Duplicate Publication Checker

You're in the right place. Paste your title and abstract and this check scans CrossRef, arXiv, medRxiv, bioRxiv and our 17,500-venue 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 research gaps. Create a free account to run it — 25 credits to start, each run costs 15 credits.

Need a full peer-review report with detailed agent analysis and an editorial recommendation? Use AI Review Engine instead — 8 specialized agents + synthesis, for complete manuscripts.
