Mathup: A Lightweight Alternative to MathJax for Writing MathML

Tensor Notation in Mathup

I created Mathup to solve the frustration of writing complex mathematical expressions in TeX. Unlike the heavy MathJax library, this lightweight tool converts simple, readable AsciiMath-inspired syntax directly into structured MathML. It is designed for speed and simplicity, allowing you to author math quickly without the overhead of verbose commands or rendering engines.

"MathJax is definitely overkill if all you want to do is translate simple expressions into structured form."
