The marking problem you already know
Every teacher knows the feeling. A stack of 30 essays to mark, each needing detailed feedback that students will actually read and use. It takes hours.
And students often don't know if their work is on track until they get the final grade back, when it's too late to improve.

Annotated Work
The full response highlighted with green (strengths) and orange (improvements). Click any annotation for detailed, targeted feedback.
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, TEEL, STEEL, TEE, suggested where relevant. Checks intro, conclusion, paragraph length, argument flow, and whether the response matches the directive verb (describe, evaluate, analyse, and more).
Vocabulary Coaching
Weak words replaced with stronger alternatives. Subject-specific key terms suggested. Why each change matters.
Handwriting Recognition
Upload or photograph handwritten student work. MarkMate reads it automatically. Ideal for in-class assessments, exam practice, and batch marking.
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.
AI Writing Detection
Teachers get a private AI detection report on every submission, with four risk categories and supporting evidence. Never shown to students.
See the Difference
What a student sees before and after checking their work with MarkMate.
“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.”
“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.”
What Teachers Are Saying
My Year 12 students used MarkMate before submitting their Ancient History essays. The feedback on source integration was spot-on, exactly what I would have said.
Head Teacher HSIE
Australian 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
Australian 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
Australia
My daughter struggled with essay structure and I couldn't help because I don't know the rubric. Now she checks her own work and actually knows what to fix. Her grades have improved and she's more confident.

Common questions
The things teachers and parents ask before they sign up.
Is it free?
Yes, to start. The free plan gives teachers 2 assignments per month and 10 student checks, or 5 self-checks per month for students. Paid plans for higher limits start at $7.99/month for students and $9.99/month for teachers. All prices in AUD, incl. GST.
How accurate is the marking?
MarkMate uses a premium AI model tuned for the Australian curriculum, instructed to mark the way a real teacher would. It's accurate enough to be useful as a draft check or first-pass mark, but it's a guide, not a final grade. Always defer to the teacher's professional judgement.
Does it replace teacher judgement?
No. MarkMate is built to save teachers time, not replace them. Grades and feedback are indicative. Teachers stay the final arbiters, and the platform is built around teacher-controlled assignments and rubrics.
Is this cheating?
No. MarkMate doesn't write or rewrite student work. It only gives feedback on what the student has already written, the same kind of feedback a teacher would give on a draft. Students still do all the thinking and writing.
What happens to student work?
Submissions are stored encrypted in our Sydney-based database. Text and the rubric are sent to the AI for analysis without student names or personal identifiers. The AI provider does not use API inputs to train their models. See our Privacy Policy for full details.
How reliable is the AI detection?
AI detection is an indicator, not proof. It checks four categories (language patterns, content red flags, style inconsistency, common AI phrases) and gives a Low, Medium, or High risk rating with supporting evidence. It should never be used as sole evidence of academic dishonesty. Teachers see this report; students don't.
What subjects does it cover?
30+ Australian subjects across all 7 faculties: HSIE, English, Mathematics, Science, PDHPE, Creative Arts, and TAS. Years 7 through 12, including Extension.
