Handwritten OCR is still pretty bad cuz people write super differently. Printed text follows clear patterns, but handwriting can be messy, tilted, or rushed. I noticed most OCR tools completely fail on notes from lectures. One thing that actually helped me tho was Clever Humanizer Grammar Checker. After OCR messes up words or grammar, I paste the text there and it fixes everything really fast. Makes the final text way more readable and natural tbh.
