OpenReview
What OpenReview is
OpenReview is a configurable web platform for peer review and scientific communication. It helps scholarly venues manage submissions and coordinate the work of authors, reviewers, and editors across multiple review stages. Organizers can set up review forms, permissions, and timing; after a paper is accepted, its forum can host reviews, comments, and continued discussion.
For reviewer assignment, OpenReview can match papers and reviewers using expertise, bids, and constraints, with reviewer balancing also available. Venues may enable real-time committee chat on paper forums, where messages are hidden from authors and the public by default. A REST API exposes records, groups, documents, invitations, assignments, conflicts, and workflow automation. Organizers request a venue using a support form, and the OpenReview team reviews and deploys it. The platform is free, with paper access and submissions available without fees. Its web interface is free software under the GNU Affero General Public License v3, and other components are also open source. OpenReview describes itself as a long-term nonprofit project created by a research lab at the University of Massachusetts Amherst.
