As answered by people managing Codility and Unit Index.
Unit Index's answer:
Unit Index is still early and does not have major customers yet.
Unit Index's answer:
Unit Index is built for quick understanding. Instead of leaving users with a number, it shows what that number feels like in the real world. A student, writer, or curious reader can type a measurement and quickly picture the scale.
Unit Index's answer:
Unit Index gives measurements a visual meaning. For example, if someone looks up 40 feet, they might see how that compares to a school bus, a telephone pole, a shipping container, or another familiar object.
Unit Index's answer:
The main audience is students, teachers, writers, researchers, and curious people who need to understand measurements visually. It is useful for anyone asking questions like “How big is 100 feet?” or “What does 2 acres actually look like?”
Unit Index's answer:
Unit Index came from the idea that measurements are often technically clear but hard to picture. The site was built to make scale easier to understand by turning numbers into concrete visual references.
Unit Index's answer:
Unit Index is built with React, Vite, Express, static site generation, SVG visualizations, and AI-assisted comparison text.
