I am working for a company that had a very old data base and still does a lot with paper. I started working on digitizing and organizing everything and I found it would be easiest to scan in large batches but naming would take forever. I decided to build a pretty basic python script using OCR to pull the data from the PDFs and use it for renaming. Once it worked well, I fell down the rabbit hole of making it a web app and setting it up to be easy to setup (even for the very non technical).

You had a list of regions, and extracted text for each region and then created a new file name on the basis of region text and renamed the file.
