Essay Grading FAQ
How does an AI essay grader work?

Can I customize the grading criteria?
Yes. You can set up your own rubrics so the AI grades exactly how you would, focusing on any specific goals.

Can I review grades before students see them?
Yes. You have full control to review every score and comment generated before releasing to students.
