I turned a notebook full of handwritten math into a LaTeX paper — here's how

Here's a scenario I'll bet some of you recognize: you've been working through a problem by hand for weeks. Your notebook is full of half-finished derivations, scribbled integrals, matrices with question marks next to them. And now you need to turn that mess into a proper LaTeX document. I had exactly this situation last winter. Forty-odd pages of handwritten notes from a research project, and a paper deadline looming. I knew I couldn't retype everything — especially not the equations. There had to be a better way. The copy-paste treadmill The first tool I tried was Mathpix Snip. It's well-known in academic circles for a reason: the OCR accuracy on mathematical notation is genuinely impressive. You screenshot a handwritten equation, and you get clean LaTeX back within seconds. The problem wasn't the accuracy. The problem was the workflow. Every single equation involved: Take a screenshot or photo Switch to the OCR tool Wait for conversion Copy the LaTeX Switch back to my editor Paste an
