BrentWorks launches CiteSentinel to flag AI-hallucinated legal citations

By AI, Created 11:09 AM UTC, May 20, 2026, /AGP/ – Legal tech startup BrentWorks has launched CiteSentinel, a verification tool built to catch fabricated or misstated legal citations before lawyers file them in court. The company is targeting growing sanctions risk as generative AI spreads through legal drafting.

Why it matters: - Courts are sanctioning lawyers who file briefs with invented citations, creating real professional and financial risk for firms and solo practitioners. - CiteSentinel is designed to help lawyers verify that cited cases, statutes and legal authorities actually exist before a filing reaches a judge. - BrentWorks is also pitching the tool as a way to catch citation errors in documents prepared by co-counsel, contract attorneys, paraleals and opposing counsel.

What happened: - BrentWorks Inc. launched CiteSentinel, a legal verification platform focused on detecting AI hallucinations in citations. - The company described the product as one of the first dedicated tools built specifically to identify fabricated, misstated or erroneous legal authorities. - The launch took place in Los Angeles on May 7, 2026. - BrentWorks said attorneys can scan their own drafts, colleagues’ submissions or an adversary’s filing before the errors become a problem.

The details: - CiteSentinel scans legal documents and flags case law, statutes and other legal authorities that may be hallucinated or inaccurately referenced. - The tool is meant to close a verification gap created by generative AI drafting tools that can produce authoritative-sounding but fictional citations. - BrentWorks says the platform is intended to be faster and easier than traditional legal research tools, which focus on finding more information rather than confirming whether a citation is real. - Attorneys can use the tool on AI-assisted drafts before filing, on submissions from support staff or outside counsel, and on opposing filings for strategic review. - The company says the product is meant to help lawyers avoid sanctions and embarrassment before a court. - BrentWorks said CiteSentinel is more cost-effective than a single sanctions proceeding or the reputational harm that can follow a public court error. - BrentWorks was founded by Brent Britton, a technology attorney and MIT-trained engineer, and Brent Hunter, a technologist and AI pioneer. - The company said CiteSentinel is the first in a series of products it plans to release for the legal market. - More information is available on the company’s website.

Between the lines: - The launch reflects a new legal workflow problem: lawyers may be held responsible for AI-generated mistakes even when they did not personally use the tool that produced them. - Verification is becoming as important as research in legal practice, especially under deadline pressure and in mixed teams that include outside counsel and staff. - BrentWorks is positioning CiteSentinel less as a research assistant and more as a reality check for filings.

What’s next: - BrentWorks said CiteSentinel is the first product in a broader lineup aimed at improving legal work in the AI era. - The company is expected to push the platform as a risk-management tool for law firms, legal departments and solo practices.
