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 that helps you write clearly in any language you type. It detects the input language automatically, keeps your original language, and improves grammar, spelling, and punctuation without changing your meaning.
Use it where you already write:
Messages and chats
SMS and emails
Notes and quick drafts
What you can do in one flow:
Fix typos and spelling mistakes before sending
Improve grammar and punctuation for cleaner text
Rewrite sentences for better clarity and natural tone
Keep emojis and the intent of your original message
Multilingual by design:
Checker is built to process mixed real-world typing. You can paste or type text, run a check, and insert the improved version directly from the keyboard. The app focuses on correction and rewrite while preserving the language you used.
Custom prompts:
You can save your own prompts in the app and choose them from the keyboard. This helps you switch style quickly, for example concise, polite, professional, or casual.
Free and Pro:
Free access includes limited AI checks each month. Pro unlocks higher usage and supports longer text checks for heavier daily writing.
How to start:
Enable Checker keyboard in iOS Settings
Allow Full Access so AI checks can run
Open any app, type or paste text, and run a check
If you write across different languages, Checker helps you reduce errors and send clearer text faster, without leaving your keyboard.
Transform how you write. Download Checker and start improving your text for free.
