Setting up Kagi is as big an improvement to search as an ad blocker is to your general internet experience. After about a week you forget how bad the bare experience is, and after a month you'll never go back.
I'm definitely behind some of my peers on adopting LLMs for general knowledge questions and web search, and I wonder if this is why. Kagi does have AI tools, but their search is ad free and good enough that I can usually find what I'm looking for with little fuss.
