I don’t know of any solution that would allow to scan entire pages, but here is a local tool to get LaTeX math from images via OCR https://github.com/lukas-blecher/LaTeX-OCR

Handwriting has been proven to enhance learning in humans, so you are doing great by keeping the habit!

I don’t have much to recommend, but so far this little tool was very useful for me and my math studies: https://github.com/lukas-blecher/LaTeX-OCR

I am not a student, but I learn like a student all the time. I also enjoy handwriting (got an e-ink tablet for that) and knowledge management. I am often dreaming of a “perfect setup” where all I write gets pushed automatically through OCR into my knowledge vault (Obsidian, Logseq or whatever I/my peers happen to use). Even came up with a plan. I hope this new year will leave me enough energy to execute something useful.

Would you like to collaborate on that perhaps?
