Grok is made by xAI and belongs to the Social platforms group of engines we follow. We last reviewed it on 29 October 2026 and plan the next review for 23 November 2026. This page records what we watch, what our own data shows for this engine, and what changed.
What we are watching
Whether xAI publishes a crawler user agent. None is documented today.
Because Grok documents no crawler of its own, the practical control is the access you give to the search systems it relies on.
Crawler access
No dedicated crawler is documented for Grok, so our audit has no bot-level row for it. The table below shows how the other engines in the same group are treated, which is the nearest comparison we can offer.
Others in the Social platforms group
| Engine | Main bot | Blocked by | Share |

Our data
For Grok, as for every engine here: across the 86 readable sites, 15 serve an llms.txt file (17.4%). There is no documented bot to look for in our server log. A single day on a new site is a small sample, and the counts will grow as the log does.
How we review
Grok is reviewed against xAI's own documentation, not against commentary. Each review rereads the pages cited in the guides, notes any change in crawler names, controls or reporting, and edits this page only when something differs. A review that finds no change is still dated, so the date above tells you when the page was last checked.
