I tried kagi for a month and the results were probably as good or slightly better than Google for 90% of searches but it completely falls apart any time you want something local or hyper-specific. It made me realize that the personalization that people hate with Google's results actually saves a ton of time because I had to retry a lot of kagi searches with additional context.

Blocking ads and trackers in your browser and then using Google without an account will get you most of the way to what kagi is doing.
