Features

Useful stuff for everyday typing

Auto-correction

Type a word and hit space. If it came out in the wrong layout, Boomkey rewrites it on the spot. Auto-correction is in beta and covers English and Ukrainian.

Hotkey & last word

Double-tap Shift, or set your own shortcut, to convert selected text between any two installed layouts: a word, a sentence, or a whole paragraph. Your clipboard is restored right after. Nothing selected? It fixes the last word you typed.

Per-app rules & exceptions

Turn Boomkey off or pin a layout in specific apps, and keep a list of words it should never touch. Terminals and code editors are off out of the box.
