Fixes as you type
From the fourth letter, before you hit space. From then on you are typing in the right layout.
Mac app
Wrong layout? Already fixed
Qwerty Switcher retypes a word you typed in the wrong layout, Russian or English.
Example: the start of a word, “ghbd”, typed in the English layout, turns into Russian “прив”, and the phrase goes on in Russian: “привет, как дела?” (hi, how are you?)
One key, two letters. The app works out which one you meant.
how it works
Five moments from an ordinary day
- As you type
- Double Shift
- Terminal
- Learning
- Games
Each word is weighed against a 697,000-word dictionary, word frequency and neighbouring letters, so even words the dictionary lacks get fixed.
Double Shift
Select text and press Shift twice: the whole selection switches layout. With nothing selected, the last word does.
Leaves commands alone
Latin commands in the terminal stay as they are: the app looks at the language of the surrounding text.
Learns from your fixes
Correct a word by hand twice and it gets fixed on its own after that. Your corrections are stored only on your Mac.
Stays out of your games
Recognises a game and leaves your keys alone. Start typing text again and the mode switches off by itself.

privacy
Your text stays on your Mac
- Every word is analysed on the spot. No analytics, no keystroke logging.
- It goes online only with your permission: once a day it checks for updates and sends nothing about you.
- The verbose log is off. A report you send strips the key codes by itself.

install
Three steps to the first fix
-
Drag it to Applications
Open the DMG and move Qwerty Switcher into the Applications folder.
-
Open it the first time
The build is signed with a self-signed certificate, so macOS will warn you. On macOS 15 and later: System Settings, Privacy & Security, “Open Anyway”. On 13 and 14: right-click the app, Open.
-
Allow keyboard access
The app opens the right settings pane itself. Without this permission it cannot see key presses. No restart needed.
faq
Short answers
Does it work in Telegram, Slack and VS Code?
Yes. The fix is typed one character at a time, so it reaches Electron apps too, where batched keystrokes get lost. In terminals, Latin commands are left alone.
Which languages does it understand?
Russian and English layouts: a 697,000-word dictionary, word frequencies and letter pairs for both languages.
How do updates arrive?
Turn on update checks and auto-install in settings. Once a day the app fetches one file from this site, and permissions survive the update. If you install a new version from the DMG over the old one, macOS will ask for permissions again.
Why is it free, and where is the source?
No subscription, keys or trial. The source code is open on GitHub under the MIT licence.
What if it fixes the wrong thing?
Press ⌘⌥Z and the word goes back to how it was. A word you correct by hand twice gets remembered.
