Duplicate Publication Checker
You're in the right place. Paste your title and abstract and this check scans CrossRef, PubMed, arXiv, bioRxiv, medRxiv, Europe PMC and Unpaywall, plus our 7.9M-paper library, for prior publication and duplicate submission — with a confidence score and the matching title/DOI for each hit. The same pass also returns your acceptance-probability tier, detected field, target journals, and the topics your abstract matched. Create a free account to run it — 25 credits to start, each run costs 15 credits.
