Kagi Review 2026

Paid, ad-free, privacy-respecting search engine with built-in AI assistants and a developer search API.

Kagi (pronounced kah-gee) is a subscription-based search engine that has quietly become one of the most respected alternatives to Google for power users. Because Kagi sells search instead of ads, it can rank results by relevance, demote SEO spam, surface authoritative sources, and offer features like personalized site weights, lenses (custom search verticals), and the ability to permanently block low-quality domains from your results. On top of search, Kagi bundles The Assistant, a multi-LLM chat interface that lets paid users talk to GPT-4-class, Claude-class, Gemini, and several open models without separate subscriptions; an FastGPT instant-answer endpoint; and a Universal Summarizer that can read articles, PDFs, and YouTube videos. For developers, the Kagi Search API exposes Kagi's high-quality web index for use in RAG pipelines and agent tools, with usage-based pricing that is competitive with SerpAPI-class providers. Consumer plans include Starter ($5/mo, 300 searches), Professional ($10/mo unlimited search + Assistant), and Ultimate ($25/mo with premium models and higher limits). Family plans share access across household members. Kagi is popular among researchers, engineers, journalists, and AI builders who want better signal-to-noise in their searches and a privacy posture that rules out third-party ad tracking.
