Highlighting Image Text
We are going to be using an OCR (Optical Character Recognition) engine called Tesseract for the image-to-text recognition part. It is free software, released under the Apache License. Install the engine for your desired OS from their official website. I'm using Windows for this. Add the installation path to your environment variables.

Marker: Convert PDF to Markdown quickly with high accuracy
Last update was pretty recent, and the git mentions tesseract 5 as a dep. so it's likely moved on a bit from when you last tried it:
https://github.com/tesseract-ocr/tesseract/releases
I suppose it depends on your use-case. For personal tasks like this it should be more than sufficient, and won't need user details/cc or whatever to use it.

So You Decided to Extract Recipe Text From Scans of Your Grandpa's Old Cookbook Using Pytesseract (+ My Grandma's Fig Cake Recipe) (+ Hidden Recipes To Be Found)
Install Google Tesseract OCR (additional info how to install the engine on Linux, Mac OSX and Windows). You must be able to invoke the tesseract command as tesseract. If this isn’t the case, for example because tesseract isn’t in your PATH, you will have to change the “tesseract_cmd” variable pytesseract.pytesseract.tesseract_cmd. Under Debian/Ubuntu you can use the package tesseract-ocr. For Mac OS users. please install homebrew package tesseract.

Notes on Emacs Org Mode
Sorry, but _what exactly_ «it seems to do» from your point of view?
My «second brain» now is almost 300Mb of text, pictures, sound files, PDF and other stuff. As I already mentioned, it contains tables, mathematical formulae, sheet music, cross-references, code samples, UML diagrams and graphs in Graphviz format. It is versioned, indexed by local search engine, analyzed by AI assistant and shared between many computers and mobile devices. And (last but not least) it works: it allows me to solve my tasks way more faster than with the assistant of external, non-personalized tools (like ChatGPT, StackExchange or Google).
I know no tools for all this tasks except org-mode. Well, maybe Evernote in the 2010-s was something similar — but with less features, with more bugs and with worse interface.
Personal note-taking _is_ a complex task per se (well, at least for someone like typical HN visitor). I've seen many note-taking tools, that were ridiculously featureless, stupid and inconvenient because they were _not_ complex enough.
> Sure if one wants to do emacs-gardening it is fine.
1)You can use org-mode outside Emacs. See for example Logseq (https://logseq.com/), organice (https://organice.200ok.ch/) or EasyOrg.
2)Org-mode works in Emacs out of the box, you don't need any «emacs-gardening» to use org-mode.
3)The term «Emacs-gardening» itself sound a bit like hate-speech for me. The complexity of Emacs customization is overrated, mostly due to opinions of people who never used Emacs or used it in the previous millennium.

I'm a science student and amateur web dev. Is this the right tool?
While Emacs and Org mode can certainly be used for this (and, when they can't, you can always inject little python/js scripts in your emacs config to take care of specific things), I'd also recommend you take a look at Logseq.

Ask HN: What are some unpopular technologies you wish people knew more about?
My work notes (and email) has shifted into emacs but I'm still editing zimwiki formatted files w/ the many years of notes accumulated in it Though I've lost it moving to emacs, the Zim GUI has a nice backlink sidebar that's amazing for rediscovery. Zim also facilitates hierarchy (file and folder) renames which helps take the pressure off creating new files. I didn't make good use of the map plugin, but it's occasionally useful to see the graph of connected pages.
I'm (possibly unreasonably) frustrated with using the browser for editing text. Page loads and latency are noticeably, editor customization is limited, and shortcuts aren't what I've muscle memory for -- accidental ctrl-w (vim:swap focus, emacs/readline delete word) is devastating.
Zim and/or emacs is super speedy. Especially with local files. I using syncthing to get keep computers and phone synced. But, if starting fresh, I might look at things that using markdown or org-mode formatting instead. logseq (https://logseq.com/) looks pretty interesting there.
Sorry! Long answer.
