AI Physics Grader for Handwritten Answers
Proctor AI is an AI physics grader that reads a whole class of handwritten physics answer sheets and scores each against your rubric. Physics answers mix derivations, numerical working, units, and diagrams, so grading has to follow the method, not just the final number.
Upload one PDF, type a prompt or attach your marking scheme, and get every paper graded in minutes, with you in control of every result.
- 93% agreement with manual grading
- 10 sec average time per paper
- 97% less time spent marking

What grading physics involves
Physics answers combine worded explanations, formula derivations, numerical working with units, and labelled diagrams. A correct method with a unit slip should still earn most of the marks, and that is exactly how Proctor AI grades it.
What the Physics grader can grade
| Answer type | How Proctor AI grades it |
|---|---|
| Numerical working | Reads each step and awards partial credit, checks units |
| Derivations | Maps the steps to the expected derivation path |
| Diagrams | Recognizes labels in ray, circuit, and force diagrams |
| Conceptual answers | Scores against your rubric for point coverage |
| Graph questions | Checks axes, plotting, and interpretation |
- Numerical problems with step-by-step working and units
- Derivations of formulae and laws
- Ray diagrams and circuit diagrams
- Conceptual short and long answers
- Graphs and their interpretation
How it works
- Upload the class: Drop in one PDF of the answer sheets. The agent splits individual papers automatically.
- Set the rubric: Type a prompt describing how to grade, or attach your existing marking scheme.
- Let it grade: Each answer is read and scored against the rubric in seconds per paper.
- Review and approve: Check the marks and feedback, adjust anything, and approve. Nothing is final until you say so.
Frequently asked questions
Can AI grade physics answers?
Yes. Proctor AI reads handwritten physics answers, physics answers mix derivations, numerical working, units, and diagrams, so grading has to follow the method, not just the final number. It grades each against your rubric and you approve every mark.
Does it check units and partial credit in physics?
Yes. Proctor AI reads numerical working step by step, checks units, and awards partial credit for a correct method even if the final value is slightly off, exactly how you weight it.
How accurate is physics grading?
Proctor AI reaches around 93% agreement with manual marking, and because you review and adjust every mark, the final result is always teacher-approved.
Is the Physics grader free to try?
Yes. There is a free plan so you can grade a real set of papers before deciding.
