AI search engines go beyond the classic list of blue links. Instead of sending you to ten pages and letting you sort through them, these tools read the web, summarize what they find, and give you a direct answer with sources you can check. Some focus on general web search, others on academic papers, news, videos, or even your own files.
You can expect different approaches. Perplexity gives you fast, cited answers from the open web. Consensus and Elicit specialize in peer-reviewed research. Kagi Search offers an ad-free, privacy-focused experience. You.com provides live web search for agents and LLMs. Komo AI adds deep research and people search. Pick the one that matches the kind of questions you ask most.
