Kagi's AI agents and crawlers

Kagi runs one agent that visit websites: 1 AI assistant. Here's what each one does, and how to let them in or keep them out.

AI assistants

Fetches pages for a person, in real time, while they use an AI assistant. Almost always allow it. Blocking it means the assistant can't read your pages when a customer asks about you, so it answers from somewhere else.

  • kagi-fetcher: Fetches pages to answer questions in Kagi's AI search features.

Robots.txt for every Kagi agent

To block every Kagi agent that reads robots.txt. This also keeps out the ones acting for your customers and the ones that send you visitors, so think twice:

User-agent: kagi-fetcher
Disallow: /

Robots.txt is a request, not a lock, and some agents that act for a person in real time may not read it. A decision guide for blocking or allowing AI crawlers.

How to tell if it's really Kagi

Our registry doesn't verify Kagi's agents against published IP ranges, so treat a request that uses one of their names as a claim, not proof. Ghost Agent Lab reports these requests as unverified rather than guessing.

Which Kagi agents visit your site? Ghost Agent Lab reads your CDN or server logs and shows every request from them: what they read, what your site sent back, and whether each one was genuine. See agent traffic, or check whether AI agents can use your site for free.
