LitPivot: Ai2's System Helps Researchers Pivot Research Ideas Through Literature

Ai2 and University of Pennsylvania researchers built LitPivot, a system that organizes retrieved papers around the facet of a research proposal being edited and suggests literature-backed revisions. In a study with 17 researchers, domain experts rated ideas developed with LitPivot as better grounded in the literature than those built with a text editor and an AI chat tool. Participants also reported their revised ideas as more novel and useful, and LitPivot will be presented at UIST 2026.
