Thanks for mentioning. Interestingly, I recently tested several systems with identical questions (https://www.perplexity.ai/, https://www.phind.com (formerly beta.sayhello.so). The Kagi beta is sometimes on par, sometimes much better. Try [ what guests who are not actors were interviewed by smartless podcast ]. Most gives a mix of actors and non-actors, but Kagi's both Web+AI and AI sections provides correct answers.
This is fun. I tried this prompt: "Should I become a paying customer of Kagi?"
I like how it links references to support the arguments. It even gives cons and one of the sources is a HN thread from 2016! [1] It's not there yet though, because that one was about the now defunct online store platform and payment processor.
On the other hand, maybe it's my fault. I didn't specify that I meant Kagi the search engine. But it's promising.
