Kagi

Kagi is a premium, ad-free search engine that places user privacy and quality of results at the center. Rather than relying on advertising, it uses a subscription model so incentives align with delivering useful answers rather than clicks. 

Key Features:

• No ads, no trackers: Designed for users who want search without clutter or surveillance. 

• Customizable “Lenses” & domain controls: Users can filter search results by topic (e.g., Forums, Academic) and boost or block specific domains.

• High-quality search index & AI-enhanced tools: Includes own crawling/index (“Teclis”), a summary feature for pages, and “Quick Answer” for direct responses.

• Privacy innovations such as “Privacy Pass”: enable search usage without linking back to the user, enhancing anonymity.
