I like best about Grammarly is how it catches grammar mistakes and suggests better ways to improve my writing.
Most Helpful Critical Review
Verified User in E-Learning
I dislike that the feedback is minimal. I wish we didn't have to pay to see more in-depth feedback. I see it as a Google extension, and Google docs don't really have much when it comes to grammar and spelling check.
