Real handwritingwith AI recognition
In MathCracks, students don't select options or type: they write answers by hand. AI recognizes the handwriting and validates the answer. This is solving math for real.

Why handwriting?
Learning neuroscience research is clear: writing by hand activates neural networks that typing cannot reach.
Motor memory
Writing activates the motor cortex and creates stronger neural connections than typing. Students remember better what they write by hand.
Visuospatial coordination
Organizing an operation in space (aligning digits, writing fractions) develops spatial skills fundamental to mathematics.
Cognitive retention
Studies show that handwriting produces 25% more retention than selecting options or typing.
Real problem-solving process
In a real exam, students write. MathCracks trains the same skill. It's not guessing among options: it's thinking and writing the answer.
How the technology works
Four layers of technology work together to turn handwriting into validated mathematical answers.
Smart canvas
A digital canvas where students write with Apple Pencil, stylus, or finger. Supports strokes of any thickness and direction.
AI OCR recognition
Handwriting is sent to a specialized math OCR engine (Mathpix) that converts strokes into text and mathematical expressions.
Multilayer validation
The recognized answer is validated with multiple strategies: exact, numeric, symbolic (SymPy), Spanish text, and mathematical equivalences.
Eraser tool
Students can erase individual strokes to correct mistakes without clearing everything. Just like in a real notebook.
Compatible with all devices
Handwriting works on any touch device. The best experience is with a stylus, but finger also works.
iPad + Apple Pencil
The best experience. Millimeter precision, low latency, pressure sensitivity.
Android + Stylus
Full experience on Android tablets with compatible stylus.
Phone with finger
Also works on iPhone and Android without stylus, using finger. Ideal for quick practice.
Handwriting vs. multiple choice
Writing answers by hand activates deeper cognitive processes than selecting from options.
