I was hoping it would be something that tracks down citations too, because I have been looking for one of those for years. It actually searches and arranges the graph according to paper “similarity”, a metric based on how much the citations and references match. So it’s good for finding similar or related work but it’s not a citation tree.
Either way, a nicely designed tool and I’m glad to have discovered it.
If it means having things connected and having research in the name then yeah, but Roam is a tool for writing while this appears to be more of an infographic source to see how published papers are related
