From a long list to a clear priority

What matters most?

Build a MaxDiff study. Ask people to choose what matters most and least. See which items rise to the top.

Your study

Draft

Start with one decision and a list of comparable items.

This file works offline. Responses stay in this browser unless you export them. Use Export project to keep a portable backup. It does not collect responses through a shared web link.

A better way to prioritize

Small choices.
A clearer picture.

People make repeated tradeoffs between small groups of items. Together, those choices reveal relative priorities.

—items

—questions

—views / item*

*Average per respondent. A suggestion of roughly 3 appearances per item is a starting point, not a sample-size guarantee.

What this prototype measures

Choose exposure-adjusted counting scores or an aggregate MaxDiff logit model. Both summarize relative preferences within your tested list; neither establishes purchase probabilities, market shares, or willingness to pay.

Designs aim for balanced item appearances, varied pairings, and a connected comparison network. This is a heuristic design generator, not a certified optimal-design engine.

Aggregate logit estimates one shared preference model for the selected respondents. Hierarchical Bayes and individual utilities are not included. Comparing predefined respondent groups is supported; discovering segments is not.
