I use Kagi too - they have a feature I haven’t seen before where you can basically optimize your own SEO. You can uprank or downrank any given website to varying degrees based on how much of that site you want to see in your future search results (I use this a lot for game wikis that have since migrated off of Fandom etc, but the stale Fandom page always shows up first in google search).
They’re also working on a feature to warn you which articles are paywalled directly from the search result, which I will use the hell out of.
They also have something they call Lenses, which are essentially search profiles that emphasize certain types of results (programming lens upranks stackoverflow, github, and API docs for instance).
All in all I’ve been extremely pleased with the quality of the product and the directions they’re exploring in. And being able to easily chat up the devs in discord doesn’t hurt either.
Since becoming an adult it has become increasingly obvious to me that early high-school level stuff is impossibly complex for a significant chunk of the population.
