Writing with GrammarGem

Fixing text

The core loop: select, press the hotkey, done.

The fix hotkey is the heart of GrammarGem. Select any text in any app, press it, and your selection is corrected in place — grammar, spelling, punctuation, and clarity.

⌘;Fix the current selection

Because the grammar engine is deterministic and offline, the fix is effectively instant and works without internet. You can change the shortcut anytime in Settings → General.

Works where you work

Mail, Slack, Notion, Chrome, Messages, VS Code, and more. GrammarGem uses the Accessibility API where available and a universal clipboard fallback everywhere else.
