Card sorting & tree testing, without the price tag
TreeTest AI is a free, AI-assisted research pipeline for information architecture. Run card sorts, generate site maps, and validate navigation with tree tests — all in one tool.
How it works
One pipeline, end to end
From raw content items to a validated navigation structure — AI handles the heavy lifting so you can focus on the research.
Card Sort
Upload your content items and run open, closed, or hybrid card sorts. Share a link — participants sort in their browser, no software needed.
AI Site Map
AI clusters your card sort results into a navigation structure using participant language. Review, edit, and approve before testing.
Tree Test
AI writes realistic tasks with verified paths. Collect unmoderated responses, then get a full dashboard with success rates, SEQ scores, and path analysis.
Rich Dashboards
Similarity matrices, first-click heatmaps, confusion tables, dendrograms, and more — all the visualizations you'd expect from enterprise tools.
AI Insights
Get prioritized recommendations, problem areas, and strengths — AI reads your data so you can walk into stakeholder meetings with a clear story.
Iterate & Improve
Apply AI suggestions, re-run tree tests, and track improvement across rounds. The pipeline loops until your navigation is solid.
Why we built this
Built by students, for researchers who can't afford $300/month tools
We're UX students who ran into the same wall every semester: industry-standard user testing tools are prohibitively expensive. Optimal Workshop, Maze, UserTesting — they're built for enterprise budgets, not student projects or indie teams.
So we built our own. TreeTest AI uses AI to replace the manual overhead that makes these tools expensive — generating tasks, clustering card sort data, writing analysis, validating paths. The result is a tool that does what a $3,000/year subscription does, for free, running entirely in your browser with your own AI API key.
This isn't a watered-down demo. It's the same tool we use for our own research projects — complete with unmoderated testing, real-time response collection, and publication-ready dashboards. We believe access to good research tools shouldn't depend on your budget.
