SimUser AI deploys AI personas — like a New User, Security Engineer, or Mobile User — to explore your live web app via real browser automation. Each persona navigates your flows, captures screenshots and video, and delivers qualitative UX feedback with NPS scores. Self-healing flows adapt automatically when your code changes. Credit-based pricing starts at $49/mo. Built for founders who ship fast and need real UX validation — not just "does the button work?" testing.
