How do you achieve the same things without AI here using that tool?

"How do you do it without AI" is a question I (sadly) expect to see more often.

Feel free to answer then, how do you do the same functions this does with gpt(3/4) without AI?

Edit -

This is an excellent use of it, a free text human input capable of doing things like extracting summaries. It does not seem to be used at all for the basic task of extracting content, but for post filtering.

I think “copy from a PDF” could be improved with AI. It’s been 30 years and I still get new lines in the middle of sentences when I try to copy from one.

That's a great use case, you might be able to do this if you've got a copy and paste on the command line with

In between. An alias like pdfwtf translating to "paste | llm command | copy"

i've long assumed that is a "feature" of PDF akin to DRM. Making copying text from a PDF makes sense from a publisher's standpoint.

Meh, it’s just the “how does it work?” question. How content extractors work is interesting and not obvious nor trivial.

And even when you see how readability parser works, AI handles most of the edge cases that content extractors fail on, so they are genuinely superseded by LLMs.
