Questions and answers
Is Grammarly for Mac free?
Yes. The app and the basic grammar, spelling and punctuation checks are free with a Grammarly account. Pro adds rewrites, tone suggestions and plagiarism checks for a subscription.
Is Grammarly in the Mac App Store?
Only as a Safari extension. The desktop app that works in Mail, Word, Slack and other apps comes from Grammarly’s website, or install it with Homebrew.
Why does Grammarly need Accessibility access?
macOS lets an app read and change the text you type in other apps only with this permission. Without it, Grammarly can’t show suggestions. You can turn it off at any time in the same place.
