Our verdict on kardSort
kardSort is a browser-based UX research platform for designers, product teams and researchers running information-architecture studies. It combines open, closed and hybrid card sorting with tree testing and first-click testing, then adds questionnaires, participant segmentation through Power Filter and built-in analytics. Study links support seven participant languages and mobile-friendly interfaces. The platform is suited to teams that need one web service for varied sorting methods, remote participants and detailed UX metrics, including studies with up to 1,000 participants and cards.
Pricing is structured around a free tier and three paid options. Free Tier includes full analytics, Prolific recruitment without markup and no credit card requirement, while smaller studies have limits on participants, cards and retention. Starter costs €21 per month and adds more studies and participants, AI-powered insights and priority support. Premium is €99 per year when billed annually, also described as €8.25 per month billed yearly; it includes all kardSort features, AI features and Prolific recruitment without markup. Enterprise adds multiple accounts for teams, custom integrations, dedicated support and enterprise-grade security. This progression makes the free tier useful for initial studies, while recurring research teams can select capabilities by budget and governance needs.
Its strongest fit is a research program that values broad study coverage and analysis depth: exports include CSV, SynCaps and Casolysis formats, and paid plans add AI study analysis, normalization and study setup. Prolific recruitment is built in, but Prolific is the listed integration and deployment is cloud-based through the web. Teams needing a wider integration ecosystem or non-browser deployment should consider alternatives. Choose kardSort when multilingual participant flows, multiple test types and 50-plus KPIs matter more than an extensive connector catalog; avoid it when those ecosystem or deployment requirements are central.
