OAI-SearchBot

OAI-SearchBot is a crawler run by OpenAI. It indexes the web for ChatGPT search results.

What it does

OAI-SearchBot crawls pages to build the search index an AI platform answers from. Most operators use a separate user agent for each job, so you can usually allow or block one without affecting the others.

Crawlers that build search indexes used by AI platforms. Access supports discovery but does not guarantee a listing or citation.

User agent

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36; compatible; OAI-SearchBot/1.4; +https://openai.com/searchbot

This is a full user agent string OAI-SearchBot sends. Version numbers change over time; match the OAI-SearchBot token rather than the whole string.

robots.txt

To block OAI-SearchBot, add this to the robots.txt at the root of your site:

User-agent: OAI-SearchBot Disallow: /

Blocking it keeps your pages out of that index, so the platform has less of your content to find and cite. Allowing it makes your pages eligible, not guaranteed, to appear in answers.

To allow it explicitly, for example after a broader rule blocks other crawlers:

User-agent: OAI-SearchBot Allow: /

Check what your robots.txt allows for OAI-SearchBot and the other AI crawlers in this directory.

Verifying requests

OpenAI publishes the IP addresses OAI-SearchBot uses. A request that claims to be OAI-SearchBot from any other address is not genuine.

In SurfacedBy

SurfacedBy's AI traffic tracking recognizes OAI-SearchBot in the user agent and checks each request against OpenAI's published addresses. Only requests that pass count as crawls; the rest are shown separately.
