Who it's for

Academic researchers, PhD students, and research teams who need to collect, organize, and cite scholarly papers while writing.

What you get

A cloud-based library for saving and organizing PDFs and references, with browser extensions and mobile apps for capturing papers from anywhere. It includes PDF annotation and highlighting, thousands of citation styles for inserting citations and generating bibliographies, and shared folders for collaborating on paper collections. Files sync via the user's own Google Drive.

How it works

Users sign in with a Google account and build their library through a Chrome extension, web app, or mobile app; a Google Docs add-on (and Word plugin) then inserts citations and formats bibliographies directly inside documents as they write.
