reLayout

A tiny open-source menu-bar app that instantly retypes text typed in the wrong keyboard layout.

Website: relayout.forfutdinov.com

Typed ghbdsn instead of привіт? Press the hotkey — the word you just typed, or a selection, is retyped in the right layout, and the system input source switches too, so you can keep typing. Works with any installed layouts, not a hard-coded pair. macOS and Windows.

Install

macOS:

brew install --cask vladforfutdinov/relayout/relayout

or download reLayout.dmg from the latest release and drag it to Applications (signed and notarized). On first launch, grant Accessibility: System Settings → Privacy & Security → Accessibility → enable reLayout → relaunch.

Windows: each release has an installer (reLayout-windows-<arch>-setup.exe) and a portable .exe for x64 and arm64. They aren't code-signed yet, so SmartScreen asks once ("More info" → "Run anyway"). No auto-update yet — download a newer release to upgrade.

Use

1. Select the mistyped text — or select nothing right after typing a word to fix that word.
2. Press the hotkey (default: tap Shift twice).
3. Press again right away (before typing or clicking anything else) to try the next layout, and once there's none left, to undo.

Only words in the wrong layout are converted: я сказал ghbdtn → я сказал привет. A word split by a layout switch is fixed too: ghj + switch + сто → просто.

Change the hotkey (combo, modifier tap, or tap sequence) in rL → Settings….

Auto-correct (optional, off by default)

Fixes wrong-layout words as you type, no hotkey:

• Between Cyrillic and Latin layouts (ru/uk ↔ en/de/fr/es/pl/pt), judged by small on-device language models tuned for ≥99% precision.
• Experimental: between similar layouts of different languages (ru ↔ uk).
• Experimental: check with the system spelling dictionary — a real word is never converted into junk, a word the trigrams miss is converted when the dictionary knows its other-layout reading, and one typo inside a wrong-layout word is fixed when the dictionary leaves a single candidate (“ghbddtn” → “привет”). Off by default; uses the system's spell checker on macOS and Windows.
• Skips password fields. Per app you choose whether auto-correct and the hotkey work (Settings → Apps…); terminals, code editors, VMs, remote desktops and Figma start with both off.
• Leaves abbreviations alone: a word typed in capitals (IBM, МФЦ) is never auto-corrected — the hotkey still converts it.
• Learns from you: undo a fix (with the hotkey, or just erase it and type the word again — erase and retype a word it left alone to have it fixed again; or fix a word it missed by hand, and it remembers), or correct the same word with the hotkey a few times, and auto-correct follows your choice.
• Optional second hotkey to switch it on and off (Settings → Auto-correct on/off; not set by default). On macOS a dot in the menu-bar icon's corner shows it is on.

How it decides: ARCHITECTURE.md.

Privacy

• Your text never leaves the machine and is never written to disk. No analytics, telemetry, or account. The only network call is the update check: Sparkle on macOS (can be turned off), a look at the latest GitHub release on Windows (nothing is downloaded).
• The clipboard is left untouched when Accessibility can read the selection.
• Password fields are skipped. While macOS Secure Input is on (a password field or a terminal's Secure Keyboard Entry), the system blocks reLayout entirely.
• Only settings and auto-correct's learned words are stored (Settings → Learned words to view or reset).

Limitations

• Needs at least two keyboard layouts.
• Same-script layouts (e.g. ABC vs German) can't be told apart word by word.

Build from source

macOS — requires only the Command Line Tools (they include Swift; full Xcode works too). The app runs on macOS 13+; no Xcode project and no dependencies, build.sh calls swiftc directly.

xcode-select --install   # one-time: Command Line Tools
./scripts/make-cert.sh   # one-time: keeps the Accessibility grant across rebuilds
./scripts/build.sh       # -> dist/ReLayout.app

Windows — requires Visual Studio Build Tools (MSVC + Windows SDK) and the Swift toolchain (6.1+ on x64, 6.3.2+ on arm64). In PowerShell:

winget install --id Microsoft.VisualStudio.2022.BuildTools -e --source winget --custom "--add Microsoft.VisualStudio.Component.Windows11SDK.22621 --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.VC.Tools.ARM64"
winget install --id Swift.Toolchain -e --source winget
# reopen PowerShell so PATH picks up swift, then:
scripts\build-windows.ps1   # -> dist\win\ReLayoutWin.exe
