My DSE Maths score went from Level 4 to Level 5**. Seeing the geometry instead of just imagining it was the difference between guessing and actually solving the paper.

DSE Candidate

I could never visualise locus and 3D trigonometry questions from just the textbook diagrams. Practising with SketchMath's dynamic graphs got me a 5* in DSE Extended Module 2, and an offer for Actuarial Science at HKU.

Functions and graph transformations never made sense until I could actually drag the graph and watch it change. My DSE Maths score jumped to Level 5*, and I'm now studying Quantitative Finance at CUHK.

SketchMath brings DSE Mathematics to life for students who need to see a concept before they can solve it. It is especially useful for explaining coordinate geometry and graphing clearly enough for the exam.

It gave our students the confidence to tackle Paper 2 and the Extended Modules, and several went on to study Engineering and Actuarial Science at HKU and CUHK.

Visual Learning

Math gets hard when you cannot see it.

Students get stuck when math stays invisible. SketchMath turns abstract questions into visuals you can inspect and learn from.

Why SketchMath

Your math tutor that shows, not tells.

Built for visual math.
Geometry, graphs, loci, and 3D questions where understanding depends on seeing the structure, not just reading text.
Supports teachers, not replaces them.
Use SketchMath to make hard diagrams visible faster in class, while students stay engaged in each step of the reasoning.
Optimized for real exams.
Tuned for HKDSE and related curricula, then extended to IB, A-levels, and foundation university math.
Grounded in real classrooms.
Built by HKU students with academic supervision, and aligned with modern math teaching practice.

Frequently asked questions

Because students learn more when they attempt the next step themselves. SketchMath gives guidance and feedback during the process instead of immediately revealing the whole solution. Recommended by GeoGebra CTO.

We collaborate with leading education and innovation partners to build math learning experiences that are both effective and genuinely engaging — so every student can discover the joy of mathematics.

Most general AI tools are built to answer quickly. SketchMath is built to make math visible — especially for geometry, graphs, loci, and 3D questions where understanding depends on seeing the structure, not just reading a text solution.

No. SketchMath is designed to support learning, not shortcut it. Students are guided through the reasoning with visuals and feedback along the way.

Yes. SketchMath is optimized for advanced geometry, trigonometry, and calculus across major curricula including HKDSE (Core & M1/M2), IB Math (AA & AI), GCE A-Levels, and IGCSE. It also supports preparation for AP Calculus (AB/BC), SAT/ACT Math, JEE, and foundation-year university math by turning abstract formulas into interactive 3D models.

SketchMath bridges 2D textbooks and 3D intuition. You can generate, rotate, and inspect high-fidelity 3D visualizations to understand 3D trigonometry, projection angles, and the angle between a line and a plane. We are also building tools to manipulate solids, intersect planes, and explore cross-sections for deeper spatial understanding.

Yes. SketchMath is free for students and educators. You can solve geometry problems, visualize 3D constructions, and get AI-guided steps in your browser at no cost. Teachers can also create GeoGebra-based visuals for lessons for free.
