AI-powered answer engine that searches the live web and cites every source
Paid, ad-free search engine with an AI assistant, universal summarizer, and translator layered on top of independent search results
Kagi is a paid, ad-free search engine that adds AI features — Kagi Assistant, Universal Summarizer, and Kagi Translate — on top of independent, non-tracking search results. There is no permanent free tier, only a 100-search trial; Starter costs $5/month for 300 searches, Professional is $10/month for unlimited search, and Ultimate is $25/month for unlimited search plus premium AI models like Claude and GPT. Best for people who want search without ads or tracking and are willing to pay directly instead of being the product.
Kagi is a subscription-funded search engine built as an alternative to ad-supported search. Instead of monetizing queries through advertising and tracking, Kagi charges directly for search access, which lets it ship features ad-funded engines generally avoid — user-controlled result ranking, the ability to permanently boost or block specific domains, and a results page with no sponsored listings. Kagi Search is the core product; a one-time trial of 100 searches lets a new user evaluate it before any plan is required.
Layered on top of search, Kagi has expanded into a small suite of AI features: Kagi Assistant is a chat interface that queries multiple AI models and grounds its answers in live Kagi Search results rather than relying solely on a model’s static training data. Universal Summarizer condenses articles, PDFs, and videos into short digests, and Kagi Translate handles text, page, and voice translation across 240+ languages, with mobile apps and a browser extension for on-the-go use. The premium Ultimate tier adds a Research mode and access to flagship models including Claude, GPT, and Gemini.
Kagi is aimed at people who have decided the trade-offs of free, ad-funded search — tracking, sponsored results, algorithmic ranking they can’t control — are worse than paying a monthly fee for a cleaner result set. It is a harder sell for casual users who are used to search costing nothing, but a natural fit for anyone already paying for privacy tools or professional research software.

| Pros | Cons |
|---|---|
| No ads and no tracking by design — the business model is subscriptions, not advertising, so incentives are aligned with the searcher | No lasting free tier — only a one-time 100-search trial, so paying for search is a hard sell against Google or Bing, which are free |
| Users can customize and permanently boost or block specific domains from their own results, which ad-funded engines don't offer | Starter plan caps out at 300 searches and 300 AI interactions per month, which heavy users will exhaust quickly |
| Kagi Assistant grounds answers in real Kagi Search results rather than relying purely on a model's training data | No native shopping, maps, or local-business search parity with the largest ad-funded engines |
| Ultimate plan bundles unlimited search with access to multiple premium AI models (Claude, GPT, Gemini) under one subscription | Premium AI models and Research mode are locked behind the $25/month Ultimate tier, not available on cheaper plans |
