CMD+C

On-the-fly grammar correction in any macOS app via a shortcut.

Desktop appfreemiumglobal

A native macOS utility that applies grammar and punctuation corrections in place across any editable app, website, or terminal via a keyboard shortcut. It helps avoid switching into a separate editor by letting writers, Mac users and non-native English speakers run corrections in context, with options to use a personal OpenAI or Claude API key or a low-cost plan, customize prompts, review correction history with explanations, and export data.
