In plain English
While you are typing on a Mac, this app can rewrite the selected text inside whatever program is open. It fixes grammar, changes the tone, or translates the sentence, and the AI does that rewrite. People pay a subscription because hopping into a separate chat just to fix a line breaks their concentration. The AI does most of the rewriting and the billing. The person running the app still checks quality, helps users, and looks at wording that should not be changed without a person.
