The AI Grading Tool That Grades a Whole Class in Minutes
An AI grading tool reads a student's answer, compares it to your rubric, and assigns a score with feedback, the same way a teacher would, but in seconds per paper. Proctor AI is built as an agent you talk to in plain language: upload the papers, tell it how to grade, and it marks the whole class while you stay in control.
It handles handwritten answer sheets, typed work, MCQ, math steps, diagrams, and essays. A set of 40 descriptive papers that used to eat an entire evening is graded in minutes.
- 93% agreement with manual grading
