AI writing tools frequently invent realistic-looking citations that don't exist. RefCheck catches them by checking each reference against real scholarly databases rather than trusting an AI's memory.
The process
1. Your list is split into individual references.
2. Each one is searched across Crossref, OpenAlex, Semantic Scholar, Europe PMC / PubMed and DataCite — plus direct DOI resolution — the actual registries of published works. We compare the matched record's title, authors, year, and DOI to what you wrote.
3. An AI gives an independent second opinion on authenticity, but the database evidence is the ground truth.
4. Verified references can be reformatted into any style from the real metadata.
The verdicts
Verified Found in a database with a strong title match.
Caution A real work was found, but a detail (year, journal, page, or DOI) doesn't match what you wrote.
Unverified No matching record found — possibly fabricated or AI-hallucinated. Check it manually.
Privacy
Your references go to your browser's lookups (Crossref/OpenAlex) and to Dr.AI Studio's AI proxy for parsing and the second opinion. Nothing is stored after the check.
