Paper Checker

Grading handwritten exam papers with an LLM

Teachers upload the question paper, the answer key and a stack of scanned sheets. Evaluation comes back question by question.

01 Architecture

  • Gemini doing the evaluation against an uploaded answer key, on scanned handwritten sheets rather than typed submissions.
  • Four roles behind cookie based JWT auth, each with a different view of the same result set.
  • Results persist past the grading session, so teacher, admin and student all read from one record.
  • Node.js and React, with document processing in front of the model call.

02 What is in it

  • Question wise marks rather than a single total.
  • Handles the variation in handwriting quality that makes this hard.
  • Currently in build.
