I was concerned that I would still be semi-reliant on Google Search for things like local business opening hours etc. While it's true that Kagi doesn't return that stuff at the top of a search (I'm outside the US so YMMV), in practice it's been a non-issue because the top result—rather than an ad or some AI nonsense—is just that business' website. So at most it's one extra click.
I don't think I've deliberately done a Google search since I signed up, apart from to check that the !g option works as expected with the Safari extension (c'mon Apple, support custom search engines already)
