AI Grammar Check Keyboard

Checker is an AI keyboard built to improve your writing while you type. It automatically detects the language of your input, keeps the original language, and fixes spelling, grammar, and punctuation without changing your intent.

Use it in the apps you already open every day:

Messages and chats

SMS and quick replies

Email drafts and work updates

Notes, comments, and short text edits

What you can do in seconds:

Correct typos before sending

Improve grammar and punctuation in one pass

Rewrite awkward sentences for better clarity

Keep your original tone and meaning

Preserve emojis and message style

Multilingual by default:

Checker is designed for real-world typing across languages. If you switch between English and other languages, the app processes text in the language you wrote. It improves your text instead of translating it.

Faster keyboard workflow:

Type or paste text

Run a check

Get an improved version

Insert it back into the app instantly

Custom prompts:

You can save custom instructions in the app and select them from the keyboard. This helps you quickly shift style depending on context, such as concise, professional, friendly, or direct.

Free and Pro:

Free access includes limited AI checks each month. Pro unlocks higher limits and supports longer text checks for heavier daily writing.

How to start:

Enable Checker in iOS Keyboards settings

Allow Full Access so AI checks can run

If you write messages, emails, and notes every day, Checker helps you send cleaner, clearer text without leaving your keyboard
