cohere-ai is Cohere's crawler that collects web content that may be used to train AI models.
What a visit means
A visit means your content is being collected, possibly for training. Nobody asked about you; training crawlers read the web in bulk and don't link back.
Training crawls say nothing about what people ask right now. SenseGap keeps them apart from visits made while answering a person, so a crawl spike never looks like demand.
Detection, the header SenseGap matches.
How SenseGap recognizes cohere-ai. By its User-Agent header. A separate check then decides whether the visit is real.
Every request carries a User-Agent header naming the software that sent it. SenseGap counts a request as cohere-ai when that header contains any of cohere-ai or cohere-training-data-crawler, in any letter case. The header is plain text, so any script can copy it. Matching the name is where recognition starts, not where trust starts.
/cohere-ai|cohere-training-data-crawler/iVerification, how to tell a real visit from a fake.
cohere-ai can't be fully verified. SenseGap knows of no published IP ranges or DNS names for it, so the name is all there is.
How we verify botsNot beyond the user agent. SenseGap knows of no published IP ranges or DNS names for cohere-ai, so anyone can send its name. SenseGap marks these visits Unverified rather than calling them real.
robots.txt, rules you can copy.
Block or allow cohere-ai in robots.txt. Its robots.txt name is cohere-ai. Paste a group into the robots.txt at your site's root.
User-agent: cohere-ai
Disallow: /User-agent: cohere-ai
Allow: /User-agent: cohere-ai
Disallow: /private/One rule catches people out. Under the robots.txt standard (RFC 9309), a crawler that finds a group naming it follows only that group and ignores your User-agent: * rules. If you add a cohere-ai group, repeat in it anything from the catch-all group you still want applied.
robots.txt is a request, not a lock. To enforce a block, match the User-Agent header at your server or CDN. In nginx:
# nginx, inside a server block
if ($http_user_agent ~* "cohere-ai|cohere-training-data-crawler") {
return 403;
}SenseGap reads your robots.txt and shows, bot by bot, what you allow and which bots fetched pages you disallowed. See what you get.
Trade-off, what blocking changes.
Should you block cohere-ai? It depends on what you want from Cohere. Here is what each choice means.
If you allow it
Future models may learn from your content, so they know your products, prices and wording.
If you block it
New content stops reaching that company's training data. It doesn't remove what was already collected, and because training crawlers don't send visitors, it costs no clicks directly.
