AI Math Grader That Reads Working and Awards Partial Credit
Math is not graded on the final answer alone. Proctor AI is an AI math grader that reads handwritten working line by line, checks each step against the method, and awards partial credit, so a student who set up the problem correctly but slipped on arithmetic still gets the marks they earned.
It handles algebra, geometry, trigonometry, and calculus, including equations, fractions, and diagrams.
- Step-by-step working is read
- Partial credit awarded fairly
- 93% agreement with manual marks
- Minutes for a full class set
How the math grader scores working
- Read the working: Handwriting recognition reads equations, fractions, and symbols, not just the final line.
- Follow the method: The agent maps each step to the expected solution path.
- Award partial credit: Correct setup with a later slip still earns the method marks, per your rubric.
- Explain the deduction: It marks exactly where the error occurred so the student can learn from it.
