Pair this with a snipping tool and all sorts of people in banking would use it for a few hours a day, especially if it could paste to Excel or at least fill the clipboard in a way pastable to Excel.
I used to work for a bank on their innovation team and pitched basically this, but as an intern I had neither the skill nor time to do it. But it was certainly something a bunch of people internally wanted.
Do you happen to know how to paste regular UTF-8 text into Excel/Google sheets as multiple cells? If I copy two cells in Sheets, I get a tab character (\t) between the cells. But if I try to paste "hello \t world" into Sheets then it's just dumped into one cell.
At least my bank was comfortable with cloud everything and people using APIs from approved partners. If you can write the report in Google Docs, as long as they were the ones plugging in their API key for the OCR, I imagine it would be fine.
