I feel sorry for Kagi. I've paid for the last couple of years as I support a better web search.
But I've found my web searching is so small now with AI.
I checked and I did less than 300 Kagi searches last month so downgraded my plan.
I wish them the best but timing is a b**.
I use Kagi's search API with my agents, including their summarizer, and it has been great!
I think their Kagi Assistant is quite fine for AI search. Free models, or cheap ones perhaps, but for search all are great. With some privacy benefits. I even use to cross-check the findings of Claude, which sometimes pays off! (new angles, discrepancy in important details to dive into, ...)
Beside search, I found out assistant is worth trying.
