Scite

Scite is a research tool that analyzes over 1.6 billion citation relationships across academic literature to classify them as supporting, mentioning, or contrasting. Rather than just showing that Paper B cites Paper A, Scite shows whether Paper B's citation of Paper A agrees with, simply mentions, or disputes Paper A's claims. This makes it possible to evaluate the strength and direction of scientific evidence quickly.

The Smart Citations technology processes the context around each citation in 214 million papers, extracting the statement and classifying the citation relationship. When you look up a paper in Scite, you see at a glance how many other papers support it versus how many contradict it — critical information for evaluating whether a finding has held up over time.

Key capabilities include smart citation analysis (supporting vs. contrasting vs. mentioning), natural language search across 214M+ papers, claim verification against the literature, citation search (find all papers citing a specific claim), integration with Zotero and Mendeley, custom dashboards, and PDF uploading for citation analysis.

Pricing: Free trial is available with limited features. Plans start from $7.99 per month (annual billing). Individual plans provide full smart citation access. The institutional pricing serves universities and research organizations at custom rates based on user count.

Limitations: Coverage is biased toward biomedical and natural sciences — social sciences and humanities have less complete coverage. The classification of citations as supporting or contrasting requires reading context and can occasionally miscategorize ambiguous citations. Database size (214M papers) is smaller than Semantic Scholar (220M) but the citation classification adds significant unique value.

Best suited for biomedical researchers, scientists, and evidence-based practitioners who need to quickly assess whether a specific scientific claim has been replicated or challenged in subsequent literature.
