Optimal Workshop is a suite of information-architecture research tools (Treejack (tree testing), OptimalSort (card sorting), and Chalkmark (first-click testing)) with visual reports and Figma integration.
Free plan available. Starter ~$199-249/user/month (annual, unlimited users, 2 live studies, 5 studies/year). Higher tiers for more studies and advanced features.
UX researchers specifically validating navigation and information architecture (site structure, menu labeling) rather than general usability testing.
This is specialized for IA validation (card sorting, tree testing). For broader usability or prototype testing, a tool like Maze or UserTesting is a better primary fit, with Optimal Workshop as a complement for structure-specific studies.
User research and insights platform.
