What it does

Written by AI from the README

Runs MinerU on selected PDFs and stores the result as a Markdown attachment, with images and JSON output kept beside it. The source PDF is never changed.

Gets structured Markdown out of PDFs inside Zotero. Needs a separately installed local runtime. The current release targets Linux, Zotero 10 and Python 3.13, with CPU or NVIDIA profiles.

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
