The Verdict
Exa is built for ai developers and researchers, with a focus on neural-search and content-retrieval. Kagi targets privacy conscious users and developers and leads with ad-free-search and ai-summaries.
On pricing, Kagi is the clear winner for budget-conscious users — starting at $5/mo compared to $100/mo for Exa. That $95/mo difference adds up quickly for growing teams.
Exa has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Kagi requires a paid subscription from day one.
Kagi edges out on user ratings (4.6 vs 4.2). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Both tools are a solid fit for researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Kagi has a slight overall edge — but if semantic search beyond keywords matters most to you, Exa may still be the right call.
