Summary

LitSource is an AI-powered biomedical research tool that verifies clinical claims and finds supporting citations from a database of over 100 million papers.

What is LitSource?

LitSource is an AI-powered literature verification engine designed for the medical and life sciences fields. It allows users to input clinical claims or research hypotheses to find and verify supporting evidence from a database of over 100 million biomedical papers.

Key Features
  • Semantic Search: Processes clinical PICO questions or research hypotheses to match relevant biomedical evidence without requiring complex Boolean queries.
  • Citation Verification: Cross-validates reference lists against PubMed and CrossRef to identify fabricated or mismatched citations.
  • Sentence-level Extraction: Parses full-text sources to highlight specific sentences that support a user's research query.
  • Biomedical Entity Recognition: Automatically extracts and maps relationships between diseases, genes, drugs, and populations within research papers.
  • Reference Management Integration: Supports one-click PDF downloads from PMC and exports to formats including EndNote, Zotero, Mendeley, BibTeX, and RIS.
  • Data Foundation: Integrates with PubMed, CrossRef, OpenAlex, and Semantic Scholar, with data synced daily.

Key Highlights

  • Searches a database of over 100 million peer-reviewed biomedical papers
  • Supports cross-validation of DOIs against PubMed and CrossRef databases
  • Extracts specific supporting sentences from full-text documents
  • Identifies and maps biomedical entities including drugs, diseases, and genes

Does the platform support non-English language queries?

Yes, the system supports non-English inputs, such as Chinese, by automatically converting them into English search queries to retrieve relevant global literature.

Which reference management tools are supported?

Verified references can be exported to EndNote, Zotero, Mendeley, BibTeX, and RIS formats, or formatted in styles including APA, MLA, Harvard, and Vancouver.

How does the credit-based billing system work?

Each successful multi-angle search or single-paper citation verification costs 1 credit. If the system finds no qualifying results, no credits are deducted.
