LaTeX-OCR

What it does

Converts an image of a mathematical formula into the LaTeX that produces it, which removes the single most tedious step in writing anything with equations — retyping them. There is a GUI for snipping straight from the screen, and a hosted demo if you want to judge the accuracy before installing anything. Complex or handwritten formulas still come back wrong often enough that you should render and check every result. MIT.
