AI Grammar Check Keyboard

Type in any language and keep original wording. Checker detects language automatically and fixes spelling, grammar and punctuation in messages, chats, emails and notes.

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.
