Agentic Sites: Building Hyper Personalized Websites — Carlos Sanchez, Adobe

Carlos Sanchez types a request for a coffee machine he can use while camping, and the page assembles itself in under two seconds. Not a search result. A page, with camping appropriate machines, rewritten copy and a set of tips, generated for that one query. Adobe calls the goal an audience of one, which is the thing marketers have wanted for decades and could never afford. The site he demonstrates is a fully generated example, and the same tool will build one for any URL you hand it in about an hour. He did it to the AI Engineer site last week, and it produced a side by side comparison of two conferences on the fly. What keeps this from being a hallucination machine is how little it actually generates. Brand guidelines are strict, so the whole site becomes a corpus and retrieval grounds everything produced from it. Only certain blocks change, the hero, the product list, the navigation, the calls to action. Model choice is treated as a per site question rather than a global one, evaluated continuously across providers for accuracy and, unusually, for speed, because a page that takes six seconds has already lost. On their example the fastest configuration averaged 1.1 seconds against 4.6 for the runner up. His point is that this does not need a frontier model, since the work is choosing and arranging blocks.
