture: Zero data leaves the device (vs. cloud-based tools like Keyboard Maestro).
   • Resource Efficiency: SwiftUI-native build ensures ~12MB RAM usage and no battery drain.
   • Contextual HUD: Visual feedback for mode changes, absent in alternatives.

Frequently Asked Questions (FAQ)

1. Does HyperCaps work on older macOS versions?
   HyperCaps requires macOS Ventura (13) or newer, optimized for Apple Silicon and Intel.
2. Can I customize the Hyper Key modifiers?
   Yes! Assign 2–4 modifiers (e.g., ⌘+⌥ only) via the menu bar settings.
3. Is HyperCaps a keylogger?
   No. All processing occurs locally with zero external connections, adhering to strict privacy policies.
4. How does HyperCaps handle Vim mode in non-Vim apps?
   Vim navigation (H/J/K/L) works universally—in browsers, text editors, or spreadsheets—when Caps Lock is held.
5. What if I need the original Caps Lock function?
   Double-tap Caps Lock to toggle it on/off instantly.
