Connected Papers
Visual graphs that map the literature around any academic paper.
Connected Papers builds an interactive similarity graph around a seed paper, clustering related work by how strongly papers share references and citations rather than direct links alone. Researchers use it to get up to speed on a field, find prior and derivative work a keyword search misses, and explore a visual map of a research area. The free tier allows a handful of graphs per month, with unlimited graphs on paid academic and business plans.
Worth knowing
Builds its graphs from co-citation and bibliographic coupling over the Semantic Scholar corpus, not direct citations.
