A bit too sloppy and a bit too slow for my taste, but otherwise great!

Actively working on making the font more legible and adding a “speed slider”!

You should label the top end of the slider "TA"

Nice tool! I like the human like handwriting, but I'd prefer a more adult one. Writing the denominator first looks weird to me, same as writing the square root symbol after what's under it.

Writing the radical sign last is a sign of sophistication of maturity.

Agreed the ordering is a bit weird. Working on figuring out a way to adjust that. Thanks for the feedback!

Also I would expect that the letters are consistent. Not necessarily legible, but always quite the same.

Fun project, although it does seem to struggle with writing the longer it goes https://imgur.com/TntAViO

Looks like my 5 year old's handwriting. Sometimes I actually have no idea what it was writing. Plus the text was overlapping at times

It solved `(x^2-1)/(x-1)` to `x+1` but it is not equal. It should be specified that `x` must not be equal 1 in this case.

What are you using to make handwritten text? Is it a model?
