The original
Semantic Scholar
A free, AI-powered search engine for scientific literature covering papers from all fields of science.
Replacements
Listings that take over the same core job as Semantic Scholar.
SciSpace
An AI research assistant for searching papers, running literature reviews and writing with citations.
SciSpace searches more than 280 million papers and adds chat with PDF, literature review and writing tools, but full features require a paid plan, unlike free Semantic Scholar.
Consensus
An AI search engine for peer-reviewed literature that gives evidence-based answers drawn from papers.
Consensus searches peer-reviewed literature and returns answers backed by papers, and moves from a free service to a freemium one with plan details not given.
Elicit
An AI research assistant that finds papers, summarizes findings and extracts data for literature reviews.
Elicit finds and summarizes papers and extracts data for literature reviews, on a freemium plan rather than Semantic Scholar's free search and public API.
Scite
An AI research tool that answers questions from scholarly articles and shows how claims are cited.
Scite adds full-text search across licensed publisher content and shows whether later work supports or contradicts findings, on a freemium plan rather than free access.
ResearchRabbit
A web tool for literature reviews that finds related papers and builds citation maps.
ResearchRabbit is also free and finds related papers from a seed paper, adding visual citation maps. It requires an account and offers no public API.
Also worth comparing
These listings name Semantic Scholar as their own alternative, so the relationship runs both ways.
Connected Papers
A web tool that draws a visual graph of academic papers related to one you start from.
Semantic Scholar gives a free search engine covering more than 238 million papers with a public API, but shows plain results rather than a visual graph of related papers.
Undermind
An AI research agent that searches the scientific literature in depth and cites every source.
Semantic Scholar is a free search engine indexing more than 238 million papers with a public API, though it is a search index rather than a research agent.
