Our Mission

About Ocean of Papers

We believe scientific knowledge belongs to everyone. Ocean of Papers makes 250 million research papers freely searchable — no paywall, no subscription, no account required.

Why We Built This

For most people — students, independent researchers, medical professionals, journalists, and curious minds — accessing scientific literature means hitting paywalls, navigating clunky university portals, or paying hundreds of dollars for a single PDF.

Ocean of Papers was built to change that. We aggregate the world's largest open-access scientific databases into one clean, fast interface. Search once, find papers across six major databases, access PDFs directly, visualize citation networks, and export your references — completely free.

The name reflects the idea that scientific knowledge is an ocean: vast, deep, and full of discoveries worth making. We give you a way to navigate it.
