Kagi

Kagi Search is a user-centric, paid search engine that prioritizes the needs of its users over an advertising model. It provides users with the information they're looking for accurately and efficiently, and does not track user behaviors, sell user attention to advertisers, or clutter search results with sponsored content.

Kagi Search prioritizes user interests by implementing a unique mechanism where users can upvote or downvote search results according to their personal preferences. This allows the users to influence the search algorithm with their personal preferences, effectively personalizing their search experiences.

Kagi Search does not track user behavior. It is explicitly stated on their website that Kagi does not have any data tracking, ensuring that user privacy is maintained at all times.

The upvote/downvote mechanism in Kagi Search allows users to rank search results according to their personal preferences. When a user upvotes a search result, it means they consider it relevant and beneficial, whereas a downvote signifies the user found the content less useful. This influences the search algorithm to better suit the user's needs.

Kagi Search helps to maintain user privacy by following a model that does not track user behavior, sell user attention to advertisers, or display sponsored content. It also offers features like 'Privacy Pass', adding an extra layer of privacy by making searches unlinked to the user's account.
