Rekey vs MLSwitcher
MLSwitcher switches the layout of selected text when you press a shortcut. Rekey detects the wrong layout automatically as you type and fixes it — no selecting, no shortcut.
Short version: MLSwitcher is shortcut-based — select text or press a key to flip its layout. Rekey is automatic — it watches what you type and corrects a wrong-layout word in under 200ms, across 34 languages. Pick MLSwitcher for deliberate manual control, Rekey for hands-off correction.
MLSwitcher is a dependable, established Mac App Store utility for switching layouts on demand. It works well when you know you mistyped and want to flip it yourself.
