Paste a claim or topic to find candidate academic papers, or paste a DOI to look up a specific paper and see related work. Searches CrossRef, Semantic Scholar, and OpenAlex directly from your browser.
Scholarly Source Check searches three academic databases for papers that might be relevant to a claim, topic, or specific DOI you provide. It returns candidate sources — papers that exist and appear topically related. It does not check whether the specific passage in any of those papers actually supports your specific claim. That distinction matters: a citation that exists is not the same as a citation that supports what it is attached to.
This tool also searches academic literature only — peer-reviewed papers, preprints, and scholarly publications indexed by CrossRef, Semantic Scholar, and OpenAlex. It does not search regulatory text, government and policy documents, financial filings, news reporting, or other non-academic source types. If your claim concerns a regulatory obligation, a compliance requirement, or a question that depends on primary-source government or financial documents, this tool will not surface the right material — that is a different and broader evidence problem, which is what the full Epistamate engine is built to address.

crossref.org →A free, AI-powered research tool from the Allen Institute for AI (AI2), a non-profit research institute.
semanticscholar.org →An open, comprehensive catalogue of the global research system, maintained by OurResearch, a non-profit.
openalex.org →Queries run directly from your browser to each provider's public API. No query text, claim, or search term is sent to or stored by Epistamate. Results are deduplicated by DOI and title. Coverage, metadata accuracy, and availability are determined by each provider and may vary by field, publisher, and access status.
The gap between a citation existing and a citation actually entailing the claim it is attached to is the core problem Epistamate's evidence engine is built to address — at the claim level, across academic, regulatory, and policy sources, with contradictions surfaced and gaps named rather than papered over.
