Lawyer used AI to cross-examine Zuckerberg, tripling his workload

Texas trial lawyer Mark Lanier ran on just four hours of sleep before cross-examining Meta CEO Mark Zuckerberg, after his team spent the night using artificial intelligence to prepare.

Lanier told Business Insider that the AI-assisted workflow effectively tripled his team's output during the trial, which lasted over a month.

'30 hours of work' from AI assistance

Lanier described the impact of the technology in stark terms. He said: "In the 10 hours I might be working outside of court, I can get 30 hours of work done."

He compared the setup to having ten fully briefed, round-the-clock staff members who never need a break. His team used AI tools to analyse the court transcript of everyday hearings, find out what the best supportive documents were for each point, and suggest better ways to present arguments to the jury.

Boodlebox tool combines multiple AI platforms

The tool that Lanier used the most is called Boodlebox, a learning platform that allows users to combine several AI technologies, including ChatGPT, Claude and Gemini, in one place.

He helped develop a unique licence with the firm, which cost him over six figures per year. The customised solution drew on 42 years of his expertise and knowledge from his own publications to power his questions and results.

Comparing the tool to other popular AI systems, Lanier said it was like "Disney World versus a swing set in the backyard."

Meta and Google found negligent

Meta and Google were found negligent for knowing how dangerous their applications are but ignoring to inform the public about the same.
