When i was still playing diablo 4 i made a swiftui app where i would take a picture of two items up for comparison and would use gpt-4 to determine what was the better choice. I found that apple's OCR through Vision kit or whatever its called is really good.

I would front-load the prompt with a dictionary of stats i cared most about in a 1-5 ranking system for that character, this setup via through another screen's ui.
