Understand this story
Ai2 and the University of Pennsylvania collaborated to develop the LitPivot system, which aims to help researchers dynamically adjust their research direction during the literature search process. The system retrieves papers through Asta Paper Finder, organizes the literature according to the parts edited in the proposal, and provides critiques supported by excerpts from the original texts, as well as revision suggestions that can be accepted, edited, or rejected. In an experiment involving 17 researchers, domain experts found that research ideas formed using LitPivot were more grounded in the literature than ideas formed using a text editor plus AI chat tools; participants also self-reported more pronounced improvements in the novelty and usefulness of their ideas. The system will be presented at UIST 2026.

LitPivot: Dynamically Contextualizing Research Ideas in the Literature Landscape
Ai2, in collaboration with the University of Pennsylvania, developed LitPivot, a system that helps researchers adjust their research direction during literature search. It retrieves papers via Asta Paper Finder, organizes the literature according to the edited portions of a proposal, and provides critiques supported by excerpts from the original text along with suggestions to accept, edit, or reject revisions. In an experiment involving 17 researchers, domain experts judged that research ideas formed with LitPivot were better grounded in the literature than ideas formed with a text editor plus AI chat tools, and participants self-reported more pronounced improvements in the novelty and usefulness of their ideas. The system will be presented at UIST 2026.
