Grammarly alternative · macOS
The Grammarly alternative for Mac that works in every app
Grammarly is great inside the browser — and frustrating everywhere else. If you write in the Slack desktop app, Apple Mail, Notion, Linear, or a code editor, Grammarly's checking often disappears. GrammaticAI takes a different approach: it works system-wide on macOS, so you can fix grammar, change tone, and translate text in any app with a single keyboard shortcut.
Why people switch from Grammarly on Mac
- Grammarly relies on a browser extension, so it doesn't help in most native Mac apps.
- It's a recurring subscription that can run $144/year or more.
- It can't translate between languages or let you pick your own AI model.
- Your text is processed on Grammarly's servers rather than going directly to an AI you choose.

How GrammaticAI works
Select text anywhere on macOS, press your global shortcut, and the improved version replaces your selection in about a second. Don't like it? Press ⌘Z to undo — it pastes natively, so undo just works. You can add a shortcut per language and switch between casual and formal tone on the fly.
