Make your AI agent more reliable with simulation.

Go beyond manual evals and simulate thousands of realistic user interactions to find blind spots before your users do.

/1

Get started in minutes

Works with your workflow – our API and Python SDK support all major agent frameworks out of the box.

/2

Lifelike user testing

Real users don't follow scripts. Learn how your agent performs in diverse and challenging scenarios, fine-tuned to your use case.

/3

Automated interpretation

Auto-generated summaries of each simulation run including code evals and AI evals, so you can iterate faster.

/4

Monitoring & feedback loop

Our simulations adapt over time to incorporate patterns observed from your real users.
