Rekey vs Boomkey

Both fix text typed in the wrong keyboard layout on macOS. Boomkey is built around a manual fix — select text or press double-Shift — with automatic correction in beta; Rekey is built around automatic correction as you type.

Short version: Boomkey is centred on a manual fix: press double-Shift (or its App Store shortcut) and the selection or last word is converted, for any installed layout pair. Its direct-download version adds automatic correction on Space in beta, for English with Ukrainian, Belarusian, Hebrew or Russian. Rekey is automatic first: it detects the wrong layout as you type, across 34 languages, and is free. Choose Boomkey if you want to trigger fixes yourself; choose Rekey if you want correction to happen without a keystroke.

Boomkey comes in two editions. The Mac App Store edition is sandboxed and manual: select garbled text and run the Boomkey shortcut or the Services menu item. It is free for 10 corrections a day, with a one-time Pro upgrade ($7.99). The direct-download edition ($9.99 once after a 7-day trial, for up to two Macs) adds double-Shift fixing of the last word or selection, per-app rules and automatic correction on Space, which is labelled beta.

Rekey takes the opposite starting point. Its language engine scores every finished word against your installed layouts and, when a word lands in the wrong one, replaces it and switches the layout — with no shortcut. If a correction is unwanted, Cmd+Z within five seconds reverts it and Rekey leaves that word alone from then on.
