Not another writing tool. An evidence navigator.
Jenni writes papers. Vivli shares trial data. LENA finds, validates, and packages health evidence you can trust — across 11 sources at once.
11 databases, one question
PubMed, Cochrane, OpenAlex, Semantic Scholar, Europe PMC, trials, WHO, CDC, DailyMed, DSLD, and openFDA — queried in parallel.
PULSE cross-validation
Claims are corroborated across independent sources. Confidence scores show agreement — not black-box AI guesses.
Shareable evidence briefs
Export PDFs, copy full research summaries, or share a link. Built for clinicians, researchers, and health creators.
Supplement & product research
