Is GPTBot blocked from your site?
GPTBot is OpenAI's training crawler. If your robots.txt allows it, your articles can end up training ChatGPT. Check whether your site is exposed in two minutes.
GPTBot is the User-agent token OpenAI uses for the crawler that gathers public content for model training. It is not the same as ChatGPT-User (which fetches on demand when a person asks ChatGPT to look something up) or OAI-SearchBot (which powers ChatGPT's search results). The three use different tokens and behave differently, so a robots.txt rule that mentions only one will leak traffic to the others.
Most sites do not have a GPTBot rule at all. If yours is silent, GPTBot is allowed by default, and OpenAI will continue to crawl whatever pages it can reach. You can confirm the current state in seconds by pasting your homepage URL above. The auditor reads your robots.txt against 33+ named AI bots and tells you which ones are permitted, denied, or unaddressed.
Frequently asked questions
- What is GPTBot? +
- GPTBot is OpenAI's web crawler. It fetches public pages so OpenAI can train future versions of ChatGPT and related models on the content it collects.
- How do I block GPTBot? +
- Add a User-agent: GPTBot rule with Disallow: / to your robots.txt. The change takes effect on the next crawl, usually within a few days for active domains.
- Will blocking GPTBot affect my Google ranking? +
- No. GPTBot is OpenAI's training crawler, not a search-engine indexer. Googlebot and Google-Extended are separate tokens that work independently of GPTBot.
- Does Hyperguard block GPTBot for me? +
