SnapXam

SnapXam offers symbolic, text and photo entry with examples distinguishing operations such as simplification, limits and differentiation. Its developer documentation separates image recognition, solving, simplification and factoring: recognition returns LaTeX and infix notation, while mathematical operations return an answer in those forms where available. Simplification has an include_steps option for the working. A published factoring example maps x²−5x+6 to (x−2)(x−3). The API requires a bearer key and supports LaTeX, infix or base64 image input; this is separate from the website's Premium route for students/teachers. Check recognized notation before using the result, and retain domain restrictions when a simplification cancels an expression's denominator.
