Grammarly is the best of the worst. I dislike them because they leave the third party cookies open and their extension is a security nightmare. However, they have nailed the user experience to a large extent. Most other tools (Pro-Writing Aid/Grade Proof) have a “shitty” user experience.
I am evaluating one another tool, and hopefully, I should be able to get a reliable alternative.
Stay tuned!
