Optimize your information architecture
Let participants organize content into categories that make sense to them. Run open sorts (participants create categories) or closed sorts (predefined categories) to understand your users' mental models.
Similarity matrix, dendrograms, category agreement scores
Set up your study in minutes — choose settings, add tasks, and customize for your audience.
Access our MENA participant pool or invite your own users. Real people, real insights.
View responses in real-time with built-in analytics. Export data or share with your team.
Use card sorting when designing or redesigning navigation, menus, or content categories. Run an open sort during early discovery to learn how users naturally group content, or a closed sort to validate an existing structure before development begins.
Review the similarity matrix to identify which items users consistently group together. Use dendrograms to visualize natural clusters. For open sorts, compare participant-created category names against your planned labels — high agreement means your labels match user mental models.
Combine Card Sort with complementary research methods for deeper insights.
