CiteSentinel Launched to Detect and Prevent AI Hallucinations in Legal Citations

Legal tech startup BrentWorks has launched CiteSentinel, a platform designed to detect and prevent AI hallucinations in legal citations, including citations in biotechnology-related matters. The tool scans legal documents and flags case law, statutes, and other legal authorities that may be fabricated, misstated, or otherwise incorrect before they are filed or reach a judge.

BrentWorks co-founder Brent Britton says the platform addresses a growing problem: courts are increasingly sanctioning attorneys whose briefs include invented citations generated by AI tools. CiteSentinel is intended to verify that cited authorities are real, and it can be used on attorneys' own drafts, documents from co-counsel or support staff, and opposing counsel's filings. Britton says this also gives lawyers a strategic advantage by helping them identify nonexistent authorities in adversaries' submissions.

Unlike traditional legal research platforms that help users find more information, CiteSentinel focuses on confirming whether the law cited in a document is real. BrentWorks co-founder Brent Hunter describes it as the first in a planned series of AI-era legal products. The founders emphasize that biotechnology litigation and regulatory work are especially vulnerable because AI-generated errors could involve patent precedents, clinical trial data, FDA guidance, scientific publications, prior art, expert testimony, or licensing agreements, potentially damaging legal strategies and regulatory submissions.
