Very impressive! The only issue I've run into is it having trouble discerning lower-case and upper-case letters. Training with my own writing style should be able to correct this however.

Is there a plan to offer this as a non-web-browser service? I would love to be able to write math out on paper, or a resistive screen tablet, and then import it into a LaTeX document.

I am faster writing equations by hand than typing LaTeX (and definitely faster compared to using a WYSIWYG equation program).

Edit: By the way, this is the perfect example of a problem I've always wished a start-up would come along and solve for me.
