Checks research legitimacy: DOI, indexing, trial registration, retraction flags, ethics cues, ORCID, affiliations, and PDF parsing. 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 Retraction Flags – Detects if the study has been retracted via Crossref or OpenAlex signals.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.). Ethics & IRB Mentions – Flags whether ethics approval or informed consent is mentioned. Journal Checks – Verifies if the journal is listed in DOAJ (Directory of Open Access Journals). Authors – Pulls ORCIDs and institutional affiliations from OpenAlex. Quick results you can trust Instead of making you interpret technical metadata, Paper Legit Checker gives: A Legitimacy Score (0–100) that summarizes overall credibility. A plain-language Quick Summary that explains strengths or red flags (e.g., “Claims to be an RCT but no trial registration found.”). Works on webpages and PDFs Whether you’re on a publisher landing page, PubMed entry, or directly viewing a PDF, the extension can extract key information. If a PDF doesn’t expose metadata, Paper Legit Checker scans the raw text to find DOIs, registry numbers, and ethics references. Power features for researchers Side Panel: Keep it open while browsing multiple papers; paste in DOIs/titles to check them in bulk. Right-Click Menu: Highlight a DOI or title anywhere on the web, right-click → Check this DOI or Title… and get instant results. Who it’s for Students verifying papers for assignments or theses.
