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.

I'm undecided really. It's pretty good as far as the grading goes but, it's not the only AI service that does that(and other things as well). I think the yearly fee of $150 for a what amounts to a service that does grading is a bit steep. If it was say $7 a month, I'd seriously consider it.

Hi William, Thanks for your feedback. I appreciate your thoughts on pricing. Our $15/mo plan for unlimited grading reflects the high costs of AI and our focus on quality without big VC backing. We're aiming to be the best in grading accuracy and speed. I hear you on more affordable options. We're considering a lower-priced tier for teachers who grade less frequently. Your $7/mo suggestion is helpful as we explore this. We're always working to improve and value input from educators like you. Thanks for helping us make CoGrader better! Best, Gabe CoGrader Co-founder
