Grammarly isn't even a very good tool. Many of the suggestions that it makes, takes a sentence or paragraph and completely changes the context. Another time I ran something I wrote through grammarly and it told me if I paid for the pro version it would tell me where the text was plagiarized from. I had just written it on the spot out of my own thoughts. I will never buy the pro version after it telling me my own thoughts are not my own. I like the Hemingway app when I have doubts about my grammar.
