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.
