What it does

Written by AI from the README

Converts the PDFs of selected items to Markdown files in a folder using pymupdf4llm, with OCR for scans if Tesseract is installed. Scores each result and puts doubtful ones in a needs-review folder.

Prepares papers for note-taking apps or LLMs, locally with nothing uploaded. Tested on macOS only; needs uv or Python 3.

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.
