A web app for annotating research papers and exploring them with an AI assistant to aid understanding.
Open Paper is a web application for reading and annotating research papers. It is aimed at researchers, students and anyone who works through academic literature and wants a structured way to mark up papers and keep them organized. The product combines a personal library and projects with annotation tools and an Ask feature that helps users dig into paper content. A Discover section supports finding new papers. Access requires signing in, and the site presents the tool as a hosted service rather than a downloadable library.
