I actually like AI mode in Google. My main reason is if I just have a quick question it seems a lot quicker than logging into ChatGPT/Claude as I can just type it in the address bar.
Of course DDG / others can do the exact same thing as they already have an AI mode. Maybe you can even set up ChatGPT as a search engine - not sure. The key for this use case is speed - it has to be nearly instant.
If you could use something like a ddg bang for it? like !chat at the end of the search and it goes to some router?
Kagi does this really nicely, you just add a question mark at the end and it'll add on top of the search results an LLM summary of what's been found. It's subpar in quality but more than enough to aggregate the results by theme
