OptimalSort is an online card-sorting tool for UX, product, content and research teams working on information architecture. Researchers can add cards or import them from a spreadsheet, invite participants through links or recruitment options, and run open, closed or hybrid sorts. The tool fits projects involving website, app, dashboard and knowledge-base structure, including navigation, labels and other organized content. Participants can create categories in open sorts, use researcher-defined categories in closed sorts, or combine both approaches in hybrid studies.

Pricing is organized around Starter and Enterprise plans. Starter costs $199 per month when billed annually and includes five studies launched per year, unlimited seats, unlimited participant responses per study, all tools and study types, AI-powered analytics and insights, and SOC II / GDPR compliance. Enterprise adds custom study bundles, unlimited seats and responses, enterprise-grade security, multiple workspaces, private projects and administrator controls. The product’s analysis depth is a central differentiator: results can include dendrograms, similarity matrices, PCA, participant-centric analysis, standardization grids, 3D cluster views, session replay and exportable results.

OptimalSort runs as a cloud service through the web and connects with Figma, Google, Okta, OneLogin, SAML 2.0 and the Optimal API. SSO and administrator controls support organizations that need managed access, while SOC II and GDPR compliance address stated security and privacy requirements. Email and documentation are the listed support channels. Teams seeking detailed qualitative and quantitative views of card groupings should consider OptimalSort; organizations needing a free option, more than five Starter launches annually or a native desktop or mobile application should choose an alternative.
