Your product, seen through every user's eyes

AI actors with real personas navigate your product, test your flows, and tell you exactly what they experience, seamlessly integrated to your workflow.

Fresh eyes

Remember seeing your product for the first time?

You know every shortcut, every edge case, every workaround. Your users don't. They see confusion where you see clarity. They hesitate where you move fast. The closer you are to what you've built, the harder it is to see what they see.

Meet your cast

Each actor has their own background, motivations, and way of seeing your product. Their own email. Their own sessions. They navigate like real users and tell you exactly what they experience.

Insights that align

01

Define your goals

Set up a project. Build actors that match the people who use your product. Tell them what to look for.

Start with what matters most: onboarding, checkout, accessibility, or anything in between.

02

Gather real perspectives

Run checklists to verify critical journeys. Start conversations to explore open-ended questions. Every finding comes with screenshots and clear reasoning.

Your actors navigate, authenticate, and interact like real users. They report what they experience, not what you hoped for.

03

Ship with confidence

Turn findings into action. Quickly iterate and improve with a trail of evidence.

Your actors stay with you. An ongoing voice for every user type, at every stage of development.

"Step 3 is confusing"
"Love this flow"
"Button too small"
"Where do I go next?"
"Works great on mobile"
