Built-in styles
Every built-in style preserves your meaning, facts, and point of view, and keeps the length close to what you said. Concise is allowed to shorten, but it still never drops a detail.
The AI cleanup page shows a live example for each style. You see the raw sentence (“we should meet tomorrow at ten, actually no, eleven, and go over the budget”) and how it comes out with the selected style.
Creating your own
The built-ins are fixed, but you can save any number of your own beside them. On the AI cleanup page, scroll to the Writing style section and choose New style.1
Name it
For example, “Calm and clean”.

Write the instructions
Describe how the wording should change. For example: “keep it casual and lowercase, and turn spoken emoji names into emoji.”
Your style never replaces the cleanup prompt. Both are sent to the model
together. The cleanup prompt decides what gets fixed. The style decides the
register of the result. They are independent.
