CMD-C.app

CMD-C.app is a minimalist macOS app that corrects text in any application using a simple shortcut: press ⌘C three times. It removes the need to open a browser, paste text into online editors, or switch between windows—editing stays in your workflow.

How it works

Select text in any app and press ⌘C three times. CMD-C.app sends the selection to an AI model, fixes grammar, punctuation, and style, then returns the edited version.

Plans, flexibility, and privacy options

You can choose how to run corrections:

• Built-in premium plan starting at $2.99/month for 7,000 corrections
• Use your own OpenAI or OpenRouter API key (pay only your provider’s usage fees)

Who it’s for

CMD-C.app is useful for anyone who writes frequently on a Mac, including:

• Writers and editors
• Students
• Marketers
• Developers and product teams
