How the top ai search engine tools compare on pricing.
10 of 11 tools offer a free or freemium plan.
Every tool here is a real, working ai search engine product. We rank on features & output quality and pricing and value (including free tiers). The list is reviewed regularly so it stays current — read our methodology for the full process.
The factor that decides everything else — can it produce ai search engine results you'd actually ship? It's why Felo leads this list; judge each tool on output you can use without heavy rework.
10 of these 11 tools have a free or freemium plan. Check the free tier's real limits and whether paid pricing scales fairly with your usage — watch for hidden caps on output or features.
A clean interface and good onboarding mean you get value on day one, not after a week of learning the tool.
Does it connect to the tools you already use — your editor, browser, Slack, Google Workspace or API?
Fast, consistent results matter for daily work. Look at uptime and how the tool handles peak-time load.
Active development, solid docs and responsive support signal a tool that will keep getting better over time.

When free is enough

When to go paid
For heavy or professional ai search engine work, a paid plan like Kagi's buys higher limits, team collaboration, priority support and advanced features. If a tool is core to your daily work, the subscription usually pays for itself in time saved.
