Citation Graph — Free ResearchRabbit Analog

Overview

A free, account-free, key-less alternative to ResearchRabbit and Connected Papers. Given a seed DOI (or several seeds), this skill walks the OpenAlex citation network outward in both directions and assembles a citation / co-citation graph of the local literature:

• Backward edges — the works each seed cites (its referenced_works).
• Forward edges — the works that cite each seed (its cited_by set).

It then ranks the discovered neighbourhood by co-citation strength — how many of the seed papers a candidate work connects to, via shared references, shared citers, and direct seed links — surfacing the papers most central to the topic, just like ResearchRabbit's "Similar Work" panels. The whole graph is exported as GraphML (open in Gephi, Cytoscape, yEd, or networkx) and JSON (for downstream code).
