User-centred design
for the age of AI
Stunt Double sends AI actors through your designs, prototypes, and live products, reporting back with expert perspectives.
Understand your users, before and after you ship
Stunt Double stands in for your users at every stage, turning questions about your product into answers you can act on today.
Know before you build
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.
Catch problems before your users do
Every change is checked against your requirements automatically, with the screenshot and the plain-language reasoning behind each pass and fail.
Ship changes that move the metric
Optimise toward the outcome you actually care about, then see exactly what moved it, so you iterate on evidence instead of opinion.
See your product through their eyes
A cast of users browses from the regions, devices and locales you serve, surfacing the friction you would never hit on your own setup.
A stand-in for your users at every stage
From early interviews to automated checks to behavioural optimisation, Stunt Double gives you user-grounded feedback at every stage of the process.
