Free academic infrastructure\, not a product.
Semantic Scholar indexes over 200 million papers with AI-generated summaries\, citation context showing *why* a paper was cited\, and a free public API — built by the non-profit Allen Institute for AI.
Citation context is the standout: knowing whether a citation supported or contradicted a finding is far more useful than a raw count. Being non-profit and free\, it underpins many commercial research tools rather than competing with them.
