[BlindMath] Screen reader extension for viewing math content in LaTeX and AsciiMath notations as MathML

Mon Sep 14 20:49:06 UTC 2020

Hi Akashdeep,
nvMathViewer provides the ability to perform the fastest possible conversion of any LaTeX or AsciiMath to MathML.
You just select the text and immediately view it as MathML.
This can be done in absolutely any place with one click. For example, in E-mail, on a web page, in a text file, and etc. No internet connection required.
To do this with standart MathJax, you would have to create a web page, include MathJax library to it, insert the formula into source code of this page and then open the page in your browser. And you will need to do all this every time for each next formula.
nvMathViewer does all this for you in one click and more efficient way through direct interaction with the MathJax engine.
Best regards, Nikita.

Hey Nikita,

I didn't get the utility of the add-on. Can you please more elaborate
on the utility of the add-on? How it is different from the MathJax?
