One press. Four beats.
-
Type it the way it comes out.
No template and no prompt course. Half a sentence is enough to start.
-
Answer what it asks.
When something that matters is missing, it asks. Tap an answer, type your own, or skip.
-
Watch it land.
It adds the role, the details, the tone and the limits a good prompt carries, and marks every word it added.
-
Replace, insert or copy.
One tap puts it where you were typing. Refine it shorter or more specific, or undo and keep yours.
Where it works
On your Mac.
Select text in any app and press Command-Shift-E. A panel opens over what you were doing, improves the selection and puts it back.
macOS 12 or later. In beta.
On your phone.
A keyboard with Improve above the keys. Type or dictate in any app, in English or Spanish, and improve it before you send.
Android in beta. iPhone is next.
A photo needs light and a lens. Code needs tests. Each kind of prompt gets its own rules.
