Legal professionals can now practice courtroom arguments against AI judges. BenchSim, a new legal tech tool from litigation partner Chris Ryan at Taft, Stettinius & Hollister, offers video simulations of judicial hearings. The company describes it as "an AI-powered oral argument simulation: unlimited reps, real judicial pressure, on your schedule." For lawyers who want to test arguments without the cost or risk of a real courtroom, the tool provides a structured way to build advocacy skills.
Early versions of BenchSim were text and audio-based. Using recent advances in generative AI, the platform now adds video engagement. Attorneys upload their legal briefs, and the AI digests them to run a simulated oral argument. The process is designed to mimic the pressure of real questioning.
How the simulation works
Users start by uploading up to five documents per session, each up to 20 MB. BenchSim extracts key facts, parties, and legal issues to produce a case digest of 400 to 750 words. The original document is deleted from temporary storage within seconds. The digest exists only in the user's browser during the session and is never written to the company's database.
After uploading, the lawyer chooses a judicial temperament. BenchSim offers three styles: hot, quiet, or neutral, drawn from both trial and appellate court. Each style presses the attorney differently. The simulation then runs the oral argument. At the end, the system delivers a structured critique covering strengths, weaknesses, key moments, and a score from 0 to 100.
Practical applications for legal teams
BenchSim is intended for both trial and appellate practice. The company recommends including the motion or brief being argued, along with any response or reply briefs, for the best results. The technology behind the simulation relies on Generative AI and LLM models to understand legal documents and generate realistic judicial questions.
For experienced litigators, the tool offers a way to test arguments and handle different judicial personas. Junior lawyers can use it to learn how courtroom dynamics play out without a billable case to practice on. Even if a new associate rarely appears before a judge, the simulation helps them understand how arguments unfold in real matters.
Privacy and security
BenchSim emphasizes that uploaded documents are not retained. The AI extraction service reads each file briefly to generate the digest. "The original document is deleted from our temporary storage within seconds of extraction," the company states. The digest is held only in the browser during the session and is never written to the database. Closing the browser session ends its existence on the system.
Why this matters for legal professionals
Oral advocacy is a skill that improves with deliberate practice. BenchSim provides structured, repeatable simulations that fit a lawyer's schedule. For firms looking to train associates or for partners preparing for a high-stakes argument, the tool removes the logistics of coordinating mock panels. It also lets attorneys test how different judicial styles affect their presentation - a practical advantage in jurisdictions where judges are known for their approach. As AI continues to evolve, tools like this will likely become a standard part of courtroom preparation.
