AI Grading Tool: Grade Handwritten Papers, Essays and Exams With One Prompt
Proctor AI is an AI grading tool that corrects a whole class of handwritten answer sheets, essays, and exam papers in minutes. Upload one PDF of the class, type a plain-English prompt, and the AI grader reads each paper, scores it against your rubric, annotates corrections on the page, and hands you results to review and approve.
It is built for teachers who lose evenings to marking. A set of 40 descriptive papers that takes a full evening by hand is graded in minutes, with you in control of every mark. Start free, no setup required.

Frequently asked questions
What is an AI grading tool?
An AI grading tool reads a student's answer sheet, compares it to your rubric, and assigns a score with feedback, the same way a teacher would, but in seconds per paper. Proctor AI works as an agent you talk to in plain language: you upload the papers, tell it how to grade, and it marks the whole class while you stay in control of every result.
Can AI grade handwritten papers?
Yes. Proctor AI converts each scanned page into text using handwriting recognition tuned for messy classroom handwriting, understands which marks belong to which question, and grades each answer against your rubric. You review and approve every mark.
Is there a free AI grader?
Yes. Proctor AI has a free plan so you can grade a real set of papers before deciding. You can get started at no cost and upgrade later for higher volumes.
How accurate is the AI grading?
Proctor AI reaches around 93% agreement with manual grading in pilot testing, and the teacher reviews and adjusts any mark before finalizing, so the final result is always teacher-approved.
How long does it take to grade a class?
Most single papers grade in about ten seconds, and a full class of 100+ papers typically finishes in minutes, saving teachers most of their manual marking time.
