I think grammarly is a quite useful tool if you're submitting assignments or just sending an email. It corrects your spelling and grammar mistakes. Like for example, if you're missing a comma, it'll underline it red and all you have to do is click on it and it's fixed! Same with a word spelt wrong. It corrects it. Grammerly is great! The reason why I won't rate it five star is that it becomes sort of annoying sometimes. It would sometimes make mistakes and try to fix a word I spelt right. I would have to click that word and ignore it. Also, Grammarly Premium is sorta to expensive. If Grammarly could fix those issues I would rate it five star.
