Infrastructure that powers the
AI-native law firm of the future.
LexSims provides the primitives—legal actor modeling, jurisdiction environments, case execution, outcome intelligence. You compose them into whatever legal simulation your organization needs.
Composable primitives for any simulation.
Six core services that compose into any simulation product. Use them independently or orchestrate them together.
From question to strategic intelligence.
The tools to build on the infrastructure.
Visual interfaces on top of the primitives. Design simulations without writing code, or go deeper with the APIs.
Design cases visually
Configure jurisdictions, legal actors, case parameters, and triggers through an intuitive builder. No code required.
Craft legal actors
Build legal actor profiles calibrated by judicial philosophy, argumentative style, and decision patterns. Scale across any case type.
Start from what works
Pre-built case simulation blueprints across practice areas. Fork, customize, and deploy in minutes.
See what matters to you
Build your own output views. Choose which KPIs, confidence metrics, and outcome distributions to surface.
One platform. Every practice area.
Legal teams across practice areas use LexSims's infrastructure to build case simulations tailored to their exact litigation needs.
Litigation outcome modeler
Model jury behavior, witness impact, and settlement dynamics across case strategies.
Regulatory compliance engine
Simulate compliance scenarios across evolving regulatory frameworks and jurisdictions.
M&A legal risk assessor
Evaluate antitrust challenges, regulatory approval paths, and deal structure risk.
Patent dispute simulator
Model injunction risk, prior art strength, and licensing negotiation dynamics.
Class action exposure model
Simulate multi-jurisdiction certification paths and aggregate exposure scenarios.
Contract dispute analyzer
Model force majeure claims, breach scenarios, and arbitration outcome paths.
Antitrust risk modeler
Simulate merger review outcomes, remedies assessment, and competitive impact analysis.
Securities litigation engine
Model shareholder action risk, SEC enforcement probability, and settlement economics.
Employment law simulator
Simulate discrimination claims, class certification risk, and compliance gap analysis.
Insurance coverage modeler
Assess coverage disputes, subrogation paths, and claims outcome distributions.
Environmental compliance mapper
Model regulatory enforcement risk across jurisdictions and remediation scenarios.
International arbitration engine
Simulate cross-border dispute resolution, treaty claims, and enforcement paths.
Every legal analytics tool gives you their conclusions.
LexSims gives you the simulation to reach your own.
The same way flight simulators let pilots rehearse before they fly, LexSims lets legal teams rehearse before they litigate. We provide the engine. You define what it simulates.
Stop guessing at case outcomes.
