As answered by people managing LeetCode and Unit Index.

Who are some of the biggest customers of your product?

Unit Index's answer:

Unit Index is still early and does not have major customers yet.

Why should a person choose your product over its competitors?

Unit Index's answer:

How would you describe the primary audience of your product?

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?”

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

Unit Index is built with React, Vite, Express, static site generation, SVG visualizations, and AI-assisted comparison text.
