What is cohere-ai? How to allow or block Cohere's crawler
User-agent string to match in robots.txt and server logs: cohere-ai
Operator
Cohere
Purpose
AI model training
robots.txt
Compliance unknown
Official docs
None published
cohere-ai is the user agent associated with Cohere, whose Command models focus on enterprise use cases. The crawler is undocumented, which makes its exact behavior hard to verify — most site owners treat it as a training crawler and decide on blocking accordingly.
Does cohere-ai respect robots.txt?
Cohere publishes no official crawler documentation, so robots.txt compliance can't be verified; use firewall rules if blocking it matters to you.
Verify it's really cohere-ai
Cohere publishes no IP-range file for cohere-ai, so it can only be identified by its user-agent string — which anything can send. Treat traffic claiming this agent as unverified, and prefer a reverse-DNS check where the operator documents one before acting on it.
Block cohere-ai with robots.txt
User-agent: cohere-ai Disallow: /
⚠ Because cohere-ai's robots.txt compliance is unreliable, pair this with a firewall or CDN rule matching the user-agent string if blocking actually matters to you.
Explicitly allow cohere-ai
User-agent: cohere-ai Allow: /
Block cohere-ai at the server or CDN
cohere-ai's robots.txt compliance is unreliable, so a robots.txt rule alone may not stop it. These enforce the block. Matching on the user-agent string still trusts a self-declared header — and no IP-range file exists for this agent, so treat it as best-effort.
if ($http_user_agent ~* "cohere-ai") {
return 403;
}RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} cohere-ai [NC]
RewriteRule .* - [F,L](http.user_agent contains "cohere-ai")
Find cohere-ai in your server logs
grep -i "cohere-ai" /var/log/nginx/access.log | wc -l
Should you block cohere-ai?
Blocking cohere-ai opts your content out of Cohere's model training — a legitimate choice for original content you don't want reproduced by AI. The trade-off: models trained without your content are less likely to know your brand or recommend it unprompted. There is no direct traffic loss today, since training crawlers don't send visitors.

Frequently asked questions
What is cohere-ai?
cohere-ai is Cohere's web crawler for collecting AI training data. Cohere's crawler used for training and grounding its models.
Does cohere-ai respect robots.txt?
Cohere publishes no official crawler documentation, so robots.txt compliance can't be verified; use firewall rules if blocking it matters to you.
How do I block cohere-ai?
Add "User-agent: cohere-ai" followed by "Disallow: /" to your robots.txt file. Because this bot's robots.txt compliance is not reliable, enforce the block with firewall or CDN rules (for example a Cloudflare WAF rule matching the user agent) if it matters to you.
Does blocking cohere-ai hurt my Google rankings?
No. cohere-ai is separate from Googlebot, which handles Google Search indexing. Blocking cohere-ai has no effect on your traditional search rankings.
How can I tell if cohere-ai is crawling my site?
Search your server access logs for the string "cohere-ai" — for example: grep -i "cohere-ai" /var/log/nginx/access.log | wc -l. Our free AI Bot Log Analyzer does this in your browser: paste a log file and it counts hits per AI crawler, including cohere-ai, with per-path breakdowns.
How do I use cohere-ai?
You don't — cohere-ai isn't a tool you run. It's Cohere's own crawler, operated by Cohere, that visits your site from their infrastructure. The only control you have over it is whether you allow or block it, via robots.txt or a server rule. If you're looking to crawl other sites yourself, you'd write your own crawler or use a crawling library; sending "cohere-ai" as your user agent would be impersonating Cohere.
Where is the official Cohere documentation for cohere-ai?
Cohere publishes no official documentation for cohere-ai. That absence is itself worth noting: an undocumented crawler gives you no stated policy to hold it to, and no published IP ranges to verify it against.
