ChatGPT-User is OpenAI's on-demand AI fetcher. Fetches your page live when a ChatGPT user asks about you in a conversation. ## What does ChatGPT-User do with your content? Fetches your page live when a ChatGPT user asks about you in a conversation. Like most AI crawlers, ChatGPT-User reads your pages as plain HTML — it does not run JavaScript — so content that only appears after scripts execute is invisible to it. ## Should you block ChatGPT-User? Blocking ChatGPT-User makes your business invisible to OpenAI's AI when customers ask it for recommendations. If you want to be found, allow it; block it only if you have a specific reason to keep OpenAI's AI away from your content. ## How do you allow or block ChatGPT-User in robots.txt? Add one of these snippets to the robots.txt file at the root of your site. The first explicitly allows ChatGPT-User everywhere; the second blocks it completely. ``` # Allow ChatGPT-User User-agent: ChatGPT-User Allow: / # Block ChatGPT-User User-agent: ChatGPT-User Disallow: / ``` ## Is robots.txt enough? Not always. CDNs and firewalls (Cloudflare in particular) can block crawlers at the network level regardless of what robots.txt says — Cloudflare blocks AI crawlers by default for many accounts. If you want ChatGPT-User to reach your site, check your CDN's bot settings too. SeeGeo's free audit checks both. ## How do I check whether ChatGPT-User can read my site right now? Two checks, both needed: read your robots.txt for a group naming ChatGPT-User (or the * group it falls back to), then request your homepage with ChatGPT-User's user agent and confirm you get a 200 with your real HTML rather than a 403 or a challenge page. SeeGeo's free crawler check runs both in a few seconds. [Run the free AI crawler check](https://see-geo.com/ai-crawler-check) ## How does ChatGPT-User compare to similar crawlers?

The numbers Crawler access is where AI visibility starts or ends: a blocked crawler can't read you, and an AI that can't read you can't recommend you. - Visitors arriving from AI assistants convert at roughly 4.4x the rate of traditional organic search on average (Semrush, cross-industry, 2026). - AI-assistant referrals are still only about 1% of total web traffic — small, but the fastest-growing acquisition channel measured (multiple 2026 studies). - Adobe Digital Insights (Q1 2026) measured AI-assistant visitors converting 42% better than non-AI traffic — a full reversal from the year before. - Cloudflare blocks AI crawlers by default for many accounts, so sites are often invisible to AI without anyone having decided to be. - Content edits alone — statistics, citations, quotable structure — can raise AI visibility on the order of 30–40% (Princeton GEO study, KDD 2024). ## Frequently asked questions ### What is ChatGPT-User? ChatGPT-User is OpenAI's on-demand AI fetcher. Fetches your page live when a ChatGPT user asks about you in a conversation. ### Should I block ChatGPT-User? Blocking ChatGPT-User makes your business invisible to OpenAI's AI when customers ask it for recommendations. If you want to be found, allow it; block it only if you have a specific reason to keep OpenAI's AI away from your content.. ### Does ChatGPT-User run JavaScript? No. ChatGPT-User, like most AI crawlers, reads raw HTML without executing JavaScript. If your content only renders client-side, it is effectively invisible to it. ### Can ChatGPT-User read my website? Only if two things are true: your robots.txt does not disallow ChatGPT-User, and your server or CDN actually serves the page when ChatGPT-User asks. Firewalls can block it regardless of robots.txt, so the reliable way to know is to fetch your homepage as ChatGPT-User — the free check on see-geo.com/ai-crawler-check does exactly that. ## Related pages - [What is GPTBot?](https://see-geo.com/bots/gptbot) - [What is OAI-SearchBot?](https://see-geo.com/bots/oai-searchbot) - [What is Claude-User?](https://see-geo.com/bots/claude-user)
