AI Assignment Grader — LearnUpon pipeline

⚠ Internal — draft, do not publish

Case study details outstanding. The specifics on this page are placeholder pending the client’s confirmation of figures and wording. Do not publish until the real details are supplied — nothing here has been invented from data we don’t have.

The Problem

Manual marking that didn't scale.

Every submission was opened, read, and graded by hand — slow, inconsistent, and impossible to keep up with as course volume grew.

  • Every submission manually opened, read, and graded.
  • Turnaround times stretching to days.
  • Feedback quality varied between markers.
  • Resubmissions created duplicate workload.
The Workflow

From submission to feedback, hands-off.

6 stages
Webhook to feedback
Triggered by LearnUpon webhooks and run end to end with no human in the loop — feedback delivered in minutes, not days.
What It Does

3

Match rubric

4
