Grammar Flow: AI Keyboard

Grammar Flow is an AI keyboard that fixes your grammar, types what you say, rewrites your tone and translates your text inside any app. Write mistake-free messages, emails and posts in WhatsApp, Gmail, Instagram, LinkedIn and everywhere else you type, all from one smart keyboard.

✨ FIX GRAMMAR IN ONE TAP

Tap Magic and the AI grammar checker corrects spelling, punctuation and grammar mistakes in your sentence instantly. No copy-pasting into a separate grammar correction app. The keyboard grammar check works in chats, emails, documents, forms and social media.

🎤 VOICE TYPING & SPEECH TO TEXT

Speak and Grammar Flow turns your voice into clean, correctly written text. Voice to text dictation supports 60 languages, so you can talk in English, Spanish, French, Arabic, Hindi and many more and get polished sentences typed for you. Faster than typing and great for long messages.

🎭 CHANGE TONE & REWRITE

Make any text professional, casual, polite, friendly, formal, direct or funny with one tap. The tone changer rewrites your sentence while keeping your meaning, so you can paraphrase a message before sending it to your boss, a client or a friend. Rephrase and polish text without leaving the keyboard.

🤖 ASK AI FROM YOUR KEYBOARD

A built-in AI chat assistant right on your keyboard, with 30+ ready-made AI writing assistants. Ask AI to write a reply, draft an email, create an Instagram caption, turn text into a tweet, humanize AI text or answer a question. Create your own custom AI assistants for the tasks you repeat every day.

🌍 TRANSLATE AS YOU TYPE

Translate your text into 75+ languages directly from the keyboard. Chat with anyone in their language: type in English, send in Spanish, French, German, Portuguese, Japanese, Korean, Chinese and more.
