The Problem

OSM platforms digitise the paper, not the teacher's thinking. Step-by-step partial credit still requires a full re-read — at scale, as slow as marking on paper.

The Solution

Sheldon reads the entire handwritten response — working steps, diagrams, final answer — using computer vision and OCR. An agentic pipeline maps each step to the rubric, awards partial credit where earned, and surfaces a draft gradesheet. The teacher reviews, adjusts if needed, and approves. Evaluation time drops from minutes to seconds per script.
