A lightweight decision helper that ranks options through pairwise comparisons. Useful for prioritizing features, ideas, purchases, or tasks with less bias and more structure. Check it out!

Project started as an educational playground to mentor my students in the field of software engineering. I’ve described this more detail in Development from PM perspective post.

How it works

You enter possible choices, the app generates every unique pair, and you pick the better option each time. When complete, it builds a comparison matrix and outputs a clear ranked list from most to least preferred.

Key features

• missing preferences inferred transitively to minimize repetition, i.e. if A > B and B > C, it knows A > C;
• criterion pick option use as a north-star in a decision-making process;
• both decision matrix and ranking output are displayed at the end of the process;
• hard choice skip to postpone decisions until later;
• choice pick keyboard support.

Tech stack

• React + React Router;
• TypeScript;
• Material UI;
• Formik.

Roadmap

• sharing options set via URL;
• option set history;
• save results functionality;
• ability to pick from more than 2 options;
• Progressive Web App (PWA) support.
