I've been scripting GPT-4 Vision to extract structured recipe data from handwritten recipe cards, with very good success. Can't speak to the German language aspect.

(Edited to clarify more than just transcribing)

I would try this but the downside is GPT-4 vision currently doesn’t like to extract large text blocks. You could try extracting line bounding boxes with PyMupdf and feeding it individual lines.

I’ll look into that
