There's tons of these frontends, including SearXNG and proprietary (but very good) Kagi. Kagi are working on their own index; this will be their meat.

I am convinced LLMs are the way forward for searching, with a caveat: what they summarize isn't very relevant (it is overrated). It just gives a (hopefully accurate) semantic context. What matters is the sources it directs to. These are your links normally on top of ypur search query.
