About LitSource

LitSource is an AI-powered citation discovery engine for verifiable literature evidence.

Our mission

Help researchers verify any claim in seconds with real, citable evidence from trusted biomedical literature.

Tight deadlines for grants/IRB/protocols. You need defensible citations fast, without combing through dozens of tabs.
Systematic reviews that require transparency. Keep filters, provenance, and context visible so inclusion/exclusion is auditable.
Clinicians and students who need zero hallucinations. Every result links back to the original paper with the supporting sentence highlighted.

Sentence-level semantic retrieval across 30M+ biomedical papers to surface passages that support your claim.
Evidence-first reading experience: open the paper with the key sentence highlighted and expand surrounding context before you cite.
Quality signals at a glance: journal quartile/impact, citations, and recency, plus filters by year and section (Introduction/Methods/Results/Discussion).
One-click citations: copy or export APA/MLA/BibTeX/EndNote formats directly from the evidence view.

Researchers preparing grant proposals, IRB submissions, or related-work sections.
Evidence reviewers who need traceable filters for inclusion/exclusion.
Clinicians and medical students who want guideline-aligned papers without hallucinated references.
