Free Bibliography Checker

Verify every reference in your bibliography against three academic databases.
Catch AI-generated fake citations before anyone else does.

Why Your Bibliography Needs Checking

AI tools generate bibliographies that look correct — real journal names, plausible authors, properly formatted DOIs. They are not correct. The references are fabricated, and the bibliography passes every visual inspection.

This is not a flaw in the AI. It is how generative models work — they produce statistically plausible text, not verified facts. If you used any AI tool to help write or edit your paper, your bibliography may contain references that do not exist.

AiCitationChecker verifies each entry against CrossRef, OpenAlex, and Semantic Scholar — three independent academic databases covering millions of publications. A reference missing from all three is not a real reference.

What the Bibliography Checker Catches

  • Non-existent papers — no record in any academic database despite plausible-sounding details
  • Wrong authors — the DOI resolves to a real paper but the listed authors are wrong
  • Fabricated titles — real researchers who never published that specific paper
  • Invalid DOIs — DOI formatted correctly but leads nowhere
  • Wrong journal metadata — real journal, invented volume, issue or page range
  • Duplicate references — the same paper listed twice under different formats

How It Works

1. Paste your bibliography

Copy your full reference list. Any citation format accepted — APA, IEEE, MDPI, Vancouver, Chicago, Harvard, or mixed.

2. Automatic verification

Each reference is checked against CrossRef, OpenAlex and Semantic Scholar. Flags errors, mismatches and entries that cannot be found anywhere.

3. Fix and export

For every reference that checks out, the output is reformatted directly from CrossRef metadata — the authoritative record, not what you originally typed. Choose a citation style (APA, IEEE, Chicago, Harvard, Vancouver, MDPI) and download the full list as a Word document.
