Cross-platform automatic keyboard layout switcher. Lives in the system tray, detects when you start typing in the wrong layout, switches it, and retypes the last word — like a friendly poltergeist that haunts your keyboard.
- Free & open source — MIT, pure Rust, no WebView.
- Private by construction — zero telemetry; typed words never reach the logs; exactly one network call exists (the update check) and one checkbox turns it off.
- Works where others don't — Windows, macOS, and Linux on both Wayland and X11.
