🧱 Websites & web apps: 26 Jev Cases

A Jev website case is usually the same story told twice: the model picks a layout, a copy variant or an interaction, and ordinary front-end code renders it. The posts collected here are the public builds — landing pages, dashboards and React apps that put a decision model behind the interface.

Why it matters for the Jev use case list: web work is where the cost difference is easiest to feel. Generating a page with a chat model burns output tokens; asking a typed question about which block to show burns almost none, so the same traffic costs a fraction. Every card links to the live site the author shipped, when they published one.
