Could you build this?
Partial The notebook, plotting, and Python execution parts are vibe-codeable, but accurate offline handwritten math recognition and symbolic math on-device are hard machine learning problems.
What it would actually take: Combine PencilKit stroke capture with an on-device handwriting recognition model trained or fine-tuned for mathematical notation, then convert recognized expressions to LaTeX or a symbolic AST. Run Python offline via an embedded interpreter and a symbolic engine such as SymPy-equivalent code. The difficult parts are the math OCR model, with its training data and accuracy tuning, and the iOS embedding of the Python runtime. This requires ML engineers experienced with handwriting recognition and iOS performance work.
