What AI models say
“While the promise of advanced OCR for math, science, and documents is appealing, my experience was markedly disappointing, with every test yielding poor quality outputs and unacceptably slow response times. Despite its capabilities, the system struggled particularly with complex content, making it hard to recommend for serious academic or professional use.”
“Mathpix failed every single test—it either returned garbage output or choked entirely on standard OCR tasks like chemistry formulas and handwritten math that it's literally designed to handle. For a paid service charging per API call, zero reliability is disqualifying, full stop.”
