Also, none of these accounts saying nice things appear to be bots or kagi-focused in any way, so I think it's safe to assume they do actually just like it.
Kagi has a free trial, but you have to pay, which is the difference between it and early Google.
Of course, now we have Google ads instead, so who knows, maybe not bots.
I am definitely not a bot.
I am however extremely fed up with Google. And equally thankful that I have found something that works as well as old Google (or better).
