AI Keyboard for iPhone: How to Rewrite Messages With OneTap
You know what you want to say, but the message needs another pass. A customer reply sounds abrupt. A work update is too long. An email has the right information but still feels unfinished.
An AI keyboard brings writing tools into the keyboard area of your iPhone. With OneTap, you can work on a draft, request a revision, review the response, and insert it into a supported text field.
OneTap includes writing enhancements for rewriting, proofreading, shortening, and adjusting tone. It also supports saved AI prompts for instructions you want to reuse. Explore OneTap’s AI features
How to Rewrite Text With OneTap on iPhone
Begin with a short message so you can easily compare the original and revised versions.
Download OneTap. Visit the OneTap website and follow the app’s keyboard setup instructions.
Complete keyboard access setup. OneTap AI generation requires an internet connection and Full Access for the keyboard.
Open your draft. In an app that supports the OneTap keyboard, switch to it and open OneTap AI.
Provide the text. Type your draft into the AI prompt field. You can also use Use App Text to bring in selected text or available text from the active field. Check that the prompt contains the passage you intend to revise.
Choose an enhancement. Open Enhancements and choose an action such as Proofread or Make Concise to request the edit. For a custom instruction, write the instruction and source text in the prompt, then tap the up-arrow Generate button.
Review and use the result. Choose Copy to place the full response on your clipboard, or Insert to put it into the active text field. Check the insertion point or selection when replacing an existing draft.
The text available through Use App Text can depend on the destination app. Inspect the imported passage before generating, especially when working with a long message.
Choose the Edit Your Message Needs
A clear editing goal makes the result easier to judge. Start with the smallest change that would improve the message.
Proofread: Use this when the wording is already close and you want help with spelling, grammar, and punctuation.
Rewrite: Use this when the message needs clearer wording or a smoother flow.
Make Concise: Use this when the point is buried in repeated phrases or unnecessary explanation.
Make Professional: Use this when you want a more formal tone for a work conversation.
Make Friendly: Use this when you want the message to feel warmer and more approachable.
A professional message can still be short. A friendly message can still set a firm deadline. After generating, check that the edit kept the level of urgency and the meaning you intended.
Three Everyday Rewriting Examples
The following examples illustrate possible edits; actual AI results vary.
Shorten a project update.
Original: “Just wanted to give you a quick update to let you know that I’ve finished reviewing the draft and I’ll be sending my comments over this afternoon.”
Possible revision: “I’ve reviewed the draft and will send my comments this afternoon.”
The shorter version keeps the completed action and the timing. Those are the details the recipient needs.
Make a request friendlier.
Original: “Send the final images by Thursday so we can finish the page.”
Possible revision: “Could you send the final images by Thursday? That will help us finish the page on schedule.”
The request becomes warmer while keeping the deadline. Check that a tone adjustment does not accidentally make a required action sound optional.
Make a work message more professional.
Original: “Hey, I can’t make the call today. Can we do tomorrow instead?”
Possible revision: “I’m unable to attend today’s call. Would it be possible to reschedule for tomorrow?”
The revision changes the tone without inventing a reason for the absence. That is a useful standard for any rewrite: improve the wording while preserving the facts.
Give Custom Prompts Useful Boundaries
For a more specific edit, describe the audience, the desired change, and anything that must stay intact. For example:
Rewrite the message below for a customer. Keep it friendly and under 80 words. Preserve all dates, links, and commitments. Return only the revised message.
Add your draft beneath that instruction. Naming the audience and the details to preserve gives the request more direction than simply asking for “better” writing.
You can save reusable instructions as AI Prompt shortcuts. The main app’s OneTap AI library organizes saved prompts and folders; generation takes place in the custom keyboard on iPhone and iPad or the OneTap menu bar on Mac.
Review Before You Insert
Read the response once for meaning and once for details. Check names, dates, links, amounts, and promises. If the original says you will investigate a problem, the revised version should not promise that it will be fixed tomorrow.
Use Edit Prompt when the request needs more context. Copy lets you keep the response available for manual pasting, while Insert places it into the active field. Review the final message in its destination before sending.
Start with one everyday draft: a follow-up, a project update, or an email introduction. Download OneTap to bring rewriting tools into your iPhone keyboard.
