Open Paper is a web product for annotating and understanding research papers. Its public pages position it as a place to sign in, access papers and projects, and work with annotations.
The pricing page shows that the product is organized around a research workflow: upload papers, annotate them, use chat credits and audio overviews for deeper review, and manage material in a knowledge base and projects. The site also lists a free Base plan, a paid Researcher plan for independent researchers and academics, and a Teams plan marked as coming soon.

Use cases
Close reading of a paper
A researcher uploads a paper, marks key passages, and returns to those annotations while reviewing the argument or methods.
Managing a research project
An independent researcher keeps several papers and notes together in a project so the material stays organized around one topic.
Exploring a paper in multiple formats
A reader uses chat credits and audio overviews to work through a paper in a different format when a quick summary or guided review is useful.
Organizing source material
A person building a small reading library uses the knowledge base to store related material alongside uploaded papers.
