MathJax VS mathquill

Developer tools point to MathJax https://www.mathjax.org/. If you disable javascript you can see some LaTex.

It is something we could add, but it is not planned in the near future. We also have requests for adding math notation (like https://www.mathjax.org/), and that could be a more general solution.

I don't know what Obsidian is, but if it's requiring old TeX math mode toggles (the double dollar sign), then it might not actually be using LaTeX underneath. Many tools that provide LaTeX-style syntax for equations are actually using something like MathJaX, BlahTex, or some custom system by which to translate LaTeX-like syntax into their own equation rendering. This often means you only get a pre-defined subset of what's possible with LaTeX (and the results are never quite faithful to how LaTeX would typeset them).

This will depend heavily on where you're asking the question, e.g. stackexchange has built in mathjax to render it. I'm going to assume you're intending to ask here (because that would make sense), in which case check out the bottom of the sidebar.

From the screenshot, Obsidian looks like a typical Markdown editor that supports some LaTeX math syntax, probably rendered with something like Mathjax. On the other hand, Xournalapp seems to actually use LaTeX, even allowing you to use LaTeX packages like graphicx, tikz, etc.

In MathQuill(http://mathquill.com/), the field in which you type is "faked" with js. Even the cursor is just a `span`.

What are the benefits of going the faked route as opposed to building on contenteditable?

Typing equations for maths is very tedious in Anki. Well, until now, I've been using mathquill to type equations in a browser, copy it to anki and use mathjax to render it. I was wondering if anyone could simplify the process integrating it to anki itself.

Desmos has open source library called MathQuill, which converts typed chars to mathematical representation similar to Mathematica. Sure there is some "programming statements" like (La)TeX like syntax there, but so does Mathematica too.

I also found this math input library: http://mathquill.com/ , and https://mathjs.org/ seems to contain code for solving math problems.

So I found a much easier way to use LaTeX. There is this lovely auto-editor for LaTeX here: http://mathquill.com/

You might want to look for a component that can render MathML. On the web some browsers can do it or there's MathJax. There's also MathQuill to enter formulas in the browser.
