Find Biomedical Evidence in Seconds. Verify Every Clinical Citation.Verifiable Sources
Back your clinical claims with PubMed-verified evidence.LitSource searches 100M+ biomedical papers from PubMed and CrossRef to find traceable citations for your systematic reviews, clinical studies, and medical manuscripts.
Integrated with leading academic databases
See Rigor Redefined in Action
From sourcing clinical evidence for your systematic reviews to detecting AI hallucinations in your medical references. Two core engines purpose-built for biomedical research make your manuscripts submission-ready.
Beyond Basic PubMed Search. The AI Engine for Biomedical Research.
Stop drowning in PubMed's 35 million records. From PICO-based clinical queries to AI-powered citation verification, we streamline your systematic review workflow to make every biomedical claim bulletproof.
Semantic Search That Understands Biomedical Research
Ditch complex PubMed Boolean queries. Paste your clinical PICO question or research hypothesis—AI instantly understands diseases, genes, drugs, and populations to reverse-match precise biomedical evidence.

Frequently Asked Questions
Have another question? Contact us at support@raphael.app
How accurate is citation verification? How do you ensure these aren't AI-fabricated?
We don't rely on LLMs to blindly generate results. Instead, we cross-reference your input against PubMed, CrossRef, OpenAlex, Semantic Scholar and other authoritative databases in seconds. Our core algorithm locates and highlights real supporting sentences, eliminating AI hallucinations at the source.
Is my research data and drafts safe on LitSource?
Academic privacy is paramount. LitSource uses end-to-end encrypted transmission (SSL/TLS) to protect your data. Your unpublished drafts, outlines, and search history are never used to train any external public models. You retain full intellectual property rights.
Which databases does LitSource cover? How often is data updated?
We integrate major global databases, covering 100M+ biomedical and life science papers, PMC, CrossRef, and more. Data syncs daily, ensuring the latest publications and Online First research are available for immediate search and verification.
Does it support non-English claims?
Yes. With our built-in bilingual cross-referencing model, you can input claims in Chinese or other languages. The system automatically converts them into precise English search queries to retrieve global literature.
Which reference management tools are compatible?
Export verified references directly to EndNote, Zotero, Mendeley and other major tools, or export in standard BibTeX and RIS formats. We also provide APA, MLA, Harvard, Vancouver, and other standard citation styles.
How are Credits consumed? Am I charged for failed searches?
Each successful multi-angle search or single-paper citation verification costs 1 Credit. Our billing is transparent: if no qualifying results are found, no credits are deducted.
Is there a free tier? How do I get more credits?
New users receive 10 free Credits upon registration. For higher usage, we offer monthly subscription plans (great value for ongoing research) and flexible one-time credit packs with no expiration.
