AI Grammar Keyboard for Android

Write clean, mistake-free messages in every app. SmartType fixes grammar, spelling, and punctuation across the whole sentence with one tap — not just one word at a time.

Grammar correction for whole sentences

Ordinary autocorrect works word by word, so it fixes typos but misses tense, subject-verb agreement, missing articles, and run-on punctuation — and it often changes the wrong word. SmartType uses AI that reads the entire sentence and rewrites it correctly while keeping exactly what you meant. Instead of “he go to work yesterday,” you send “He went to work yesterday.”

One tap, inside any app

Because SmartType is your keyboard, grammar correction is available everywhere you type: WhatsApp, Gmail, Outlook, LinkedIn, Slack, Instagram, notes, and browsers. Type your message, tap the grammar fix, and the corrected version replaces your text in place. There is no separate app to open and no content to copy back and forth.

Write with confidence at work and in a second language

Clear writing matters most when the stakes are high — a message to a manager, a note to a client, a job application, or a post you want taken seriously. It matters even more if you are writing in a language you are still learning. SmartType helps non-native English writers sound fluent and helps everyone avoid the small mistakes that slip out when typing quickly on a phone.

More than grammar

Grammar fix is one part of the SmartType keyboard. You can also change a message’s tone (professional, friendly, concise), generate a smart reply, or translate it into 369 languages before you send.
