Kagi AI is a premium, privacy-focused search engine designed to deliver fast, ad-free, and high-quality search results with the power of artificial intelligence. Unlike traditional search engines that monetize user data and display ads, Kagi offers a clean, distraction-free experience tailored to individual preferences.
Built by a team focused on ethical technology, Kagi gives users control over what they see and how they search. It incorporates AI tools like real-time summarization, intelligent snippets, and user-controlled ranking to deliver more meaningful search experiences. Kagi is subscription-based, ensuring that the product serves its users—not advertisers.
Features
Kagi delivers ad-free search results, removing sponsored links and distractions from the user interface.
The platform features Lina AI, an assistant that provides real-time summaries of websites, helping users understand content quickly.
Users can custom-rank domains, prioritize or deprioritize specific websites, and block unwanted sources.
Kagi includes FastGPT, a GPT-powered assistant that answers complex questions with cited sources in real time.
Search results are ranked based on quality and usefulness rather than ad revenue or SEO manipulation.
The Universal Summarizer tool works across articles, videos, PDFs, and transcripts, summarizing content instantly.
Kagi supports Instant Answers for queries like definitions, conversions, and weather updates, improving efficiency.
Users can create Lenses, which are search filters designed to surface content from specific topic categories or trusted sources.

Kagi does not log user data, track clicks, or sell information to third parties.
How It Works
Kagi AI operates as a subscription-based search engine, combining multiple features into one platform focused on user experience. When a user submits a query, Kagi retrieves results from the open web, curated sources, and its own indexes, using proprietary ranking algorithms.
The platform enhances the experience with AI tools like FastGPT, which provides conversational responses similar to ChatGPT, and Lina, which offers concise summaries of web pages, PDFs, and even YouTube transcripts.
Unlike traditional engines, Kagi allows users to customize the ranking of domains, giving them more control over the type and quality of content they see. Users can also filter searches with Lenses, which refine results based on content type or topic.
Summarization tools use natural language processing to condense lengthy documents or media content into digestible overviews. All these tools are integrated into a private, ad-free environment with fast load times and a focus on utility over monetization.

Developers benefit from ad-free, high-signal coding-related queries and the ability to suppress irrelevant content.
Knowledge workers use Lenses to focus searches on specific industries, domains, or trusted publications.
Privacy-conscious users choose Kagi over traditional search engines to avoid data tracking and behavioral profiling.
Educators and researchers leverage the summarization tools to quickly digest new materials and support teaching materials.

Comparison with Other Tools
Compared to Google Search, Kagi offers an ad-free, privacy-focused alternative with better user control but lacks the full suite of Google integrations.
Unlike Bing or DuckDuckGo, Kagi is subscription-based and provides premium AI tools such as summarization and assistant features.
Compared to You.com or Perplexity, Kagi emphasizes source control, content customization, and high-trust AI summarization instead of only chat-based interaction.
Against ChatGPT, Kagi’s FastGPT integrates live web data, offering more current and sourced answers, though it lacks ChatGPT’s creative generation depth.
Compared to Neeva AI (now discontinued), Kagi has become a leading option in private, premium search, continuing where Neeva left off.
Versus Brave Search, Kagi’s AI tools and summarization capabilities provide a deeper experience, though Brave offers a free model with some privacy features.
