LLMs are not magic, nor are they gonna crawl some dozens of websites, they work with search results they are provided with, and thus they need good search results to work with. Maybe in the US or sth it is better, but where I live finding good shopping results from local shops/websites is not straightforward. Google shopping, that I just now checked, seems much better with querries that I struggled with kagi. Typically, in order to find things I need I usually run searches on local price aggregators than kagi, though it is not perfect because they do not include shops that don't want to pay them, and their search features are not great either. But running kagi for local search shopping results ime is not great, and similarly the assistant do not provide great results either.

I do not want a click-to-buy button, I want kind of lens that is specialised for shopping within specific regions (the current kagi lenses allow only 10 sites which is not really enough for shopping).
