Definition
OAI-SearchBot is OpenAI's crawler for surfacing websites in ChatGPT search, and blocking it keeps your pages out of ChatGPT search answers.
OAI-SearchBot explained
OpenAI's documentation describes OAI-SearchBot as the bot used to surface websites in search results in ChatGPT's search features. It is separate from GPTBot, which collects training data, and from ChatGPT-User, which visits pages when a user's request calls for it.
OAI-SearchBot follows robots.txt. OpenAI says sites that opt out of OAI-SearchBot will not be shown in ChatGPT search answers, though they can still appear as navigational links. It also notes that it can take about 24 hours for its systems to adjust after you update robots.txt.
For most brands that want AI visibility, OAI-SearchBot is the most important OpenAI bot to allow. Check more than robots.txt: firewalls, rate limits and bot-protection services at your CDN can block it silently even when robots.txt allows everything. Server logs or a crawler access check will show whether it is receiving normal responses.
Example
Someone asks ChatGPT “which accounting software integrates with Shopify” and ChatGPT searches the web. Because OAI-SearchBot has crawled your integration page, ChatGPT can cite it in the answer. If your robots.txt blocked OAI-SearchBot, that page wouldn't be a candidate.
Why it matters
It is the gatekeeper for ChatGPT search citations. If it can't fetch your pages, your content can't be quoted in ChatGPT's search answers.
