Fixes it from the very first word
Rekey reads what you typed in every installed layout and weighs each reading against language statistics and a dictionary. The moment you press Space, the wrong word is rewritten and the layout switched.
macOS Utility
Never type in the wrong language again

Fixed before you notice
Rekey works with words, not single keys: the moment a word lands in the wrong layout, it rewrites it correctly and switches the layout for you.
34languages
Not two languages — thirty-four
Most switchers know “English plus one”. Rekey tells 34 languages apart, from Ukrainian to Thai, and learned them from real text rather than hand-made word lists.
All languagesWhole phrases, not just words
A lone “f” says nothing. Rekey waits for the next word and fixes the whole phrase at once.
<200ms
Faster than you’ll notice
From Space to the corrected word in under 200 ms. Timing adapts for Slack and Discord.
Your text stays yours
Everything you type is analysed on your Mac and never sent anywhere. No account, no cloud processing. Below is the complete list of what goes online at all.
- What leaves your Mac
- What you typenever
- Update checkonce a day
- Anonymous crash reportscan be turned off
- Install signalonce
- Your emailonly if you gave it
And you stay in control
-
Undo with one keystroke
Within 5 seconds of a correction. Rekey remembers the word and leaves it alone from then on.
-
Your exceptions
Pin words that should never switch, or tie a word to a specific language.
-
Stays out of the way
Password fields, terminals and code editors are off-limits, so your ghbdtn in code stays exactly as typed.
-
Light and native
Pure Swift, no Electron. Sits quietly in the menu bar with a tiny CPU and memory footprint.
Get started in a minute
Three steps from download to your first corrected word.
1
Download and move to Applications
Open the DMG and drag Rekey into Applications. From then on the beta updates itself.
2
Grant Accessibility
The welcome window takes you to the right place in System Settings. Accessibility is required — without it Rekey can’t see your typing. Input Monitoring is recommended: it brings Rekey back instantly if macOS ever disables it. What you type still never leaves your Mac.
3
Turn on automatic correction
It ships switched off. On the last step of the welcome window, turn on “Correct wrong-layout words automatically” — until you do, Rekey corrects nothing.
How Rekey compares
Most layout switchers were built for one or two languages. Rekey was built for the way multilingual people actually type.
