AI-First Engineering Simulation
Your AI Engineering Assistant
Backed by Physics. Driven by Conversation.
Simthetic pairs your physical model with an AI assistant that can run simulations, tune controllers, and iterate autonomously — in seconds, not hours.
Trusted by engineers across industries
What You Can Ask
Simthetic's AI assistant understands your system. Here's what engineers are already doing with it.
"Tune a PI controller for 20ms settling"
The AI assistant characterizes your plant, applies IMC methods, and validates the closed-loop response — all in a single conversation.
"Sweep input voltage from 18V to 40V and plot V_out"
No scripting. No test vector setup. The AI generates the sweep, runs the simulations, and returns a ready-to-use characterization report.
"What happens if the load drops to 1Ω suddenly?"
Ask in plain language. The AI runs the transient scenario, identifies any instability, and flags whether your controller survives the edge case.
"Validate against the detailed physical model"
The AI runs back-to-back comparisons between the ROM and your high-fidelity model, computing RMSE and flagging any regime where accuracy degrades.
"Deploy this to an MCU at 10kHz"
Simthetic generates optimized C-code, estimates CPU load, and validates real-time feasibility — from model to embedded target in minutes.
"Run this as a digital twin in the cloud"
Stream live system data into a cloud-hosted ROM for real-time monitoring, predictive maintenance, and virtual sensor replacement.
How It Works
From physical model to AI-driven simulation in four steps
Connect Your Model
Provide your detailed physical plant model. Simthetic handles the rest.
Simthetic Builds Your ROM
An automatically trained and validated Reduced Order Model — 5–100x faster than your original, with <2% error.
Your AI Assistant Takes Over
Prompt it to run tests, tune controllers, sweep parameters, and explore edge cases — autonomously.
Export & Deploy
Validated C-code ready for embedded hardware, HIL tests, or cloud deployment as a digital twin.

Versatile technology for diverse engineering challenges
Why Simthetic?
ROMs execute orders of magnitude faster than physics-based models, enabling real-time AI interaction.
Engineers provide a physical model and get an AI-ready simulation environment as output. No machine learning knowledge needed.
From cloud servers to 8-bit microcontrollers. One model, any deployment target. C/C++ code generation with full compliance.
The AI assistant doesn't just run simulations — it interprets results, proposes changes, and iterates autonomously toward your goal.
