@colinwalker I wish Grammarly were better, but it's also the best I've found for what it does. If it were even a basic Mac app that had some scripting or ability to open a document from another app and edit, it would be 100% more pleasurable to use than what they have.
@collin An app would be very useful but I'm okay with the web interface. Grammarly definitely seems to fit my style more than others I've tried but I am still selective in what suggestions I accept.
