Grammarly is great if you need a simple grammar checker, you can't get software that's any better than it. However, I'm not gonna pay 30 bucks a month for a better version of the same software. It would also be amazing if they added English (Canadian) as one of the languages. As a Candian, it sucks to have to choose between American English and English. Overall, it's not bad. But you'll have to pay $30.00 if you want it to be great.
(I'm currently using non-premium Grammarly to write scripts for my YT channel and this very review. It fixed 7 mistakes in this review. So you get the idea.
