12-Person AI Jury Simulation for Trial Attorneys
Traditional in-person mock trials cost $30,000 to $60,000 and take six weeks to schedule, forcing trial teams to gamble on instinct for 95% of their matters. Cleros AI delivers venue-calibrated, 12-person virtual jury deliberations in under three minutes—empowering you to test theories, opening arguments, and damages exposure iteratively.

Realistic Deliberation Dynamics Calibrated to Your Courtroom
Real juries do not compute verdict equations; they tell stories, align with emotional archetypes, and negotiate damages in a closed room. Cleros AI simulates this complex human dynamic through six interconnected analytical pillars calibrated with U.S. Census Bureau demographic datasets.
Virtual panels are sampled from ground-truth demographic, socioeconomic, and educational distributions corresponding to your specific federal district or county venue.
Simulates real courtroom social psychology: foreperson election, anchor jurors, silent conformists, and vocal contrarians who debate case exhibits point-by-point.
Measures liability split across multi-defendant matters under pure or modified comparative fault rules, delivering statistical probability of plaintiff vs. defense verdicts.
Models damages awards across bimodal curves (10th, 50th, and 90th percentiles), isolating realistic median numbers while quantifying runaway nuclear verdict exposure.
Each synthetic juror possesses calibrated cognitive biases, educational backgrounds, and localized socio-political viewpoints that dictate how evidence is perceived.
Run concurrent simulations testing different themes, storytelling arcs, or damage anchor numbers to determine which framing secures unanimous liability consensus.

Stop Guessing Case Valuation: Predictive Damages Distribution Curves
Litigation settlement decisions are often corrupted by the “average verdict” fallacy. If three simulated juries award $0, $500,000, and $25,000,000, the average is $8.5M—yet that average represents no actual juror reality. Cleros AI generates bimodal distribution models showing probability clusters under FRCP 26(b)(3) work-product protection.
Liability Bar / Low Spec
Models situations where conservative or skepticism-heavy jurors successfully argue zero fault or strictly limit recovery to incurred medical specials.
Defensible Mediation Target
Identifies the realistic midpoint where compromise jurors converge during joint compromise negotiations, establishing a firm, defensible settlement anchor.
Nuclear Verdict Risk
Exposes the combination of egregious conduct findings, inflammatory exhibits, and juror anger that triggers runaway noneconomic or punitive damages.
AI Jury Simulation & Mock Trial FAQ
Detailed insights into our statistical models, venue mapping, and work product privilege.
How are virtual mock juror personas calibrated to our trial venue?
Cleros AI utilizes official US Census Bureau demographic, educational attainment, median income, and political distributions for all 3,143 United States counties and 94 federal district courts. When you select your venue, the engine creates synthetic juror agents whose demographic markers, cognitive heuristics, and belief systems reflect your venue's real jury pool.
How does Cleros AI simulate the human dynamics of a jury deliberation room?
Deliberations occur in multi-stage conversational turns where synthetic jurors nominate a foreperson, review court instructions, debate key pieces of evidence, argue over witness credibility, and iteratively vote on liability and damages. Rather than computing static averages, the model allows dominant jurors to sway undecided members and captures genuine interpersonal debate.
Can we test multiple variations of an opening statement or damage ask?
Yes. Because Cleros AI simulations run in minutes, trial teams routinely execute A/B testing: run Panel A with an aggressive $15M life-care damage anchor, and run Panel B with a conservative $6M medical-only request. Comparing juror pushback reveals whether an aggressive figure anchored damages upward or alienated conservative swing jurors.
Are mock trial outputs admissible in court or discoverable by opposing counsel?
Cleros AI simulations are designed strictly as core attorney work product under Federal Rule of Civil Procedure 26(b)(3) and state equivalents. All simulation parameters, juror prompts, and deliberation outputs are protected under your firm's encrypted workspace and are never shared or indexed publicly.
