AI-powered UX testing tool that simulates real user personas navigating your product to surface friction points, drop-off risks, and actionable findings before real users ever see them.

Check out the project at Devpost.

1. Create a project and define a UX flow — upload screenshots or point it at a live URL
2. Build personas from 45+ behavioral archetypes backed by OCEAN personality traits
3. Run a simulation — AI agents walk through your flow as each persona, scoring friction at every step
4. Review severity-ranked findings, per-screen analysis, and AI-generated fix recommendations
5. Go deeper — chat with personas, run voice interviews, or host a focus group

Screenshot Mode — Upload static screenshots. Personas analyze each screen and decide whether to advance, hesitate, or abandon.

Agent Mode — Point at a live URL. Personas navigate real websites via Playwright — clicking, typing, scrolling — each in an isolated browser instance.
