About Semantic Scholar
Semantic Scholar is a free, AI-powered research tool from the Allen Institute for AI that lets researchers, students, and academics search and understand over 237 million papers across all fields of science. It layers machine-learning features like semantic search and the Semantic Reader (an augmented in-browser reading experience) on top of a massive open corpus, and offers a public API so developers can build their own scholarly apps. Unlike subscription bibliometric databases, it is fully free and strongest in computer science, AI, and biomedicine.
