Congratulations on adding GrammarlyGO; it's a game-changer and adds significant value when compared with similar apps :) Just one thing to point out: we are missing languages. I know that English accounts for nearly 59 percent of web content, but Spanish speakers need you as well.
My favorite Chrome extension is Grammarly. It is a grammar checker that helps me to improve my writing. Grammarly can detect grammar errors, spelling mistakes, and punctuation errors. It can also help me to improve my style and clarity.
I have used Grammarly almost daily for the last 6 years. It is one of the first apps I put on any new computer. I don't send anything to anyone without it it being checked by Grammarly first!
