Starter builder · facts + design + the shared engine

Build an app around one decision

Name the decision, choose what can be compared, and add options with their sources. The ranking runs here on the same engine as the live apps, and you can take the finished files with you.

The one law No source, no score. A number you cannot cite does not exist here; the score field stays shut until its source is written. That rule is what makes the result worth trusting.

The decision

start here, not with features

A worked example is loaded so you can see the ranking change.
Start with the decision, not a feature list.

The values

2–4 priorities that change the choice

Connect each local measure to one of the ten shared values. That lets another person's values file carry over without inventing a match the subject cannot support.

The options

source first, score second
