Capcul - Turn screen captures into instant calculations with OCR + AI

Built Capcul to solve one specific annoyance: manually typing numbers from PDFs/images into calculators. The idea is simple - capture any numbers from your screen and they instantly become clickable calculator buttons. No more transcription errors or tedious retyping! The technical challenge was making OCR work reliably across different fonts, image qualities, and screen resolutions. Plus adding an AI layer that can help with complex calculations. Perfect for students, researchers, or anyone who regularly works with data from documents. What do you think? Does this workflow problem resonate with others?
