Be the teacher whose feedback
actually changes student work.

MarkMate gives every student the detailed, rubric-aligned feedback you’d write yourself — in a fraction of the time.

The marking problem you already know

It’s Sunday evening. You’ve got 28 essays to mark, each one needing feedback that’s specific enough that the student will actually read it, act on it, and improve. By essay 15 your comments are getting shorter. By essay 25 you’re writing things you’d be embarrassed to say out loud.

And when students finally get their work back — with the grade, the comments, the careful annotations you stayed up to write — most of them look at the number and move on.

There’s a better way.

How MarkMate works

Three steps. Under a minute.

1

Upload your task notification

Upload your rubric and marking criteria once. MarkMate reads it and builds the marking framework for your class.

2

Students submit their work

They paste text, upload a file, or photograph handwritten pages. MarkMate handles typed and handwritten responses.

3

Every student gets detailed feedback

Marks against every rubric criterion. Annotated strengths and improvements. Vocabulary coaching. Writing structure tips. And a private AI detection report — just for you.

Live Demo

Paste up to 500 words and watch MarkMate give feedback the way you would — if you had unlimited time.

This is what every student in your class could receive — before you’ve marked a single paper.

What Australian teachers are saying

My Year 12 Ancient History students used MarkMate before submitting their essays. The feedback on source integration was exactly what I would have written — and it flagged the same issues I'd been writing on papers all term.

Head Teacher HSIE

Western Sydney Public School

It catches things I don't have time to write on every paper: first person usage, vague vocabulary, retelling instead of analysing. Students actually read the feedback.

English Teacher

NSW Public School

I checked my Biology report before handing it in and went from a Band 3 to a Band 5. The vocabulary suggestions made the biggest difference.

Year 11 Student

NSW

My daughter struggled with essay structure and I couldn't help — I don't know the rubric. Now she checks her own work and actually knows what to fix. Her confidence has improved as much as her grades.

Cheryl, founder of MarkMate

Built by a teacher. For teachers.

Hi, I’m Cheryl. I’m Head Teacher Administration at a NSW secondary school, and I built MarkMate.

I built it because I was spending Sunday evenings marking Year 12 essays and writing the same feedback over and over — ‘avoid first person’, ‘this is retelling not analysis’, ‘use subject-specific vocabulary’ — while knowing that half my students wouldn’t read a word of it.

I tried ChatGPT. I tried templates. Nothing read the rubric the way I needed it to.

So I built something that did.

MarkMate is what I use with my own classes. It’s built for the NSW curriculum, hosted in Sydney, and student work is never used to train AI.

Annotated Work

The full response highlighted with green (strengths) and orange (improvements). Click any annotation for detailed, targeted feedback.

Handwriting Recognition

Upload or photograph handwritten student work. MarkMate reads it automatically. Ideal for in-class assessments, exam practice, and batch marking.

Subject-Specific Feedback

Tuned for 30+ NSW subjects across all 7 faculties: English, Mathematics, Science, HSIE, PDHPE, Creative Arts, and TAS. Each subject gets checks specific to its curriculum.

Writing Structure Coaching

PEEL and TEEL, suggested where relevant. Checks intro, conclusion, paragraph length, argument flow, and whether the response matches the directive verb (describe, evaluate, analyse, and more).

Mathematics

Checks mathematical working, reasoning, and notation, not just the answer. Flags missing steps, modelling tasks that don't interpret results in context, and incorrect use of mathematical terminology. Covers Years 7–12 including Extension.

AU English Spelling & Grammar

Checks spelling against Australian English standards and flags grammar issues like tense inconsistency, run-on sentences, and apostrophe errors.

Vocabulary Coaching

Weak words replaced with stronger alternatives. Subject-specific key terms suggested. Why each change matters.

This is the gap between what students submit and what they could submit — if they had a teacher available at 11pm the night before.

Before: Student's Draft

“I think the Persian Wars were really important because they helped Greece become united. The Greeks fought against the Persians and won which was good for them. Herodotus wrote about it and said that the Greeks were brave. The wars changed a lot of things and made Greece stronger as a country.”

Vague language throughout
First person ("I think")
Retelling, not analysing
After: With MarkMate Feedback

“The Persian Wars were central to forging a collective Greek identity, as city-states that had previously operated independently were compelled to unite against a common threat. As Herodotus documents in The Histories, the victories at Marathon and Salamis became foundational narratives of Greek resilience.”

Precise historical vocabulary
Source integrated into argument
Analysis of significance, not retelling
