Option Comparison Calculator

Build a transparent option-comparison calculator for evaluating up to five choices against weighted criteria. Everything can run in the browser without an account.

Let users name options, define criteria, assign each criterion a 0–100 weight, and score each option from 1–10. Normalize weights automatically and show the calculation formula. Present ranked results, a criterion-by-criterion table, and a sensitivity control that demonstrates how changing one weight affects the ranking. Let users download or print the result.

Use a technical, legible interface with cream, ink, and amber. Never pretend the highest score is objectively correct. Make assumptions visible and explain that the tool structures judgment rather than replacing it.
