The Verdict
Kagi is built for privacy conscious users and developers, with a focus on ad-free-search and ai-summaries. Spark targets professionals and small teams and leads with smart-inbox and ai-writing.
Pricing is close: Kagi starts at $5/mo versus $7.99/mo for Spark — not a deciding factor on its own.
Spark 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.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
