Many existing card sorting platforms restrict researchers through participant limits, card quotas, or premium subscription requirements.
SortLab was created as a free and accessible alternative that enables researchers, students, and independent professionals to conduct complete card sorting studies without artificial limitations.
The goal is simple: make Information Architecture research accessible to everyone.
