Use case

Users writing on Mac need to quickly fix grammar errors without switching apps or uploading to the cloud.

Users may use Grammarly web, Word's built-in checker, or manual proofreading.

Existing grammar checkers require copying and pasting to a web page or separate app, interrupting the writing flow, and may raise privacy concerns.
