For reliable results today it is essential to use several search engines. The one who crawls the web the longest is Google, it is therefore advisable to use search engines that use this engine, such as Whoogle or Startpage.

Even so, it is also necessary to use search engines with alternative engines, such as DDG (Bing), or search engines with several engines, such as Mojeek or MetaGer, which use their own crawlers, such as Groot or AstianGo.

Search engines that use AI are also now proliferating, but, although practical, so far none are truly privacy oriented, with one exception, the one that was the first to use this technique with AI, Andisearch, which uses its own language model, not logs, no ads, no tracking, anonymous.

You search, although more private than others, requires activating privacy in the settings, also questionable due to its other AI functionalities that it incorporates, apart from the registration requirement to use them.
