GPTBot vs OAI-SearchBot vs OAI-AdsBot vs ChatGPT-User
OpenAI documents these tokens for different purposes. A rule for one does not automatically control the others.
GPTBot
Model training. OpenAI's automatic crawler for content that may be used to improve and train generative AI foundation models.
OAI-SearchBot
AI search. OpenAI's automatic search crawler, used to surface and link websites in ChatGPT search results.
ChatGPT-User
User-requested fetch. OpenAI's user-initiated fetcher for certain ChatGPT, Custom GPT, and GPT Action requests.
Common full-site robots.txt block pattern
This example states a crawl preference for the named token. It does not authenticate requests, enforce blocking, or automatically control another token from the same operator.
User-agent: OAI-AdsBot
Disallow: /Check the official operator source before publishing a policy. User-requested fetchers and non-fetcher control tokens can have different behavior from automatic crawlers.
Latest observed pilot policies
These states are calculated from each domain's latest available robots.txt record using the versioned CrawlLedger parser. They are observations of published text, not proof of crawler behavior.

Interpret the state carefully
“Allowed” means a selected group was observed without a blocking rule for the tested policy shape. “Partial” means at least one non-empty disallow path was observed. “No matching group” is silence, not an affirmative grant. None of these states authenticate the requester or establish legal permission.
