If you follow me on LinkedIn or spoke with me at AALL, you’ve probably seen me teasing this project like it’s the season finale of a legal tech drama. Well, the wait is (almost) over — here’s your official sneak peek at our forthcoming interactive GenAI Legal Hallucination Tracker.

The People Behind the Tracker

First, credit where credit is due: fellow law librarian Mary Matuszak, the ultimate sleuth of AI blunders. I’ve sent many curious folks her way on LinkedIn, where she’s been posting hallucinations far more regularly than anyone else. By mid-July, when she sent me this spreadsheet, she’d logged 485 entries — and yes, the number has since blown past 500. She’s basically the Nellie Bly of questionable legal citations.

Next up, my research assistant, Nick Sanctis — the wizard making the interactive tracker happen and gently forcing me to learn just enough R to be dangerous. If there’s a delay, blame my attempts to juggle teaching, running a library, staying current with AI developments, and decoding the mysteries of R this fall.

As for me? I’m the publisher, the cheerleader, and the student in this equation.

The Plan

Today we’re releasing a the basic tracker data in a sortable and searchable table format. In the coming weeks, we’ll roll out the more robust interactive version, followed by new features for viewing, filtering, and analyzing the data — each announced in its own post.

But wait! There’s more! We want you to be part of it! Soon, we’ll be recruiting volunteers to:

1. Help us find and add more hallucination cases (submission method coming soon)
2. Analyze the data and share insights with the legal community

If you use the tracker, please cite or link to it in your work. Proper attribution keeps this project alive and growing.
