# What is ChatGPT agent?

The cloud browser behind ChatGPT agent and ChatGPT Work, which opens sites and acts for a user. It has no robots.txt token and signs its requests with Web Bot Auth as Signature-Agent: "https://chatgpt.com".

- **robots.txt token**: No token
- **Operator**: OpenAI
- **Purpose**: Agents
- **Obeys robots.txt**: The operator does not say.
- **Documented by operator**: Yes, on the operator's own pages.
- **Signature key directory**: [chatgpt.com/.well-known/http-message-signatures-directory](https://chatgpt.com/.well-known/http-message-signatures-directory)
- **Documentation**: [help.openai.com](https://help.openai.com/en/articles/11845367-chatgpt-agent-allowlisting)

Cloudflare labels this traffic chatgpt-agent. Dots appears to run in the same browser, but that is inferred from the Dots docs, not stated by OpenAI.

ChatGPT agent has no robots.txt token, so no User-agent rule can target it. Where the operator signs requests with Web Bot Auth, verify the signature and allow or block it at your server or CDN.
