Thanks! If you right click on any LaTeX you can access the raw TeX code. Admittedly this is just the default MathJax behaviour though haha. If people wanted it then I could probably make it easier to get the TeX in fewer clicks.

I thought that it might be useful to use this application to generate TeX, so one feature I'm working on is to fine tune the output format (e.g. choosing the multiplication symbol, instead of \cdot, maybe \times or \,).

Thanks for trying it!
