What is GPTBot?
A plain-English definition, and the tools that work with it.
GPTBot is OpenAI's web crawler that collects pages as training data for future models. It is not the bot behind ChatGPT Search results, and blocking it does not remove you from ChatGPT's answers. That is a different bot called OAI-SearchBot.
- Blocking GPTBot is a content-control decision: future OpenAI models learn nothing from your site, so ChatGPT is less likely to describe your brand from memory.
- It does not affect ChatGPT Search, which retrieves through OAI-SearchBot and Bing's index. Many sites block all three OpenAI bots by accident and lose citations they wanted.
- You allow or block it with a robots.txt group naming the exact token: 'User-agent: GPTBot' followed by 'Disallow: /' to block, or 'Allow: /' to permit.
- robots.txt only governs future crawling. It cannot remove your content from a model that has already been trained on it.

GPTBot problems we solve
Hit one of these? Here's the fix.
- I don't know whether to allow or block AI crawlersThere's no universally right answer on training, but there is a wrong one: blocking the search bots by accident while trying to block training.
- ChatGPT and other AI tools can't see my websiteWork through the three causes in order. Access first, rendering second, content last, because fixing content on a page crawlers can't reach changes nothing.
Frequently asked questions
Related terms
- AI crawlerAn AI crawler is an automated bot that fetches web pages on behalf of an AI company, either to train a model, to build a search index that AI answers cite from, or to read a page live when a user asks about it. Each purpose is a separate bot with its own name in robots.txt.
- robots.txtrobots.txt is a plain-text file at a site's root that tells search-engine crawlers which URLs they may or may not crawl. It's used to keep crawlers out of admin, duplicate or low-value areas and to point them at the sitemap, but it controls crawling, not privacy.
- Generative Engine Optimization (GEO)Generative Engine Optimization (GEO) is the practice of making a website usable by AI answer engines like ChatGPT, Claude, Perplexity and Google's AI features, so they can crawl it, read it without JavaScript, and quote it as a source. It overlaps with SEO but optimizes for being cited rather than ranked.
