What is Tidy

Tidy is a Mac utility that fixes spelling and grammar in any app. Select text, press a shortcut, and the corrected version replaces it in place. A second shortcut rewrites text that reads as machine-generated. It runs on the model built into macOS, so nothing selected is uploaded, and @mentions, dates, and times are left untouched. Requires macOS 26 with Apple Intelligence.
