The Hallucination Problem. Solved.
The Problem with AI Legal Research
ChatGPT and other AI tools frequently hallucinate fake legal citations. Lawyers have been sanctioned. Students have failed. Careers have been damaged. Using AI to check AI doesn't solve the problem.
Real Consequences
In Mata v. Avianca, lawyers were sanctioned for citing AI-generated fake cases. This isn't theoretical - it's happening in courtrooms right now.
Our Solution: Deterministic Verification
Veridictum uses database lookup against 14.2 million real court records. Every citation is verified deterministically - no AI guessing, no probability scores. A case either exists in the database or it doesn't.
Works Where You Work
Don't change your workflow - add verification to it. Use Veridictum inside ChatGPT, Claude, or Microsoft Copilot. Upload documents on our web app. One subscription covers all.
