GrammarFix helps you correct grammar, rewrite, translate and draft wherever you type. Choose on-device Apple Intelligence or optional Cloud AI powered by GPT. Tap to fix grammar and spelling in Messages, Mail, Notes and other apps that support custom keyboards. Rewrite in styles such as Professional, Friendly, Concise, Polite, Confident and Funny, or use presets for X, Instagram and Threads. REFINE YOUR WRITING Preview a rewrite, then give another instruction before applying it. Cloud AI can suggest editing directions based on the draft. Apply when you are happy with the result, or cancel and keep your original text. Undo restores the original after a correction or rewrite. A BETTER KEYBOARD Type with spelling suggestions and optional auto-correction. Hold Delete to repeat, double-tap Space for a period, double-tap Shift for Caps Lock, or hold Space and drag to move the cursor. Optional haptics add feedback while typing. MORE WRITING TOOLS - Translate into 10 languages - Draft and refine text with AI chat - Send your draft from the keyboard into chat with Craft - Create custom rewrite presets - Save optional background and writing preferences for personalization YOUR CHOICE OF AI On-device AI uses Apple Intelligence and processes submitted text locally. It requires iOS 26, a supported iPhone and Apple Intelligence availability. Cloud AI is optional and off by default. Selecting it sends submitted text, recent chat context and enabled personalization to App City Studios and OpenAI. Cloud editing suggestions also send the current draft. Cloud AI requires internet, is subject to service usage limits, and requires Allow Full Access when used in the keyboard. Ordinary typing does not trigger cloud AI requests. Switch back to on-device AI in Settings at any time. See our privacy policy for processing and retention details. FREE AND PREMIUM Grammar fixes and a limited number of daily AI chats are free. Premium unlocks all writing styles, translation, emoji, custom presets, rewrite refinement and chat without the free daily chat limit. Cloud service usage limits still apply. Choose Lifetime, Monthly or Yearly. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage subscriptions in your Apple Account settings. Requires iOS 18 or later. Terms of Use: https://appcitystudios.com/eula Privacy Policy: https://appcitystudios.com/privacy-policy
