[P] citracer: a small CLI tool to trace where a concept comes from in a citation graph

Hi all, I made a small tool that I've been using for my own literature reviews and figured I'd share in case it's useful to anyone else. It takes a research PDF and a keyword, parses the bibliography with GROBID, finds the references that are cited near each occurrence of the keyword in the text, downloads those papers when they're on arXi or OpenReview, and recursively walks the resulting graph. The output is an interactive HTML visualization.
