Semantic Scholar

AI search over peer-reviewed research papers, with inline citations.

An academic search engine that runs natural-language questions against a corpus of more than 200 million peer-reviewed papers and synthesizes the findings with inline citations. Its Consensus Meter aggregates how much the studies agree or disagree, and a copilot helps draft literature reviews. Aimed at researchers, students, and clinicians.

A free Basic plan offers unlimited search and summaries; paid tiers add data-extraction volume and the review pipeline.

AI research assistant built on citation-context Smart Citations.

Scite helps researchers find and evaluate scientific literature using Smart Citations — citations classified by whether they support, contrast, or simply mention a paper's claims. Beyond search, its AI Assistant answers research questions with grounded, cited references, and reliability dashboards flag retracted or heavily disputed work. Available on the web and via browser and reference-manager plugins.
