About MarkMate

The Problem

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

The Solution

MarkMate gives students instant, rubric-aligned feedback on their drafts beforethey submit. The AI marks like a real teacher — checking argument structure, source usage, vocabulary, spelling (Australian English, of course), and whether they've actually answered the question. Students can revise and re-check until they're confident.

For teachers, MarkMate saves hours of marking time. Upload a task notification, share a link, and let students check their own work. Or upload student responses directly and get them marked with AI detection built in.

Built for Australian Schools

MarkMate isn't a generic grammar checker. It's built specifically for the Australian education context:

• 30+ Australian subjects across HSIE, English, Science, PDHPE, Creative Arts, and TAS
• Australian curriculum directive verbs — checks if students evaluate when the task says evaluate, not just describe
• Australian English — spelling and grammar checked against Australian standards
• Writing frameworks — PEEL, TEEL, STEEL, TEE suggested where appropriate
• Flexible grading formats — works with band descriptors, letter grades, marks out of a total, or any custom rubric scale
• Years 7-12 — adjusts expectations based on the stage of learning

Quality, Not Shortcuts

Every check uses Claude Sonnet — a premium AI model. We don't use cheaper models to cut costs. The quality of feedback is what makes MarkMate worth using, and we won't compromise on that. If the feedback isn't as good as what a teacher would give, we haven't done our job.
