I'm curious who the audience is for this. If it's people who actually care about maths, then this doesn't have any real value, because they already know LaTeX and will most likely appreciate the higher precision that offers (I personally fall in that category). If it's people who normally don't really need to write mathematics, then for the few times they need to, LaTeX might still make more sense due to convenient quickly-googled online LaTeX creators like https://www.codecogs.com/latex/eqneditor.php

If there's a demographic between those two groups, then I might simply have a blind spot, but... whose problem does this solve, and what is that problem? Because just saying "LaTeX is too much effort", the immediate counter-question is "for whom, exactly?" because it won't be people who already use LaTeX, or need reliable maths typesetting on a daily basis, and it probably isn't for people who need to use maths maybe a handful of times a year. So who's left, and what problem do they have where asciimath makes life easier?
