Test prototypes, compare design options, and validate information architecture with people you recruit—your lab, one link or embed, any device, live site tests when you need the real thing. Get inspectable matrices and paths before engineering invests.
Test every stage of the design process
From early concepts to interactive prototypes — validate your designs with the right research method.
Validate your work, win design debates with data, and ship better products.
Upload static mockups and get user feedback in hours. Catch usability issues before they become expensive engineering problems.
Run preference tests to let users choose between options. Replace "I think" with "users prefer" and make design reviews more productive.
Card sorts and tree tests show where labels and groupings break down—similarity matrices, success rates, and path plots you can put in front of PMs and eng.
