Generate a marketing website that actually teaches people what a web app does. Not just a hero and feature grid — a multi-page site with real screenshots, animated GIF walkthroughs of workflows, feature deep-dives, and progressive depth from "what is this" to "here's exactly how it works."
Especially valuable for complex apps, agentic AI tools, and anything where a static screenshot doesn't convey the value.
