Perplexity vs Kagi

Perplexity and Kagi are two of the most popular tools in the search category, but they take different approaches to solving the same problems. Perplexity, developed by Perplexity (founded 2022), is described as "ai-powered search engine that provides answers with sources.". Meanwhile, Kagi by Kagi (founded 2021) "premium ad-free search engine with ai summaries, customizable results, and privacy focus.". Both tools share the same rating of 4.4/5.0, making this a genuinely close comparison. Your choice comes down to specific needs rather than overall quality. Both tools are priced around $20/mo, so cost isn't a differentiator here — the decision comes down to capabilities rather than budget. Neither tool is perfect: Perplexity's main drawbacks include can hallucinate sources, limited free queries, while Kagi users typically cite paid only as its biggest limitation. Both tools excel at research, so either choice will serve you well for these core use cases. However, Perplexity has an edge in fact-checking, which might be the tiebreaker if that's important to you. In terms of target audience, Perplexity is particularly popular among researchers and students, while Kagi tends to attract privacy-conscious users and researchers. Our verdict: With identical ratings, you can't go wrong with either. Try both free versions and pick the one that clicks with your workflow.
