Three-Dimensional Assessment Framework

See exactly which Bloom stage each student is stuck on.

Understanding
Bloom · Remember + Understand

Tracks whether students can explain the concept in their own words — not just produce a keyword.

Adaptability
Bloom · Apply + Analyse

Tracks transfer to unfamiliar problems. Catches pattern-matchers who memorise without understanding.

Flexibility
Bloom · Evaluate + Create

Tracks reasoning about edge cases and cross-topic connections — the hardest, most exam-relevant dimension.

What you get

Built around the three-dimensional framework — every feature feeds back into the per-student profile your class dashboards roll up.

IB-examiner co-design
Curriculum, markschemes, and grading rules built with an active IB Math examiner — not scraped from a textbook.
Pre-built syllabus
IB Math SL ships with 5 chapters, 24 topics, 86 examiner-validated notes, 142 past-paper questions, 64 flashcards.
Three-dimensional insight
Per-student dashboards on Understanding, Adaptability, Flexibility — see exactly which Bloom stage each student is stuck at.
Class-scoped scoring
Tune mastery thresholds, base gains, and gate values for THIS class — leaves the platform default and your other classes untouched.
Editable workflows + prompts
Visual workflow editor for lesson, topic, and revision flows. Tune the tutor's persona, feedback tone, and grading rules per class.
Markscheme-aligned grading
Real IB markschemes parsed into method/answer/reasoning marks. The grader matches the structure an IB examiner would expect.
Class analytics
Who's struggling, where, and on which Bloom level. Surface gaps the whole class hits together so you can re-teach in person.
Multiple AI models
Gemini 2.5 Flash, 2.5 Pro, 3 Flash — students pick per task. You set the default and cost ceiling per class.
Photo + voice answers
Students snap their handwriting; the model transcribes to LaTeX. Voice plays each tutor reply for read-aloud students.

IB Math is live. HKDSE and Australian are next.

Phase 1 is shipping today. AA SL/HL and AI SL/HL are fully covered with examiner-validated content. Hong Kong DSE templates already exist in the platform; Australian Curriculum (VCE, HSC, QCE, WACE) follows in parallel via the Melbourne Accelerator Program track.

When your subject lands, your class workflows port cleanly — the three-dimensional framework, scoring, and class-scoped settings are curriculum-agnostic.

Pricing

Cancel anytime · pay monthly

Token limits are per-educator. Students added to your class use your monthly allowance — if a student burns through their share they can buy extra credits or upgrade their personal plan to keep going.

Quick answers

Can I keep using my student account?
Yes — same email, same login. You're a student AND an educator at the same time. Use the tutor like a student to test prompts, then switch into the teacher portal.
What happens when my class runs out of tokens?
Students see a "monthly limit reached" prompt. They can buy a one-off credit (small fixed price) to keep going, or upgrade their personal plan. You as the educator can also lift the cap from the class settings.
Do students need to pay?
No — being added to your class gives them subscription benefits inherited from your plan. They only pay if they want to use the platform beyond your class's monthly allowance.
Is creating a class the only thing that costs?
Yes. Browsing, editing prompts globally, and reading the question bank are all free. Class creation is what triggers the subscription, because that's where the platform actually serves students at scale.
