How to select text in any Mac app and get instant AI rewrite suggestions via a keyboard shortcut

Overview

You are writing an email. You pause, read the last paragraph, and realize it sounds too aggressive.

To fix it, you highlight the text, copy it, open your browser, navigate to ChatGPT, paste the text, type a prompt asking it to soften the tone, wait for the response, copy the new version, switch back to your email, and paste it over the original text.

This process takes less than a minute. But when you do it twenty times a day, it breaks your focus.

There is a more elegant way to edit your writing. You can highlight text in any Mac app, press a keyboard shortcut, and get an instant AI rewrite without leaving your current window.

Here is how to do it.

The cost of context switching

The average knowledge worker spends more than a quarter of their workweek reading and writing emails. That is a lot of time spent staring at text, trying to find the right words.

When you struggle with a sentence, jumping to a separate AI app feels like a quick solution. But every time you switch applications, you pay a cognitive penalty. Research shows it takes an average of 23 minutes and 15 seconds to fully refocus after an interruption.

App switching is a structural problem. The solution is to bring the tool to the work, rather than moving the work to the tool.

Edit in place with WordPolish

WordPolish is a system-wide writing utility for macOS. It sits quietly in your menu bar until you need it.

Instead of treating AI as a separate chatbot, WordPolish treats it as a native extension of your keyboard. It works in Gmail, Slack, Notion, Word, and anywhere else you type.

Here is the workflow:

  1. Highlight the text you want to improve.

  2. Press the shortcut ⌘⇧X.

  3. Review the changes in the diff overlay.

  4. Press Enter to apply the polished text.

By keeping your hands on the keyboard, you maintain your momentum. Studies estimate that relying on keyboard shortcuts instead of a mouse can save you up to 64 hours a year.

Context makes the difference

When you copy and paste text into a generic AI tool, you lose the surrounding context. The AI does not know if you are writing a formal legal brief or a quick Slack update to your team.

WordPolish uses macOS Accessibility permissions to read not just your highlighted selection, but the text around it. It understands the flow of your document. It also applies your saved writing traits, ensuring the rewrite sounds like you.

You do not need to write a prompt. You just ask for a polish, and the system handles the rest.

Keep your focus

Writing is hard enough without fighting your tools. The next time you find yourself stuck on a sentence, do not open a new tab. Stay in your app, highlight the text, and let your keyboard do the work.
