Smart grammar assistant
Grammarly is a super grammar helper that is much smarter than the default ones in most applications. I use it all the time. I’ve quickly come to depend on its artificial intelligence to improve my grammar and find more than the obvious typos. It seems context aware. And it runs at the OS level, so it works in most apps such as Slack, email, Discord, Evernote, Twitter, Facebook, etc. (It does not work in Google Docs for me.) Right now the basic model is free. — KK
