Citation gaps

Finds papers cited by two or more papers already on your map that aren't in the map yet.

The graph-native gap-check

If two or more papers already on your map both cite the same third paper, and that third paper isn't on the map itself, it's surfaced as a gap - the kind of paper a careful literature review shouldn't miss, found automatically from the structure of the citation graph rather than by re-reading every reference list by hand.
