Are there any plans for an interactive equation editor supported by KaTeX? I think this is something the web is missing. I've been following the MathJax dev google group, and it seems like there aren't any solid plans for them to implement this feature.

Some examples:

My attempt: http://camdenre.github.io/src/app/html/EquationEditor

Mathway: https://www.mathway.com/

Mathjq: http://www.mathjq.com/math-editor/

It would be nice to have something officially supported by a large project. I think that there is a lot of potential on the web for interactive math lessons with symbolic input using a CAS (not multiple choice).

There aren't any plans at the moment. We've struggled with this problem before, and wrote something similar with https://github.com/khan/KAS/ but we've never worked at doing something inline. We use MathQuill in a couple places, which does the input decently (writing works, but typing something like x^2_2 gives you x^{2_2} not x^2_2), but the output doesn't look great. It's hard to do what the user wants, have clickable bits, and still have good looking output.

I agree that it's a very difficult problem. I think that it's a major missing piece for online math learning right now (actually interacting with math symbols in a non ASCII/textbox way). Thanks for all of the hard work you guys do!

I recently made this little tool for writing latex macros: http://kasperpeulen.github.io/PressAndHold/ It works the same as the OSX press and hold accent picker. I have also a unicode version which I think is much more appealing for young mathematicians: http://kasperpeulen.github.io/PressAndHold/Unicode/

All MIT licensed if you are interested in using it.

Desmos (supporting MathQuill) is leading the space here I think: https://www.desmos.com/calculator

Absolutely agree that if this was made and made open there would be a lot of opportunities in the math education space.
