Inciteful, launched around 2020 and now also reachable through the related incitefulmed.com domain, builds a citation network around a starting paper the way Connected Papers does, but adds a second, more specific tool: Literature Connector, where a user enters two particular papers and sees the chain of citations linking them, useful for interdisciplinary researchers trying to bridge two fields that rarely cite each other directly.
That paper-to-paper connector is a genuinely different question than general graph exploration answers: not only what's related to this one paper, but specifically how do these two particular papers relate, a question that matters when bridging domains rather than deepening within one.
Inciteful remains free to use. For a researcher working across two different fields who needs to understand the specific citation path connecting them, not only a general map of one field's literature, Inciteful's Literature Connector addresses that narrower, genuinely useful question directly.
