Kachunk

27 mechanical keyboards and real vintage typewriters for your Mac. Free forever with two packs — Kachunk Pro unlocks everything with one $4.99 purchase. No subscription. Every keystroke should sound like something. Kachunk lives in your menu bar and gives your Mac the voice of a real mechanical keyboard — or a 1938 Underwood typewriter. Every key you press, anywhere on your Mac, plays a mastered sound with natural per-strike variation. No two keystrokes sound identical. SOUNDS WITH SOUL • 27 sound packs recorded from real machines: Cherry MX Blues, Browns, Blacks and Reds (ABS and PBT), Topre, Holy Panda, NovelKeys Cream, Alpaca, buckling spring, and more • Real vintage typewriters: Underwood 1938, Olivetti Portable, and friends • Key-down AND key-up sounds for true mechanical feel • Typewriter flourishes: return bell, carriage slide, backspace strike • Subtle pitch and volume variation on every strike — organic, never robotic SMART WHERE IT MATTERS • Silence Kachunk in specific apps — never clicks in your meeting or screen share • Password fields are always silent, automatically • Optional auto-mute while music or video plays • Global mute hotkey (⌃⌥M) for instant quiet • Menu bar icon shows at a glance whether sound is on BUILT LIKE A MAC APP • Native, tiny, and fast — sounds play the instant a key goes down • Lives quietly in the menu bar; no Dock icon, no clutter • Launch at login and forget it's there (until you start typing) PRIVATE BY DESIGN Kachunk never records, stores, or transmits what you type. Keyboard events are used only to trigger sounds, entirely on your Mac. No analytics, no accounts, no data collection — nothing leaves your machine. FREE AND PRO The free version includes two full packs — the Underwood 1938 typewriter and NovelKeys Cream — plus every feature above, forever. One $4.99 purchase unlocks all 27 packs and every pack we add in the future. No subscription. Ever. Why type in silence?
