Overview

Product summary

Review the store description, core capabilities, and common use cases.

Not all research is created equal — some studies are rigorous and trustworthy, while others raise red flags. Research Paper Checker helps you tell the difference instantly. With one click, it analyzes a research paper’s webpage or PDF and shows you whether it looks credible or suspicious.

What it checks

DOI & Metadata – Finds DOIs, titles, and journals from page content or embedded in PDFs.

Indexing – Looks up the study in Crossref, OpenAlex, and PubMed to confirm if it’s properly indexed.

Retraction Flags – Detects if the study has been retracted via Crossref or OpenAlex signals.

Trial Registration – Searches ClinicalTrials.gov and scans text for registry IDs (NCT, ISRCTN, EudraCT, etc.).
