Rekey vs Boomkey
Both fix text typed in the wrong keyboard layout on macOS — but they work differently. Boomkey fixes a word when you press double-Shift; Rekey catches and corrects the mistake automatically as you type.
Short version: Boomkey is a tidy manual fixer — you press double-Shift to correct the last word. Rekey is automatic — it detects the wrong layout as you type and rewrites the word in under 200ms, across 34 languages. Choose Boomkey if you like triggering fixes yourself; choose Rekey if you want it to just happen.
If you only occasionally mistype the layout, a manual fixer like Boomkey is enough: hit double-Shift and the last word flips. But if you switch languages dozens of times a day, pressing a shortcut every time becomes its own small chore.
Rekey removes that step. Its language engine scores each finished word and, when it lands in the wrong layout, deletes and retypes it correctly — automatically. You stay in flow instead of reaching for a hotkey.
