I've been using Kagi for over a year and a half and it's awesome. I can block entire domains (like spammy sites), there's no ads, and I see less SEO garbage. I really like how the AI quick answer is only generated when I include a "?" at the end of my search query, making it super useful for quick answers and I can dig deeper via the search results if needed. They also have a "Small Web" toggle so I can limit my search to smaller, personal websites.
