Test the audience
that matters.
Not every variant should hit everyone. Target by device, geography, visitor type, or URL, in the same prompt you use to describe the change. Segments stay attached to the experiment record for audit and reporting.
Precision without a SQL query
Growth teams should not need an analyst to run a mobile-only pricing test.
Device, geo, and visitor rules
Limit tests to mobile, a single country, returning visitors, or traffic from a campaign URL. Rules are visible before launch so compliance and brand teams know exactly who is in the split.
