LaTeX-OCR VS KaTeX

I didn't know that such tools exists (completly new to LaTex). Thanks to your suggestion I looked for an open source althernative (to avoid anoyances of freemium) and I found pix2tex That works really like a charm.

I have recently discovered a few very helpful github packages which help me make notes while listening to lectures. These would be 1. pix2tex (allows you to scan an equation and convert it to latex) 2. pix2text (allows you to scan an equation with words in it and converts it to latex and text) 3. Tesseract (not really a physics related package, but it does allow me to copy notes from transcripts easily) 4. Mathpix an app that performs all the above mentioned operations better than the packages above, but one which ain't free.

This is also a great aid to learing LaTex. I wonder if anyone has ever tried to make an OCR system that generates the appropriate LaTex from an picture of an equation?

Turns out the answer is yes:

LaTeX-OCR

I want to resolve this KaTeX issue, so in order to test my ideas, is there some LaTeX test file with just a lot of equations, preferably inline (since this issue is related to inline math) but without fancy libraries or stuff not included in KaTeX?

> Could you elaborate on why you switched away from it?

I started using KaTeX sometime after 2015 because it promised to be fast (the fastest! [1]). I had to change the representation of a bunch of expressions because KaTeX didn't support some environments, whilst MathJax did. It was a trade-off I was willing to accept at the time.

Many years later, I started writing a personal static-site generator. I wanted comparatively lightweight pages, so rendering server-side was an option. I re-evaluated MathJax vs KaTeX again and this time I leaned towards MathJax, as speed was no longer an issue for me. It looks like KaTeX has broader support now [2].

Another alternative: Create a WebView by using UIViewRepresentable and Webkit together with MathJax or Katex where Katex is the better option. Here is a link to katex: https://katex.org/

This isn't a LaTeX question. It's a web dev question. Probably best directed at folks who make (or use) KaTeX.

KaTeX

If you want to make it from scratch, go with https://www.slatejs.org/examples/richtext, then use something like https://katex.org/ for rendering the LaTeX, and maybe Mathjs.org for plotting.

The speed of KaTeX is great, but the lack of support for diagrams (a la tikz-cd) is what makes KaTeX unsuitable for general adoption by mathematicians (e.g., mathoverflow.net and all online mathematical wiki I know use MathJax). KaTeX has some rudimentary support for diagrams though the {CD} environment, but something more fully fledged akin to tizk-cd or xymatrix is needed. There's been some discussion on their github (https://github.com/KaTeX/KaTeX/issues/219), but I wouldn't hold my breath.

Haven't personally used it, but have heard of KaTeX
