What is KimiBot?

KimiBot is Moonshot AI's crawler for content that may be used to train Kimi foundation models. Moonshot documents it on the Kimi Crawlers policy page, alongside separate agents for search and user-requested retrieval.

Those roles are independent. Kimi-SearchBot analyzes pages and builds the index behind Kimi search, while Kimi-User fetches pages for actions such as summarizing a particular article. KimiBot is the training crawler. Blocking it does not, by itself, block the other two workflows.

A KimiBot hit shows that a URL was fetched for possible training use. It does not confirm that the page entered a dataset or influenced a model. KimiBot also has no documented role in live Kimi search, so the visit is not evidence that a page will appear or be cited in a Kimi answer.

Cloudflare's bot directory records the full user agent as Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; KimiBot/1.0; +https://www.kimi.com/policies/kimi-crawlers. Moonshot also publishes current KimiBot IP ranges from its policy page. This bot entry is not IP verified and has no Web Bot Auth signature directory, so the token alone should not be treated as authentication.

The robots.txt evidence is mixed. Moonshot says KimiBot uses industry-standard directives and gives examples for full-site blocks, path exclusions, and Crawl-delay. Cloudflare's directory marks the crawler as not following robots.txt, while the bot's listing leaves the status unknown. That conflict calls for log verification rather than a categorical promise.

Sites that accept possible use in Kimi model development can leave KimiBot open while still protecting private routes normally. Publishers that want Kimi search discovery without training collection can block KimiBot and set separate rules for Kimi-SearchBot. Each subdomain needs its own robots.txt policy according to Moonshot's documentation.

Relevant for AI search

Is KimiBot relevant for AI search?

Yes. KimiBot collects pages for an AI product, so what it can crawl influences how AI systems describe your brand.

KimiBot gathers public web content that can end up in the training data for large language models. Once your pages are in that set, they influence how the operator's models talk about you for that model generation. Allowing it lets your own writing carry weight in those answers; blocking it means the models learn about you from third parties instead.

How to handle KimiBot

Moonshot asks site owners to express the training preference with the stable token:

User-agent: KimiBot
Disallow: /

Its policy also supports path-specific Disallow rules and a Crawl-delay value in seconds. Do not assume that a KimiBot block applies to Kimi-SearchBot or Kimi-User; add separate groups if those crawlers also need restrictions.

Because Cloudflare's robots.txt assessment conflicts with Moonshot's stated policy, inspect requests after publishing the rule. If access must stop regardless of crawler compliance, enforce the decision at the CDN or origin. Moonshot's current IP list can help investigate claimed traffic, but this bot does not mark those addresses as verified.

Examples

  • A publisher disallows KimiBot on paid articles but keeps Kimi-SearchBot open so its public reporting can still be considered for Kimi search.
  • A documentation team uses `Crawl-delay` for KimiBot, then checks request timestamps to see whether the interval is observed.
  • An incident responder compares a claimed KimiBot source with Moonshot's current IP list instead of trusting the `KimiBot/1.0` header by itself.
