The AI searches have the same problem as their regular searches: it's overrun with trash, except now it's going through an AI first. Why would I pay for that?
I'd be happy to pay for an AI search engine that <i>isn't</i> controlled by advertisers. That's why I pay for Kagi. No way in hell that I'm going to pay a company with an advertising-driven business model, no matter how fancy their AI is.
