KimiBot: what this bot is and how to allow or block it
KimiBot is a bot from Moonshot AI that collects pages to train AI models. It does not affect Kimi answers with search: you can block it without losing visibility in AI search.
KimiBot User-Agent
This is how KimiBot identifies itself in requests to your site. In robots.txt you only write the token — KimiBot.
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; KimiBot/1.0; +https://www.kimi.com/policies/kimi-crawlers
How to allow KimiBot
Add this group to robots.txt at the site root. Close service sections in the same group: a bot with its own group does not read the «User-agent: *» rules.
User-agent: KimiBot Allow: /
robots.txt is not everything. If your site uses Cloudflare or other bot protection, it may serve KimiBot a 403 error or a challenge page even when robots.txt allows everything.
How to block KimiBot
To block the whole site, add the group below to robots.txt. The rule works for bots that respect robots.txt.
User-agent: KimiBot Disallow: /
What happens if you block KimiBot
New model versions will not learn from your pages. Visibility in answers with search does not change — search bots are responsible for that.
How to check whether KimiBot visits your site
Search the web server logs for the token. The User-Agent string is easy to fake, so to be sure, check the IP address against the ranges if Moonshot AI publishes them.
grep "KimiBot" /var/log/nginx/access.log
Does your site let KimiBot in
Free 15-second check: we read your robots.txt and request your site as AI bots — you see which ones the server and bot protection let in and which they block.
Questions and answers
Should I block KimiBot?
It is your call. Blocking KimiBot does not remove your site from AI answers with search, but models will not learn about you in training either. If content is your main asset, block it; if awareness matters, leave it open.

Is it enough to allow KimiBot in robots.txt?
