Leave the grading to AI,
and focus on teaching
Upload a whole class's papers and grade them on the spot, awarding step marks by your own marking scheme; class management, automatic class reports, and unlimited paper building and assignment free teachers from repetitive marking.

Start with a free AI marking-point diagnosis for one class
Send us one quiz; get back a class loss heatmap, per-student reports and parent-ready material. No sign-up, data deleted in 30 days.
We sell capability, not someone else's papers
The platform works on your institution's own content — compliant, in your control, and smarter about your students the more you use it.
Upload a whole class's handwritten answers and AI grades them step by step against「your own marking scheme」, saving hours of marking, with key questions open to human review.
Upload your institution's own questions and marking references, auto-structured and precisely tied to the syllabus's「smallest point」(strand→unit→objective). It grades and builds papers by syllabus point, with your data kept private.
Per-student weak-point reports plus a class-wide summary at a glance — teach with focus and back up every parent conversation.
Build papers by syllabus point or difficulty in one click, assign homework and timed mock exams, with student answers graded and fed back automatically.
One parent question auto-generates many verified variant questions (blind-solve + SymPy cross-check) — unique answers, no copyright risk, so volume is no longer a bottleneck.
SymPy deterministic checks plus LLM step-by-step grading make math marks defensible — institutions can rely on it and parents can trust it.
Three steps to hand grading to AI
Scan or photograph the whole class's papers and upload them together with your marking references.
Award marks step by step against your marking scheme, auto-pinpoint where marks are lost, with key questions open to review.
Turn class-wide and per-student weak points into a report, then assign targeted practice and mock exams in one click.
Not just fast grading — teaching backed by data
Two things no one else has nailed — grading by your own scheme, and pinning class analytics to a single syllabus point.
Leave the grading to AI — by your own marking scheme
Scan or photograph a whole class's handwritten papers, and AI awards marks step by step using your institution's「own rubric」— M and A marks broken down to each step, lost marks pinpointed automatically, key questions kept for a final human check. Save hours of marking each week so teachers can focus on teaching.
- Batch the whole class: dozens of papers graded in parallel, full-class scores in minutes
- Your scheme: marks awarded by your institution's own references, not a generic standard — consistent with your teachers
- Reviewable: one-click human final check on key questions — institutions can rely on it, parents can trust it
See where the class is weak, down to a single syllabus point
Per-student and class-wide summaries become reports automatically, with weak points pinned to the smallest three-level DSE syllabus point — not a vague「weak at algebra」but the exact「discriminant and roots」. Grade distribution and improvement trends at a glance; export to parents in one click, assign targeted practice by weak area in one click.
- Pinpoint precisely: class weak points mapped to the DSE syllabus so teaching stays focused
- Grade distribution + trends: 5**~≤3 spread and gains since last time at a glance
- Accountable to parents: one-click report export plus one-click practice by weak area, closing the loop
