Connected Papers builds a similarity graph from co-citation. scid.ai shows two graphs: direct citation links of one paper (what it cites and who cites it) and a topic graph over search results with clusters, years and organisations.
Yes. The citation graph is available on the free plan; usage is limited by the credits granted at sign-up.
Papers from the graph go to favorites and source groups, which export to BibTeX, RIS, EndNote and CSV.
