I subscribed to the lower tier for a while, but I kept running out of searches early on every month, and the price of the higher tier is just not excusable. So I found myself adding the !ddg bang most of the time to avoid spending my Kagi quota.
And as good as Kagi is, it's still primarily a meta search engine, organizing results from the dominant actors. So it's not like the price is justified by them having to crawl the entire web themselves. Their own crawler, Teclis, is currently small web only and can probably best be described as an interesting project.
Instead of making search cheaper or more affordable, they spend subscription money on creating AI services and various other non-search distractions. Maybe that's good for some people, but I don't want that shit. I just want a good search engine at a justifiable price. And for that, sadly, Kagi fell short.
