Is there a program out there that can do this?
For example, I found a site which has the entire game script for Tokimeki Memorial: https://www8.big.or.jp/~gaterar/tkm/srf/srfind.html
And I'm looking for a program which can intake a raw text file of the entire script, parse it for individual words/kanji, grab definitions for them from Jisho or some other dictionary, then output the entire thing as a usable Anki deck. So that the end result is that I have a deck which contains all the vocab you would need to play through a game/read a book.
