The short answer
We can’t yet give a reliable answer for wikipedia.org — ChatGPT cites it on too few queries in our index so far (or hasn’t cited it yet). We only publish what we’ve actually measured, so this page will fill in as coverage grows. You can check it directly now: the free Domain Check reads the same index live and returns the real queries any domain is cited on.
Why no answer yet?
Our index grows continuously, but we won’t state that a brand is — or isn’t — recommended until we have enough recorded answers to be fair. Run a Domain Check for wikipedia.org to see its current standing directly.
