Free AI research tool indexing 200M+ academic papers
Updated
Semantic Scholar is a free, AI-powered research tool for scientific literature, run by Ai2 (the Allen Institute for AI), a non-profit research institute founded in 2014 by Microsoft co-founder Paul Allen. It indexes over 200 million academic papers.
Papers come from publisher partnerships, data providers and web crawls. You search, read results ranked with AI, open papers in the Semantic Reader, and explore citations. Developers use the API to retrieve the Academic Graph, and researchers use the S2ORC corpus. The service is free.
Researchers, students and scientists use it to find and read literature, and developers and academics use the API and datasets for research projects.
Semantic Scholar is completely free to use. There are no paid plans listed, and API access and datasets are provided for research purposes under Ai2 terms.
Alternatives include Elicit for AI-assisted literature review, Consensus for evidence-based answers from papers, SciSpace for paper explanation, Scite for citation context, and Scholarcy for summaries.
