I really wanted to like Kagi, and admittedly my experimentation did not last long, but contrary to the experience of other commenters, I found Kagi search results to be significantly worse than Google. Maybe it was just the specific subjects I was searching. The final straw for me was when I searched for air quality in my city, and the Kagi results were a total joke, mostly irrelevant.

I would have been happy to pay if the results were good, but unfortunately I was disappointed by them.
