What is Aptype?
Aptype is an AI keyboard for iPhone and iPad. It sits where you already type, in Messages, WhatsApp, Mail, Slack, Instagram and almost any other app, and gives you AI writing tools one tap away: Grammar Fix, Rephrase, tone changes, Translate, Email and your own custom styles. Its signature feature, My Voice, rewrites text so it still sounds like you.

Only when you tap
Aptype reads the text in the field you're editing only at the moment you tap a tool. Your everyday typing never leaves your iPhone.
Not stored
Your text is sent to the AI, the result comes back, and neither is saved on our servers or used to train AI models.
Full Access, for one reason
iOS calls it Full Access. Aptype needs it only so the keyboard can reach the AI. It doesn't log keystrokes.
No account needed
No sign-up, no email, no password. Your voice profile and styles live on your device.
Set up in a minute
Three steps. Then just type.

FAQ
Questions, answered.
What is Aptype?
Aptype is an AI writing keyboard for iPhone. It fixes grammar, rewrites messages, changes tone, translates and writes emails inside any app you type in, such as Messages, WhatsApp, Mail, Slack or Instagram.
Is Aptype free?
Yes, Aptype is free to download and includes 5 free AI rewrites every day. Aptype Pro is an optional auto-renewing subscription that removes the daily limit and unlocks custom styles. Prices are shown in the app and on the App Store before you buy.
Does Aptype work in every app?
Aptype works in almost every app that shows the iPhone keyboard. iOS does not allow third-party keyboards in password fields and in some apps that block them, and in those places iOS switches back to the system keyboard automatically.
Why does Aptype need Full Access?
Full Access lets the keyboard connect to the internet, which it needs to send the text you choose to the AI when you tap a tool. Aptype does not send or store your everyday typing, and it never reads text unless you tap a tool.
Does Aptype store or read what I type?
No. Aptype only reads the text in the field you are editing at the moment you tap a tool, sends it for processing, and returns the result. We do not store your text or the AI's output on our servers, and we never use it to train AI models.
How is Aptype different from Grammarly or Apple Writing Tools?
Aptype is built around rewriting in your own voice. It learns how you naturally write from a short quiz, then rewrites, changes tone or translates without making you sound generic. It also works on iPhones that don't support Apple Intelligence (iOS 16.6 and later), and it keeps all its tools one tap away on the keyboard.
What is My Voice?
My Voice is Aptype's personal writing style. You answer a few quick questions, Aptype describes how you write (for example short, casual, lowercase, uses emojis) and saves that style on your iPhone. When you tap My Voice, your draft is rewritten to sound like you.
Which languages does Aptype support?
Aptype can translate between a wide range of languages. You pick the languages you write in during setup, and the Translate tool turns your text into the language you choose.
Which iPhones does Aptype support?
Aptype runs on iPhone and iPad with iOS or iPadOS 16.6 or later. It needs an internet connection for AI tools; the case tools work offline.
Is Aptype available on Android?
Not yet. An Android version is in development. Join the Android waitlist at aptype.dewmina.dev/android to get an email when it launches.
How do I cancel Aptype Pro?
Open the Settings app on your iPhone, tap your name, then Subscriptions, choose Aptype and tap Cancel Subscription. Cancel at least 24 hours before the renewal date to avoid being charged for the next period.
