Answers with papers you can open.

Papers searches OpenAlex, Semantic Scholar, PubMed, Crossref, and arXiv, then gives your assistant the abstract, identifiers, and a citation. If those APIs did not return a paper, Papers will not invent one.

Who it is for

Students checking a claim, researchers following a citation trail, writers who need a real source, and clinicians looking up a PMID.

Students

Ask a question and keep the DOI with the sentence you quote.

Researchers

See what cites a paper, and what that paper itself cites.

Writers

Format APA, MLA, Chicago, or BibTeX from the record the API returned.

Clinicians

Resolve a PMID or DOI to the abstract PubMed or OpenAlex actually has.
