AI Grammatic is a native Mac app that rewrites selected text in any application using AI. Just select the text and press ⌘⌥E — it’s replaced in place in about a second. No copying and pasting into a chat window. It corrects grammar, adjusts awkward phrasing, and can translate between languages, all in one shortcut. The app supports over 30 languages, each with its own configurable shortcut. Add Shift for a formal version. Text is not stored: on the Free plan it passes through a server and is discarded; on the Pro plan it goes directly from your Mac to your own AI provider. Free plan gives 10 rewrites a day with no sign-up. Premium ($69/year) gives 50,000 words a day and lets you choose the AI model. Pro ($29/year) uses your own API key for unlimited rewrites.
