## What is Grammar Fix?

GrammarFix is the on-device AI keyboard that fixes your grammar, sharpens your writing, and keeps every word private.

Tap once to correct grammar and spelling anywhere you type - Messages, Mail, Notes, social apps, any text field. Need a different tone? Rewrite the same text as Professional, Friendly, Concise, Polite, Confident, or Funny. Translate as you type into 10 languages. Or open the built-in AI chat to draft and refine anything.

Everything runs on your iPhone using Apple Intelligence. No servers. No network. No tracking. Your words never leave your device - so you get powerful AI writing help without handing your text to anyone.

WHAT YOU CAN DO
• Fix grammar and spelling instantly, right from the keyboard
• Rewrite in any style: Professional, Friendly, Concise, Polite, Confident, Funny
• Add fitting emoji to your message with one tap
• Translate your text into 10 languages, on-device
• Chat with an on-device AI to write emails, notes, replies, and more
• Craft: send what you've typed straight into chat to refine it
• Save your own custom rewrite styles

PRIVATE BY DESIGN
GrammarFix processes everything locally with Apple's on-device models. Nothing you type is sent to a server or shared with anyone, ever.

FREE AND PREMIUM
Fixing grammar is free, forever — plus a few AI chats every day. Upgrade to Premium for every writing style, translation, emoji, custom presets, and unlimited AI chat. Choose a one-time Lifetime unlock or a monthly or yearly subscription (the yearly plan includes a free trial).

REQUIREMENTS
The on-device AI features need an iPhone with Apple Intelligence (iOS 26). On other devices, GrammarFix uses a lighter built-in spelling fix.

Subscriptions auto-renew unless canceled at least 24 hours before the end of the period; manage or cancel anytime in your Apple Account settings. Terms of Use: https://appcitystudios.com/eula - Privacy Policy: https://appcitystudios.com/privacy-policy
