Understand AI search, user-requested retrieval, and model-training access on your changelog.
Manage access for AI search, user-requested retrieval, and model-training crawlers. These uses are different: appearing in an AI search answer does not require allowing model training.
Google Search's AI features use Googlebot and normal search indexing controls. User-requested fetchers may not honor robots.txt in the same way as automatic crawlers.
The current AI Crawler Access setting covers supported search, retrieval, and training agents together. It is separate from the Search Engine Indexing setting.
These rules include the current OpenAI, Perplexity, and Anthropic agent names, alongside legacy and other supported agents. Access does not guarantee indexing, citations, or recommendations.
A free changelog on its verified, active custom domain is automatically eligible for search indexing when it is public and has no password. On that hostname, ChangeCrab explicitly allows OAI-SearchBot, PerplexityBot, Claude-SearchBot, ChatGPT-User, Perplexity-User, and Claude-User.
This automatic policy keeps GPTBot, ClaudeBot, Google-Extended, and the other supported agents outside that search and retrieval group restricted. It does not open model-training access, even if an older saved AI mode was Allow or Optimize.
The exception applies only to the active custom hostname. Free ChangeCrab-hosted copies and unverified custom domains remain excluded from indexing and do not receive this exception. Crawler settings remain a paid feature.
Robots.txt expresses crawler preferences; it is not access control and cannot guarantee that every agent respects your rules. Private and password-protected changelogs remain protected regardless of AI settings or custom-domain status. Use those features for content that should not be public.
Visit /robots.txt on the hostname you want to check. For each supported agent,
Allow: / permits crawling and Disallow: / requests exclusion.
Search indexing also depends on the page's robots meta tag. Check server logs to confirm
that permitted crawlers can retrieve your public pages; crawler traffic alone does not prove AI citations.
