Perplexity is the benchmark for AI search. It offers sentence-level citations, conversational follow-ups, and file uploads. It creates deep research reports. Korean source coverage is limited, so pair it with other tools for local topics. Pro searches have daily free limits.
Google AI Mode lives right inside the search tab, connecting directly to Maps and Shopping without extra sign-ups. Sources appear as link cards above regular results. Conversation tracking is basic, citations are not sentence-level, and regional rollout varies.
Genspark is an agent-based search tool that turns results into organized pages, reports, and slides. Perfect for market research. It uses credits, so free limits drop fast with advanced tasks, and sources need checking. Supports Korean UI and custom agent tasks.
Kagi is the only paid, completely ad-free search engine here. It blocks top ads, spam, and trackers, letting you downrank low-quality domains. Free trial is capped at 100 searches, the $5/month plan gives 300 searches, and Korean local coverage is quite low.
Naver AI Briefing delivers Korean summaries on top of search results. Sourced from domestic blogs, cafes, and news, it excels at local info like clinics and dining without login. It does not trigger for every query, and deep follow-ups work better via CLOVA X.
Choose an AI search engine based on how it displays sources and its Korean source coverage. For assignments needing citations, pick Perplexity. For Korean local info, choose Naver AI Briefing. For familiarity, use Google AI Mode. Pick Genspark for slides and reports. Always verify original source links for key figures.
