Simulate the consequences before you commit.
ARS is a multi-engine reality simulation platform. It runs Monte Carlo stress-tests, game-theoretic competitive models, network diffusion, and cross-domain world models so you can see how a decision plays out across markets, teams, reputations, and policies before you make it.

What the simulation engine does
≡
Monte Carlo stress-tests
Run 50-2000 trials per option. See success probability, crash risk, and the distribution of outcomes across every branch.
⚔
Game-theoretic competition
Model how competitors, opponents, or adversaries respond to your moves with strategic retaliation dynamics.
⇄
Cross-domain world model
Coupled simulation kernels link markets, teams, reputation, policy, and health into a single coherent world state.
◎
Network & reputation diffusion
Track how trust, narrative, and belief cascades propagate through social and market networks over time.
⌘
Causal counterfactuals
See exactly what must be true for each outcome. Get influence maps and the causal chains behind success and failure.
⚑
Decision memos & action plans
Every branch produces a memo with top risks, leading indicators, trigger thresholds, pre-mortem, and a Monday action plan.
♻
Multi-fidelity pipeline
Coarse exploration, refined deep-dives, then forensic analysis. The engine narrows automatically to the branches that matter.
⚖
Calibration & track record
Log real outcomes against predictions. Build a personal Brier score, calibration curve, and accuracy timeline over time.
⛨
Safety & guardrails
Subscription-based limits, fairness checks, red-team harness, PII detection, and restricted-domain filters built in from day one.
You describe the decision
Scenario & context
What is happening, who is involved, what counts as success or failure.
Options (2+)
Concrete choices: pricing moves, policy changes, campaign strategies, hiring plans.
Agents & stakeholders
Competitors, voters, customers, regulators, team members with risk profiles and goals.
World model plan
Pick a preset (Startup, Policy Lab, Health Twin) or customize which simulation kernels run.
The engine returns
Branching futures
Clustered outcome timelines (Breakout, Steady Climb, Crash) with probabilities and representative paths.
Decision memos per branch
Top risks, leading indicators, trigger thresholds, pre-mortem, mitigations, and a weekly action plan.
Causal influence maps
Which drivers cause success or failure and the exact thresholds where outcomes flip.
World Model OS output
Full world state graph, intervention trace, cross-domain coupling, counterfactual versioning, and planner output.
Pricing
Every plan starts with a 3-day free trial. Cancel anytime.
