About This Launch
Derive is a handwriting notebook for maths, science and engineering students. You write on an infinite canvas with your pen and it reads the working as actual maths. Each line gets checked against the one above, so if you drop a negative on line three you find out on line three. If you get stuck, there is a tutor panel next to the page that helps with the step you are on. It also turns your notes into practice questions and exports your handwriting as LaTeX. On iPad, iPhone, Mac, Windows and the web, with a 7-day free trial.
Why I Built This
I kept losing marks to small slips early in long problems that only showed up when the final answer was wrong. I wanted a notebook that points at the line where it went wrong while I am still writing, so I built one.
