My colleagues and I built a research prototype that integrates social media conversations about a paper into the paper reading experience. It retrieves relevant social media discussions about a paper and presents them alongside it, with double-sided synchronization so you can see which parts of the paper a discussion relates to and which discussions exist for any given section. The research paper on this work is published at UIST 2025 (
