Great idea!
I'm working on something similar, digitising my daughter's 213 pages of medical bills by building an app specifically for digitising printed medical bills. https://kingsley.sh/posts/2022/digitising-213-pages-of-medic...
Everyone kept saying "make sure to check your statements", but when the statements came, they're 9pt font, 50-70 line items per page. 1 page, yes, 10, maybe, 213 is impossible.
In the middle of working on it last week, I got a $3000 medical bill, for my daughter who passed away 1.5+ years ago, for part of her 7 month ICU stay 2+ years ago.
