Is it possible to get Grammarly checking system-wide on MacOS? As far as I know, Grammarly only works as a browser plugin or Microsoft Office plugin (maybe more). Grammarly is fantastic, but the need to copy and paste my work into a designated Grammarly field is beyond inconvenient. Even a menu bar icon with a checker would be more convenient. I mainly work with 3rd-Party apps on Mac that don't have a Grammarly plugin.
I like how on iPhone Grammarly is a keyboard extension that captures your spelling live as you type.
What are some alternatives if this is impossible?
