Are Your References Real?
AI tools like ChatGPT hallucinate citations. We catch them instantly.
The Problem: Fake Citations
Recent research shows that ChatGPT, Claude, and other generative AI tools generate fake academic citations in 10–30% of cases.
These "hallucinated" references sound completely plausible:
- ✕Realistic author names and institutions
- ✕Correct journal titles (but wrong articles)
- ✕Plausible publication years and volumes
- ✕Matching your citation style perfectly
Without verification, you could unknowingly cite non-existent research—damaging your credibility and grades.
Example Hallucinated Citation
Smith, J., & Williams, K. (2021).
"Neural mechanisms of quantum computing in human cognition."
Journal of Cognitive Science, 45(3), 234–251.
Problem: This article doesn't exist. The journal is real, but no such article appears in the 2021 volume.
