I actually had to use something like this for a class in college… maybe 2 years ago? It was the worst thing. It would auto-grade, tell you your score, and how you could improve it. However, there was almost no way to actually respond to the grade. It would often tell you you didn't cover a specific topic, even when you had. There was no way of pointing out where you had discussed it, no way in the program of asking for a human review, anything. All this, of course, was exacerbated by the class being run by possibly the laziest professor I had all throughout college (all essays were graded by this, all tests in class were taken by clicker, all notes were Powerpoint slides provided by the book's publisher). Possibly, in the hands of someone who actually cared about teaching, a tool like this wouldn't have been so bad—but it seems to me that someone who cared about teaching would just grade manually to begin with.
