Maybe you see different comments than I do, but I don't see many comments saying it's improved a lot lately.

As a Kagi user, I would not say it's improved a lot lately. It's a consistent, specific product for what I need. I like the privacy aspects of it, and the control to block, raise or lower sites in my search results. If that's not something you care about then don't use it.

Is it better than Google at finding things? I don't think so, but then, Google is trash these days too
