Grammarly as a plug-in for Pages

I just realized that Grammarly is a plug-in for Microsoft Word. I certainly wish Apple would help Grammarly develop and publish a similar plug-in for Grammarly. For that matter, I'd like to see the same thing for ProWritingAid. I am a professional author, and I do significant self-editing before paying for a professional editor's help. My editing process is: ProWritingAid->Grammarly->Hemingway, with a final grammar/spelling run through Word or Pages or Scrivener depending on the platform I start with. I much prefer using Pages over Word. However, there are advantages of better handshaking between the other apps and Word, reducing the cut and pasting needed with Pages. If Apple would co-support development of plug-ins it would be awesome!
