ChatGPT-User

What does ChatGPT-User do?

ChatGPT-User is a user agent OpenAI uses for certain user‑initiated actions in ChatGPT and Custom GPTs. When a user asks a question, the agent may fetch a web page in real time to provide up‑to‑date information. It does not crawl automatically and is not used for search indexing; those roles belong to OAI-SearchBot and GPTBot. Because the requests are triggered by a user, robots.txt rules may not apply.

Should I allow and optimize for ChatGPT-User to drive organic growth?

ChatGPT-User powers user‑initiated browsing, shopping research and agentic actions that can recommend products and provide direct links to merchants, driving referral traffic automatically tagged with utm_source=chatgpt.com. Its integration with Shopping Research and the upcoming Instant Checkout lets users move from discovery to purchase within the chat experience, while the new agent mode and Apps enable booking and form‑fill tasks. Marketers should ensure their sites are crawlable by OAI-SearchBot to appear in ChatGPT Search, provide clear structured product data, and allowlist ChatGPT-User/agent traffic so that referrals and conversions are captured.

Data Usage & Training

ChatGPT-User does not collect data for AI model training. OpenAI uses GPTBot for that purpose. Blocking ChatGPT-User only stops user-initiated browsing in ChatGPT conversations.

How ChatGPT-User Accesses Content

Here's how ChatGPT-User accesses your site and understands your content:

• HTML content via direct HTTP requests
• Can process JavaScript-rendered content
• Follows redirects
• Respects robots.txt directives
• User-initiated, not automated crawling

On-demand only. Fetches pages when ChatGPT users explicitly request browsing during their conversations.

How to Block or Control ChatGPT-User

Because ChatGPT-User requests are user-initiated, robots.txt rules may not apply. To block it, use server-side UA string matching or IP-based blocking with the published IP ranges at https://openai.com/chatgpt-user.json. For search visibility control, manage OAI-SearchBot separately in your robots.txt.

Common Issues & Troubleshooting

Watch out for these common problems when working with ChatGPT-User:

• Login walls completely block access
• Some CDN/WAF services block ChatGPT-User by default
• Heavy client-side rendering may limit content visibility
• Aggressive rate limiting
• CAPTCHA and bot detection systems
