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.

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

Tried "what is (x-2-1)/(x-1)?" and got absolute gibberish in return

Do you have a screenshot of what you got? Or can you describe it? I just tried it and it gave the correct answer.

Now that I'm looking more carefully at the answer, it is probably correct but just formatted badly with overlapping text - https://imgur.com/a/F7awsTY

Ah — I see! Thanks for taking a screenshot.

Will work on making the spacing better on desktop!

agreed. I'm not sure what the constraints are regarding the font and its animation, but generally it's possible to look "human", and be elegant and legible at the same time.

It looks almost like my handwriting :). It's interesting that each time it shows a different variant. Anyway, when I press " get the derivative of f(x)=x^2 " I get 2-1 f'(x) = 2 x but the 1 is too big. (Do you need a screenshot?)

Using a variety of hand-written inputs, so font variation would be present. If you could give a screenshot, that’d be helpful!

I run it again and got this: https://imgur.com/a/3t1Xvtg

I added labels to show the problem (but they are too small) and I used Paint to create a fake version where the 1 has the size I'd like.
