This is by far the most accurate AI grader I've tested. I tested it by posting an essay on my AP Lang facebook group. Essentially asking other AP graders to grade the essay. I scored it a 1/3/0, cograder scored it as a 1/3/0, and the random AP teacher that volunteered to grade the essay scored it a 1/3/0. So that is pretty good. It gives far more feedback than I would. Especially considering how many essays I grade, so it's a huge improvement.
