Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2).

It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
