org-noter VS youtube-sub-extractor.el

I regularly paste text from other sources (e.g. a bit of Wikipedia text for a stub note, or highlighted text from a PDF via org-noter) into my notes and what I am looking for is a way to find/indicate existing org-roam entries in those pieces of text.

So right now I am having to go through tons of reading material. I'm taking an abundance of notes, etc. I'm trying to prep for an exam. I need to read multiple books, and I just started with the first one. I opened PDF-tools and then, using Org-noter I started taking notes. Each note is like an annotation in the book, tied to its specific location. Next time when I go through my notes, I can jump to the specific page in the book. And vice-versa - while re-reading through the book, I can see all related notes, right there in the adjacent window.

First, make sure that you are using this repo, instead of the other one which is unmantained for a couple years. It includes a lot of fixes and new features that with luck might fix your issues.

Thank you for your detailed answer - I am not OP but I just wanted to point out (in case you were unaware) that the great org-noter has recently found a new maintainer and the repo has moved here: https://github.com/org-noter/org-noter

An alternative is to open PDFs, from Zotero or from anywhere else, with Emacs' pdf-tools (https://github.com/vedang/pdf-tools). If you annotate the pdf, those annotations are part of the pdf. And you can also use org-noter (https://github.com/weirdNox/org-noter) and org-noter-pdftools (https://github.com/fuxialexander/org-pdftools; but see https://github.com/fuxialexander/org-pdftools/issues/93#issuecomment-1493314118 if you use the new org-noter from https://github.com/org-noter/org-noter).

The maintained repo is at https://github.com/org-noter/org-noter and the branch you want is https://github.com/org-noter/org-noter/tree/bugfix/nov-mode.

Possibly: Org-noter and/or PDF Tools.

I am also finding many great videos on YouTube. I found that I learn the material better if I read through the transcripts. I usually pull the subtitles and use them to make more notes.

I like eww because it allows me to focus on the text. I love text; text is awesome, it lets me slash through the forest of information without having my mind wander around, overstimulating my brain neurons with fonts, colors, background images, icons, side banners, ads, etc. If you've never read Graydon's "Always bet on text" post, definitely give it a gander. I agree with it almost entirely. Lately, I even stopped watching YouTube videos to learn anything, at least, not without speeding them up to 1.5x. But first, I would extract subtitles and quickly read through them, and then proceed to the watching. That lets me learn things and retain information much better. Yes, text is not perfect and interactive, visual data has incredible value and very often text just cannot replace it. But my initial instinct is to scout the text first, and then, if needed get to rest.
