Grade Coach's answer

Enzo, the founder, spent more than a decade teaching in international classrooms — RMIT, Scotch AGS, ISB, HCMC University of Science, plus partnerships with Hanyang University, Shandong UST, and Teach For America. The grading pile was killing his weekends.

He tried ChatGPT for nearly a full term before building anything. It worked — for a few papers. Then it drifted. Same essay scored differently on Tuesday vs Friday. Handwriting recognition was unreliable. The model would invent rubric criteria the teacher hadn't asked for.

The realization: general chatbots aren't built for grading consistency across a class set. A tool that locks the rubric, applies it the same way every time, and lets the teacher stay the final authority — that's what was missing.

Grade Coach started as a personal tool to grade his own classes. Then friends asked for access. Then schools. Now it's a complete teacher toolkit built on a shared substrate: every paper graded compounds into per-student concept-mastery maps that power worksheet generation, parent reports, and class analytics.

The founder still teaches the product the way he wished someone had taught him.

Grade Coach's answer

K-12 teachers grading rubric-based assignments, with a wedge focus on:

• International-school and ESL teachers — the founder's background. The product is designed around rubrics teachers set themselves, not around language fluency, so it doesn't penalize ESL writing patterns unless your rubric tells it to.
• Teachers who grade from photos — handwritten papers, phone uploads, mobile-first workflow. Most paid traffic lands on mobile, so the product is built around that.
• AP / IB / MYP teachers with complex multi-criterion rubrics where consistency across the stack matters most.
• Schools and departments piloting AI-grading at a per-teacher subscription rate — not enterprise-only, not a custom-quote sales motion.

Secondary audience: university instructors grading short-answer or essay work where rubric-lock matters more than question-grouping.

Grade Coach's answer

Three reasons, in order:

1. The teacher is always the final check. Every AI score and comment is shown to you for review and edit before anything is final. Other tools auto-submit; Grade Coach treats AI as a first pass, not the last word.

2. Private by default. Student work never trains any AI, never gets shared between teachers or schools. We don't sell student data. The privacy line is locked: student work stays between you and your students.

3. Consistency across the class. Where other graders treat each paper as a fresh AI prompt (and drift between them), Grade Coach locks the rubric on the first paper and uses that locked interpretation across the whole stack. The same essay would get the same grade if you re-ran it tomorrow.

The product is also honest about what it isn't. No AI detection (skeptical that it works reliably). No auto-submission. No chatbot pretending. Just rubric-locked grading that gives you your evening back.

Grade Coach's answer

The locked-rubric guarantee is the core mechanic. When you upload your first paper, Grade Coach locks the AI's understanding of your rubric, then uses that exact same locked interpretation for every paper in the class set. Paper 1 and paper 30 are scored against identical criteria — no model drift, no inconsistency.

A few other things that set it apart:

• Built by a teacher, not a tech team that consulted teachers later. The founder spent 10+ years in international classrooms.
• Mobile-first. Snap a photo of handwritten student work from your phone. Designed for a teacher with a stack of papers and a phone, not a desk and a scanner.
• You bring your own rubric — paste it, photograph it, or write it. No template, no wizard. Department rubrics, AP/IB, state standards, custom criteria all work the same way.
• One credit pool across grading, worksheet creation, parent reports, practice generation, and class analytics. Not separate seats for separate tools.
