There's a tool I use called Petal https://www.petal.org/reference-manager. The free tier allows up to 1GB of PDFs, which I believe are processed by GROBID and chunked for LLM QA.

The feature I find most useful is the table automation which I use for literature review, since it lets me run the same QA prompts on a collection of documents all at once.

I was too but I posted anyway. I'd like it built into a legitimate plugin inside the zotero app.

That would be fantastic. At the moment the barrier to entry to use this kind of models is quite high. Something that could be used from the GUI would be great.
