A Grammarly Keyboard alternative with no account

If you want grammar fixes, rewrites and translation built into your iPhone keyboard but would rather not create another account, GKeyboard works without one. There is no sign-up, email or password: install it, turn it on and type.

What you get without an account

Spelling, grammar and punctuation fixes as you type, in every app.
9 rewrite styles: Improve, Shorten, Expand, Formal, Friendly, Confident, Kind, Emojify, Fix grammar.
Translation into 22 languages.
Three ready-to-send reply suggestions when you copy a message.
Your own styles: describe how you want to sound and it becomes a one-tap button.
A real keyboard underneath, with autocorrect and word suggestions that run on your phone.

How it works with no account

When you first open the app it creates a random device ID. The GKeyboard server keeps a scrambled form of it, your phone's platform and when it last connected, your plan, and how many AI checks, rewrites and replies you used each day: counts only, never the text. That is what the free daily allowance runs on.

GKeyboard Pro is an App Store subscription billed to your Apple ID, so it needs no separate account either, and you can cancel it in your App Store subscription settings.

Good to know before you switch

GKeyboard is on iPhone today. The Android version is coming to Google Play.
AI features need Allow Full Access and an internet connection; the keyboard itself works offline.

Set up GKeyboard (about a minute)

Install GKeyboard from the App Store and open it. It is free and there is nothing to sign up for.
Open Settings → General → Keyboard → Keyboards → Add New Keyboard and choose GKeyboard.
Tap GKeyboard in that list and turn on Allow Full Access. iOS asks this of every keyboard that connects to the internet, and GKeyboard needs it to fetch AI suggestions. Without it you still get the keyboard, autocorrect and word suggestions.
In any app, touch and hold the globe key below the letters and pick GKeyboard.

The app walks you through the same steps when you first open it.

What happens to your text

There is no account: no name, email or phone number.
Autocorrect, word suggestions and spell check run on your iPhone.
With Full Access on, the text you are writing in the current field is sent over an encrypted connection to the GKeyboard server, which passes it to OpenAI to make the suggestion. That can be the whole message around your cursor, not just one sentence.
The GKeyboard server does not store that text and filters it out of its logs.
The AI switches off in password, email, URL, number, one-time code and credit card fields.
Turn off Full Access at any time and GKeyboard sends nothing; it keeps working as an on-device keyboard.
