What an AI training crawler does

A training crawler gathers public pages that may end up in the data used to train AI models. It sends no visitors back, so blocking it is the usual choice for sites that don't want their content used that way.

Block or allow meta-externalagent in robots.txt

Add one of these to the robots.txt file at the root of your domain. Crawlers read it before they fetch anything else.

Block meta-externalagent

User-agent: meta-externalagent
Disallow: /

Allow meta-externalagent

User-agent: meta-externalagent
Allow: /
