Bilingual Switcher

Fix text typed in the wrong keyboard layout on macOS — like Punto Switcher, but for any language pair.

What it does

You meant to type in Russian, but the layout was English. Or the other way around. Don't retype — select the text, press the hotkey:

Demo: typing in the wrong layout in Slack, then fixing it with one hotkey

Works with any pair of installed keyboard layouts — not just English ↔ Russian. The app reads layout data directly from macOS, so there are no hardcoded mappings.

Install

Homebrew (recommended):

brew tap komandakycto/bilingual-switcher https://github.com/komandakycto/bilingual-switcher.git
brew install --cask bilingual-switcher

Or download the latest .dmg from GitHub Releases and drag the app to Applications.

Usage

Default hotkey: ⌥ ⌘ S — change it in Preferences.
Select text in any app, press the hotkey. The app auto-detects which layout the text was typed in and converts to the other.
Optional: enable “switch keyboard layout after conversion” so you can continue typing in the right language.
On first launch, grant Accessibility permission in System Settings → Privacy & Security → Accessibility.

Why

Any language pair — works with every keyboard layout that uses physical key mapping (English, Russian, Ukrainian, French, German, Spanish, Portuguese, Italian, Polish, Czech, Turkish, and more).
Works everywhere — Slack, VS Code, Safari, Notes, Terminal, JetBrains IDEs, contenteditable web fields.
Privacy — no telemetry, no data collection. Only network access is the optional Sparkle update check.
Lightweight — native Swift, no Electron. Universal binary, ~3 MB.
Open source — MIT licensed, source on GitHub.
