Frequently asked questions
Does it catch fabricated citations?
It flags references that do not exist in open indexes, or whose DOI points to a different paper. It does not replace expert reading, but it catches the typical hallucination pattern.
What about retracted papers?
OpenAlex includes Retraction Watch: retracted works are highlighted in the report.
