You Can't Foresee Every Outcome

You are responsible for dozens of business decisions a day. But the tools you have can' t keep up with the complexity of real-world operations.

Averages hide the risks

Your spreadsheet shows 80% capacity—looks safe. But it can't show you the queue building every Friday at 2pm when demand spikes 40%.

Intuition has limits

Gut feel works—until it doesn't. You're either overstaffing 'just in case' (expensive) or missing growth opportunities (painful).

Simulation is out of reach

You know modeling would help. But hiring simulation engineers for everyday decisions? Too slow. Too expensive. Never happens.

From “I Think” to “I Know” in 3 Steps

See how Text2Sim turns questions into validated answers

1

Just Ask

Brief your AI like a colleague. No coding required.

2

The Build

AI translates your words into rigorous simulation code.

3

The Stress-Test

Get probabilistic answers, not spreadsheet guesses.

Your Reality. Real Code. Real Math.

Zero hallucinations. Text2sim MCP tools force your AI to use deterministic simulation engines to build a model.

Discrete Event Simulation (DES)

Queues, logistics, call centers, manufacturing lines.

Engine: SimPy

System Dynamics (SD)

Market flows, viral loops, inventory management, feedback loops.

Engine: PySD

Core Features, Open Source

All essential simulation tools are available in the open-source MCP server. Full DES and SD engines, free to use and modify.
