I'm using Kagi every day, and unfortunately, it is not true anymore. I think what happens is that the blanket banning of IP ranges because of LLMs, and flat out incompetence and laziness, affects them heavily. I get results, or just a few unrelated ones many times every day, while Google happily returns what I searched for. I think Kagi's index is shrinking, or they really made their algorithm worse.

I slowly shifted to use LLMs because of this in the past half years, making the situation probably worse for Kagi. They were the last usable search engines for years now. I still pay for it, but it's increasingly not that useful anymore.
