Captin Alternative: Caps Lock HUD for Mac
Captin is great, but Notchy brings similar functionality right to your MacBook's notch, and adds a clipboard manager, AI usage tracker, and 50+ other tools on top, for $0.
Why use Notchy instead of Captin?
- Sleek Caps Lock HUD
Never type in all-caps by mistake. Get a clean, native-feeling HUD notification right under the notch whenever Caps Lock is toggled.
- Zero idle cost
Notchy is event-driven, meaning the Caps Lock detector costs nothing in CPU when you aren't pressing the key.
- One app instead of dozens
Notchy does the job of Captin, plus window snapping, menu bar hiding, AI usage tracking, and much more, all without cluttering your system with single-purpose apps.
