AI assistants invent references that look perfect: real author names, a real journal, a plausible DOI, and no paper behind them. Phở Research Tools lets your assistant check its own work against the public scholarly databases before you see it. Verify references. Paste a reference list in any style, BibTeX or RIS. Each entry comes back verified, real but with wrong details (with the corrected record), retracted, likely fabricated, or not found, with the database record it was checked against. Format citations. APA 7, MLA 9, Chicago, Harvard, Vancouver, IEEE and AMA, or export BibTeX, RIS and CSL-JSON. Verified references are formatted from the real record, so the bibliography carries the corrected details. Search papers. OpenAlex and PubMed, filtered by study type and year. Every result has a DOI or PubMed ID that resolves; retracted papers are left out and preprints are labelled. Check retractions. Retraction, expression-of-concern and correction notices for a list of DOIs. PRISMA 2020 flow diagram. Draws the diagram from your counts and warns when the numbers do not add up. No account needed. The tools are read-only lookups in public databases; they cannot read your chats or files, and there is no record of who checked what.
