That doesn't really answer my question. Like, I have a website, and I have many references; I also use LLM embeddings for nearest-neighbors recommendations of references to each other.

What might this... do... for me? Don't dump a bunch of JS which is how I would 'do' whatever it does. What does it do? Like, can I dump the URL 'https://pmc.ncbi.nlm.nih.gov/articles/PMC4543385/' into it and get out nice usable clean text of the abstract, say? What about a complicated PDF like https://gwern.net/doc/psychiatry/anxiety/2025-he.pdf (these are the last two references I added)? What do I get? Do I have to install the whole darn thing just to see what it does?
