ChatGPT Agent is a bot operated by OpenAI that browses the web on its own to finish multi-step tasks. ChatGPT Agent is an AI agent created by OpenAI that can use a web browser. It honours robots.txt, and a request claiming to be ChatGPT Agent can be checked against a published IP range file.

robots.txt

Allow or block ChatGPT Agent

Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.

Block ChatGPT Agent
User-agent: ChatGPT Agent
Disallow: /

Blocks every path for this crawler only.

Allow ChatGPT Agent
User-agent: ChatGPT Agent
Allow: /

Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.

Allow, except the pages you never want quoted
User-agent: ChatGPT Agent
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /search

Edit the Disallow paths to match your own account, checkout and search URLs.

What blocking actually costs you

Blocking ChatGPT Agent stops automated sessions that fill forms, click through flows and read pages the way a logged-in user would. Rate limits and challenges usually work better here than a robots.txt line.

Is that really ChatGPT Agent?

A user-agent header is a string the client chooses. Scrapers copy ChatGPT Agent precisely because site owners allow it. OpenAI publishes one range file per bot. Use the file listed against this agent in the bots documentation, not the GPTBot file.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
