Append a "?" to the end of the kagi query. It runs what appears to be a ChatGPT RAG query backed by a search engine index, and puts the results at the top of the normal search engine result page. It greatly outperforms any other LLM I've played with, and, as a bonus, each paragraph in the response contains working hyperlinks to primary sources.
If you don't want to pay Kagi or login, you can play with it here:
(no need to append "?" when you run queries through that form).
