EssayGrader vs. Mentora: which AI grader fits your class?
EssayGrader is an AI essay grader: you bring the essays (uploads, scans or your LMS), choose or upload a rubric, and it drafts criterion-by-criterion scores and feedback you review. Mentora runs the whole assessment instead: you create the exam with AI, students take it in Mentora, and you get the grades and a debrief of what to reteach. Choose EssayGrader for essay-heavy writing classes; choose Mentora to give and grade tests in one place.
