User Simulation
Test with realistic personas before real users
Simulates realistic user personas walking through your prototype, reporting friction points, confusion, and drop-off risks before you test with real people.
How it works
Define your personas
Describe the user types you want to simulate — or let the agent generate relevant personas based on your product context.
Run the simulation
Each persona walks through your prototype independently, reacting to the experience from their perspective.
Review the findings
Get a report of friction points, confusion moments, and drop-off risks organized by persona and severity.

Why use User Simulation
Test before you test
Catch obvious friction points before investing in real user testing sessions.
Multiple perspectives
See your design through the eyes of power users, first-timers, accessibility-focused users, and more.
Specific friction points
Each persona reports exactly where they got confused, frustrated, or would have dropped off.
Faster iteration cycles
Fix issues between simulation rounds instead of waiting weeks for the next user testing session.
When to use User Simulation
Pre-launch validation
You want to validate a new flow before launching it to real users.
Simulate 3 personas walking through our new upgrade flow: a power user, a free tier user who has never upgraded, and a non-technical user.
Accessibility perspective
You want to understand how users with different abilities would experience your design.
Simulate a keyboard-only user and a screen reader user navigating our new settings page.
Edge case discovery
You want to find edge cases by simulating users with unusual but realistic usage patterns.
Simulate a user managing 50+ projects in our dashboard. Where does the experience break down at scale?
