Show HN: I built an AI-powered advert – is this the future of advertising?

I've been thinking about how AI will change advertising. Instead of static banners or landing pages, what if an ad was a conversation? I built a demo to explore this: a fictional luxury EV brand called Vela, with an AI sales consultant named Stella you can actually talk to. Ask her about range, pricing, comparisons to competitors — she knows the product inside out. Try it here: https://99helpers.com/tools/vela-chat The idea is simple: instead of cramming everything into a hero section and hoping someone scrolls, you let the customer ask what they actually care about. The AI handles objections, comparisons, and details on demand. Built with my own platform (99helpers.com) which lets you give an AI chatbot a knowledge base and embed it anywhere. This is one use case I hadn't fully considered until recently — using the chatbot not for support, but as the ad itself. Curious what HN thinks. Is conversational advertising compelling, or just a gimmick?
