Kagi has been by far the best search experience for me. It does cost some money but damn is it nice! Even has a feature to specifcially search only in fediverse. Also a plus supporting them considering they're bringing their Orion browser to Linux.
Ok maybe I'm too pedantic, but I've see this before and it really bothers me how inconsistent information is presented here.
Granted, the country flags are somewhat self-explanatory and we get a legend for E, S, and O.
But what do the grey symbols under Searxng and Metager mean? That They are metasearch engines? That info is already communicated by being in the corresponding box.
What is the dark circles under Quant, Ecosia, and Startpage? I don't see any section that specifically refers to those three.
The tie of the differently colored names to the "to note" section is also not immediately clear.
I agree about the readability. I think the circle under Searxng and Metager is to specify they are aggregators that base their results on those that existing engines would produce. It's very hard to see, but the other circle you mentioned is a REALLY little EU flag. I think that means hosted/owned by an EU company.
Duckduckgo already does, qwant and ecosia are making an index for AI, kagi is an AI company as far as know and the already have it integrated, brave search has an AI too, startpage has an AI service, mojeek has an AI summary feature
Startpage is the only one(excluding open source) that i couldnt find anything about AI
