If I get the AI to mark students' papers through Mindjoy, I'm still going to check if it got it right, but it's going to take me a fraction of the time than if I had to sit there and mark.
Why mark with Mindjoy?
A generic AI gives generic comments. Here's what makes Mindjoy's marking different — and safe to put in front of students.
Marks to your rubric
From your content, Mindjoy drafts a full mark scheme — credit for each step and all — which you can edit or override. It marks the actual working and reasoning, not just keyword or text matches.
Solve 3(x + 2) = 5x - 4 · 3 marks
Handwritten submissions
Students snap a photo of their handwritten working — diagrams, equations and messy margins included — and Mindjoy marks it just like a typed answer.
Formative & summative
Built for both. Formative gets rich settings — multiple retries, hints and instant feedback to build mastery. Summative locks down with timed, test-conditions assessments.
- Multiple retries
- Hints & support
- Instant feedback
- Timed
- Test conditions
- One attempt
Class insights
Just ask Mindjoy in a chat how the class did — across one assignment, a whole test, or the term. Spot common misconceptions and who needs support, in seconds.
No made-up feedback
Every comment quotes what the student actually wrote — no invented praise, no hallucinated mistakes.
Because the Sun moves around the Earth.
Feedback quotes the exact phrase — grounded in what they wrote, nothing invented.
Override anything
Feedback is auto-generated and accurate enough to send as-is — you rarely need to touch it. But you can always review and override any comment before it reaches a student.
Clear explanation — to reach full marks, add that the Earth spins on its own axis.
A built-in AI tutor
Stuck on the feedback? Students ask follow-up questions to a teacher-supervised Mindjoy tutor, right there.
Marked in seconds, not days
Feedback lands within ~10 seconds of a student submitting — while the work is still fresh in their mind.
Feedback that grows students
Specific, encouraging next steps — not just a score. The kind of comment that actually helps a student improve.
Great use of evidence. Next step: add one example to your second point and you'll reach the top band.

Every student deserves real feedback
The feedback that actually helps students improve takes time no teacher ever has enough of — so most answers come back with just a mark. See the same answer marked the usual way vs with Mindjoy.
Why do we have day and night on Earth?
Because the Sun moves around the Earth.
“Not quite. See me.”
- A mark, not guidance
- Arrives days later
- The misconception goes uncorrected
Why do we have day and night on Earth?
Because the Sun moves around the Earth.
What you did well
You've recognised that day and night involve both the Sun and the Earth — that's the right place to start.
Where the gap is
The Sun doesn't move around us. That's a really common mix-up, so let's untangle it.
Your next step
Explain that the Earth spins on its own axis once every 24 hours — the side facing the Sun has day, the side turned away has night. Try rewriting your answer with that idea.
- Specific, rubric-anchored
- Delivered in real time
- A clear next step — reviewed & approved by you
