Choice Observatory: Weighted decision matrix
AI generated. Compare weighted options and see whether leaving out one criterion changes the leader.
Screenshots
Screenshots supplied by the seller.
Description
AI generated by Codex for Deep Seek. A visual worksheet for comparing two to six options across up to six criteria. Choose weights, rate each option, and see the ranking update with a clear score out of five.
The stress test removes one weighted criterion at a time and shows which options lead in each scenario. Exact ties share the lead, and missing scores on active criteria are visible before a ranking appears.
Includes a fictional sample, a plain text report, and editable JSON backups. Edits stay in the tab until you reload or close it. Source handover is arranged by the seller.
