Kagi
A paid, ad-free search engine that answers to subscribers instead of advertisers.
What is Kagi?
Kagi is a subscription search engine with no ads and no ad-tracking business model — you pay a monthly fee and it works for you rather than for advertisers. It layers AI-generated summaries and "lens" filters, like restricting results to forums or academic sources, on top of an index that's noticeably less cluttered with SEO spam than Google.
Kagi's whole premise is a bet that enough people are tired of ad-optimised search to pay directly instead. Because there's no ad revenue to protect, it can rank results purely on usefulness and let you blacklist or boost specific domains outright — something an ad-funded engine has little incentive to offer. The AI features, including summaries and the Kagi Assistant chat tool, sit on top of that core pitch rather than being the main event.
