ClarifierAI AI writing keyboard for iPhone and Chrome

What does ClarifierAI actually do?

ClarifierAI is an AI writing keyboard for iPhone and a Chrome extension from developer Daniil Pak. If you have typed a reply that sounds abrupt or has a few errors, you can ask it to fix the wording and put the revision back where you were typing. Start with a draft, choose what needs to change, and read the result before sending it. That makes it handy for short messages, personal emails, and web forms.

Fix a typo or rewrite the whole sentence

Choose grammar correction when the sentence already sounds like you and only needs spelling, punctuation, or grammar fixes. Use a rewrite or a tone adjustment when the problem is how the request comes across. For example, if you are asking to move a meeting, try making the wording more courteous and then check that the proposed day and time survived the edit. The iPhone app also offers dictation and custom writing actions. If you speak the first draft, check what the app transcribed before rewriting it.

Review individual edits in Chrome

In a field on a site such as Gmail or Notion, select the passage you want to edit. Open ClarifierAI with the button beside the selection, Alt+Shift+C, or the context menu. Pick an action such as Clarify, Shorten, or Grammar. The extension highlights its changes, lets you toggle individual edits, and replaces the passage when you confirm with the check mark. With no selection, the action applies to the entire field. Chrome Web Store listing

Set up the iPhone keyboard and translate a draft

Install the app, add ClarifierAI under Settings → General → Keyboard → Keyboards, and allow Full Access if you want to use its AI actions. In an editable field in Messages or WhatsApp, use the globe key to switch keyboards and choose the action on your draft. For a translation, check names, dates, and the intended level of formality before you send. The App Store lists iOS and iPadOS 17.6 or later. Secure fields can bring back the Apple keyboard, and individual apps can block custom keyboards. The developer lists Android on a waitlist. The App Store description lists translation into 113 languages. Check the target language in the app before relying on it for a recurring conversation. App Store listing

What happens to the text you submit?

The iOS policy says that when you request a transformation, the selected text and preferences go to a third-party AI service. ClarifierAI says it does not keep the text after processing, while the provider may briefly retain API data for abuse monitoring. The Chrome policy describes a separate path through ClarifierAI’s server to OpenAI when you invoke the extension. The iOS terms limit the app license to personal, non-commercial use and put responsibility for reviewing the output on you. iOS privacy policy · Chrome extension privacy policy · iOS terms of service

Questions about using ClarifierAI

Can I translate a WhatsApp reply while typing?

Yes. Write a reply in the WhatsApp text box, switch to ClarifierAI and translate the draft before sending. On iOS 18.4 and later you can also set the app as your default translator and use Translate on selected text.

Why does the iPhone keyboard need Full Access?

Its iOS keyboard needs network access to send the text you submit for processing. You can revoke Full Access in Settings, which disables the keyboard’s AI transformations.
