I was skeptical at first though let me tell you, Kagi is so much better. I get exact search terms, which is immensely useful as a programmer, rather than providing results for what Google thinks I want to search for. It's also really, really nice not seeing ads as search results anymore, ad blocker or no ad blocker.
Is it as comprehensive as Google search? It meets about 95-96% of my needs. I still use Google very infrequently for some really obscure domain specific searches if Kagi doesn't find anything useful, though that's getting rarer and rarer.
It's also easy to block AI generated sites that pop up providing just enough likeness, but really are regurgitated AI trash, or are 'Wikipedia clones'.
I have no financial interest in Kagi, other than paying to use it. It has certainly been worth it for me.
Same here, still on Windows 10 though it's desperately trying to reinstall it's crapware removed from the image with NTLite.
Will be switching to some flavour of Linux at some point (we also use this PC for some Steam games), so I'll check SteamOS out!
