AI Agent User Intelligence
Intelligent AI agents act as users using your live product, prototypes or Figma designs, get stuck where your customers would, and report back with insights and recommendations backed by evidence.
Point Stunt Double at a question about your product and get an answer you can act on today.
Put an idea, a flow or a headline in front of lifelike users and hear their honest reaction in minutes, long before you commit engineering time to it.
Every change is checked against your requirements automatically, with the screenshot and the plain-language reasoning behind each pass and fail.
Optimise toward the outcome you actually care about, then see exactly what moved it, so you iterate on evidence instead of opinion.
A cast of users browses from the regions, devices and locales you serve, surfacing the friction you would never hit on your own setup.
Interviews before you build, checks on every change, optimisation once it is live: three stages, one cast.
Runner is your on-call assistant. Ask in plain language and it casts actors, builds checklists, runs automations and finds answers, then takes you straight to the result.
Runner knows every corner of the app and does the work for you, not just answers the question.
No forms or menus. Say what you want and Runner works out the steps.
Creates actors, checklists, interviews and automations, not just answers about them.
Sees the page you’re on, so "debug this run" or "fix this check" just works.
⌘I opens Runner from anywhere, ready for whatever’s next.
Ask from Slack, drive a run from Claude, and land the findings in Linear as issues your team can pick up.
