Interesting! I’ll give it a try, I have a couple of large books to OCR (to be honest, the name in all caps with underscores is not really encouraging).

From your experience, how does the OCR engine work with multiple-columns documents?

The iOS app would likely not handle two-column text very well. I really made the iOS app on a lark for personal use, the whole thing took like 2 hours, and I'd never even made a Swift or iOS app before. It actually took longer to submit it to the App Store than it did to create it from scratch, because all the hard stuff in the app uses built-in iOS APIs for file loading, PDF reading, screenshot extraction, OCR, NLP for sentence splitting, and sharing the output.

I think the project I submitted here would do that better, particularly if you revised the first prompt to include an instruction about handling two column text (like "Attempt to determine if the extracted text actually came from two columns of original text; if so, reformat accordingly.")

The beauty of this kind of prompt engineering code is that you can literally change how the program works just by editing the text in the prompt templates!

Thanks, I’ll try to play with this. Thanks also for keeping us updated, your work is very interesting!
