For me the huge part of Grammarly's magic is that it's not just in the browser, but in any text input on desktop with their desktop app (with some exceptions). Having it only in only in one application just doesn't cut it, especially since it's not my browser of choice. Are there any plans regarding desktop integration. Linux is woefully underserved in this space with all major offerings (Grammarly, Languagetool) having only macOS/Windows versions.
I have developed a system-wide writing assistant like you're describing. By design, it has no exceptions to where it works.
Currently, it's only for Mac, but I'm working on an Electron version too (though it's quite challenging).
