My main search engine is Andisearch, it was the first search engine with AI, long before the others. I like it a lot, because of it's great privacy measures, direct answers and relevant results from trustworth sources, own reader mode, summarize, watching YT Videos sandboxed in the search results, free, no ads, no trackers, no logs, no SEO crap, anonymous, aternative web searches with other privacy search engines if it don't find results (rare). PP very similar to the one of Vivaldi.
