QWERTY? AZERTY? SWAPERTY!
Typed it on the wrong keyboard?
Stop retyping. Start swapping.
Select the garbled text and switch your keyboard like you always do. Swaperty rewrites it instantly, in the right language. It works with every keyboard installed on your machine, even the ones you add later.

Sound familiar?
Two paragraphs of gibberish.
You were typing away, eyes on the keys. You look up and the keyboard was still in the other language. So you delete everything and type it again. And tomorrow it happens again.

Questions, answered
Does my text ever leave my computer?
No. Swaperty is 100% offline. The conversion is a mechanical mapping between keyboard layouts, computed on your machine. Nothing is uploaded or logged, and no AI reads your words.
Which languages does it support?
All of them. Swaperty converts between the keyboards installed on your machine, whatever they are: Spanish, French, Russian, Hebrew, Arabic, Hindi, Greek, Turkish and the rest. If Windows can type it, Swaperty can fix it.
Only to and from English?
No, between any two of your keyboards, in both directions. French to Hebrew works just as well as Spanish to English.
How does the 7-day demo work?
Download, run, done: every feature works for 7 days, without a card and without an account. When it ends, the app simply waits for a license key.
Lifetime or yearly, what's the difference?
Lifetime ($21) buys today's version forever, with security fixes. Yearly ($8.85) always has the newest features and priority support, and you can cancel whenever you like.
How do I cancel the yearly plan?
In two clicks, no questions: every receipt email from Lemon Squeezy contains a link to your customer portal, where a Cancel button stops future renewals. Your license keeps working until the end of the paid year.
Does it handle other languages, not just French?
Yes. Swaperty converts between any keyboards installed in Windows, and it understands each language's quirks (German's y/z swap and umlauts, Spanish ñ, Italian and Portuguese accents, Russian, and more), whichever way you convert. Auto-detection recognises the language from the text itself.
What about numbers and punctuation?
Letters, accents and most punctuation are restored, including “:”, “!”, “?” and doubled marks glued to a word. Real numbers (two digits or more, like 12/07 or a year) and the keypad symbols + - * are kept as-is. One honest limit: a lone period or digit can come from either the main row or the numeric keypad, and once text is on the clipboard nothing records which key was used, so Swaperty applies the most common interpretation. It gets sentences right; an occasional stray symbol is a one-character fix.
Windows warns about an “unrecognized app”.
That's SmartScreen being cautious with new independent software. Click “More info”, then “Run anyway”. Each download's SHA-256 checksum is published on the download page.
