About this extension
A browser extension that autocorrects your misspelled words as you type, fast, private - Key Correct
🚀 Fast, Offline Autocorrect: All auto corrections happen locally on your machine, Every word you type is checked and corrected the moment you hit Space. no server calls, no waiting. This makes the extension incredibly fast.
🔙 Revert on Backspace: If you don't like the new corrected word, you can undo everything by hitting backspace.
⌨️ Keep Your Hand on the Keyboard: No need to search for word spellings on Google and copying pasting, (though you'll still sometimes need to do this, but way less)
🌐 Works Almost Everywhere: From drafting important emails in Gmail to collaborating in Notion, chatting on Discord, writing articles on Medium.
🤖 Adaptive Learning: Over time, Key Correct adapts to your writing style, vocabulary, and frequent corrections, the more you type the better it will become at correcting your typos.
✨ Custom Text Expanders: They actually save a lot of time for example you can create a text shortcut for "/email" to instantly expand it to an "email template" or your own email address ([email protected]), and of course it's the core functionality of keycorrect (replace incorrect word with the corrected word).
🍺 No Registration: yuppp that's correct.
🔒 Let's talk about privacy:
Everything is processed locally on your machine and no data leaves your computer. Simple.
(it's similar Alphabet's Google's Android's Gboard but for PC. have a nice day)
