Layouto types the long parts for you and quietly fixes the typos.

Layouto is a menu-bar app for macOS 13 and later that helps in every app where you type. It expands your text shortcuts into full phrases, corrects misspelled words with your Mac’s built-in spell checker, and converts a word typed in the wrong keyboard layout into the word you meant. It is available on the Mac App Store: free for 7 days, then a monthly or yearly subscription.

No. Layout detection and correction happen entirely locally on your Mac, and nothing you type is logged or transmitted. One thing is kept, on your Mac only: when you undo an automatic correction with double Shift, Layouto notes that word, and after three undos it stops correcting it. The words it has stopped correcting are listed in Settings, where you can remove them.

Layouto uses Accessibility purely for input assistance: catching a mistake at the moment it happens, not for anything broader. It watches which key you press (a key code, not your screen content) so it can tell when your typed word only makes sense under a different keyboard layout, then enters the correction as an ordinary delete-and-retype.

That’s the entire scope: Layouto never reads another app’s text, interface, or screen. The AXUIElement APIs that would allow that are never called in the app, and the App Sandbox blocks that kind of cross-app access regardless. Keys are buffered locally for the current word only and discarded the moment the word is finished; nothing is logged or transmitted, and the only thing kept on your Mac is a note of the words whose automatic correction you undid, so that a word you keep undoing stops being corrected.

This is assistive technology in the literal sense of the term. Cognitive and memory conditions, including ADHD and executive function disorders, often make it hard to reliably track which layout is active right now; Layouto takes over that job instead of asking anyone to watch for it themselves. For people with a motor impairment, the benefit is fewer actions: no manual delete-and-retype cycle, less repetitive strain on the hands. VoiceOver users and others with a visual impairment cannot see the small layout indicator in the menu bar at all, so the correction has to happen without ever requiring a glance at it. Dyslexia and other language-processing conditions make fast layout switching especially error-prone, and older users working across several languages carry that same cognitive load. Accessibility is what lets Layouto catch the mistake on their behalf, automatically, before it needs fixing by hand.

Yes. All correction runs without an internet connection.

Press Shift twice. That restores the original text, and pressing Shift twice again cycles through your enabled layouts.

You get 7 days of full access for free, followed by a subscription. You can manage or cancel anytime in your App Store settings.

Layouto supports 43 languages in three tiers.

Tier 1

Arabic, Bulgarian, Danish, French, German, Greek, Italian, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, Turkish, Ukrainian, Vietnamese: convert automatically to and from every other Tier 1 or Tier 2 language. Belarusian, Croatian, Persian and Serbian convert automatically too, with dictionaries built into Layouto.

Tier 2

English, Dutch: convert automatically from any non-Latin script (Cyrillic, Greek, Hebrew, Arabic…); converting into them from another Latin layout takes the double-Shift keyboard shortcut.

Tier 3

Armenian, Bengali, Czech, Estonian, Finnish, Georgian, Gujarati, Hebrew, Hindi, Hungarian, Icelandic, Irish, Kazakh, Lithuanian, Punjabi, Romanian, Slovak, Slovenian, Telugu, Uzbek, Welsh: manual conversion on request (double Shift), or download a Hunspell dictionary for your language (a .dic + .aff pair, e.g. from the LibreOffice dictionaries collection), put both files into ~/Library/Spelling, then log out and back in (or restart your Mac). On the next launch Layouto detects the real dictionary and enables automatic conversion, so Hebrew, for example, moves to Tier 1.

If the files came from a browser, clear quarantine in Terminal: xattr -dr com.apple.quarantine ~/Library/Spelling

Yes. Layouto relies on macOS’s built-in spell checking. Download a Hunspell dictionary for your language (a .dic + .aff pair, e.g. from the LibreOffice dictionaries collection), put both files into ~/Library/Spelling (Finder → Go → Go to Folder…), then log out and back in (or restart your Mac). On the next launch Layouto detects the real dictionary and enables automatic conversion.

If the files came from a browser, clear quarantine in Terminal: xattr -dr com.apple.quarantine ~/Library/Spelling.

The dictionary has to genuinely validate words, meaning it rejects nonsense. Between different scripts (Hebrew ↔ English), conversion turns on right away, and between languages that share a script, it turns on only if the layout has letters distinctive of that language (ä, ş, ї…).
