Executive Summary
Shipped · v1.4 PDF ↓

Give every student honest writing feedback — at the scale of AI.

Essay Helper is a Microsoft 365 Word add-in that reviews a student’s draft and coaches their citations from inside the document — and it is architecturally incapable of inventing a source. It coaches instead of ghost-writing, meets students where they already write, and it’s built, tested, and shipped today.

The problem

Feedback doesn’t scale; bad AI does

One teacher can’t give thirty students timely feedback on argument and evidence. Generic AI fills the gap — but it fabricates citations (misconduct) or just writes the essay (learning lost).

The solution

A coach that can’t make things up

It flags weak arguments and unsupported claims as comments anchored to the sentence, and coaches in six stances — from Socratic questions to direct, provenance-tagged answers.

Why it wins

Trust, enforced in code

A validation layer drops any citation that doesn’t point to a source the student supplied — so the no-fabrication promise holds even if the model misbehaves. Institutions can approve it because of how it’s built.

The ask

A green light to run a pilot with 2–3 design-partner classes this term, a short runway to a Google Docs client + teacher-facing analytics, and support to court the first institutional buyer. The build risk is behind us — this is now about putting a finished, safe product in front of students and turning real classroom use into the sales story.
