Conjoint Analysis Design Tool

Plan and generate a choice-based conjoint design, then export a programming-ready block for the MX8 Labs Research Platform.

1. Study setup

Study nameUsed in your export so your team can identify this study.Forced-choice question wordingThe exact question shown immediately above each set of options.Number of attributesHow many decision factors are shown (for example brand, price, delivery speed).Maximum conceptsHard cap for generated concepts. Default is 50; max is 150.

Save or import JSON

Import JSON

A planner-setup file restores an editable study. A completed-design file preserves and scores task sets generated elsewhere.

Import a completed design

Use this route when Sawtooth, another design system, or an existing programming matrix has already created the concepts and tasks.

Give the conversion prompt and your source design to an AI assistant.
Check the returned JSON against the example or schema.
Import it here. The planner validates references, preserves task order, and calculates design efficiency.

Conversion promptInstructions for converting an existing design without changing it.Example JSONA small completed design showing the required structure.JSON SchemaThe machine-readable validation contract.

2. Generate concept pool

Reliability targetHigher reliability improves estimate stability but may reduce feasible concept count.

Planning target per segment

200

Calculated minimum: 42 · typical planning range: 200–300

3. Define levels

No exclusions configured.

5. Export design

Generate a concept pool in section 2 to enable export.
