I'm so glad I subscribed to Grammarly. I used to have my husband proofread my posts. I have a serious issue with commas. The fact that I wrote and self-published my memoir, selling thousands of copies is nothing short of a miracle. I have a tenth grade education and earned my B+ english grade by writing in my journal. Tools like Grammarly make life much easier for a person like me. I'm not sure that I've gotten a score of 100. Sometimes Grammarly wants me to make changes that would take away from the story. It really doesn't like the way some Bible scriptures are written and I use them a lot. I have to hit the ignore or trash button for a correction often, but I love the program.
