These two tools are not really measuring the same thing, which makes them worth running together rather than choosing between them.
What PromptRush checks
PromptRush focuses specifically on third party mention signals, whether a business is already being talked about across review sites, listicles, and forums like Reddit, the exact kinds of sources AI models already lean on heavily when generating an answer. It is measuring earned visibility that exists outside your own website entirely.
What ours checks
Ours looks inward, at the site itself, whether AI crawlers can actually access and correctly parse it, robots.txt rules, an llms.txt file, schema, content structure. That is a completely different question from whether anyone else is talking about the business.
Why both matter
A site can be technically perfect and still get skipped if nobody else is citing it anywhere. A business can have glowing third party mentions everywhere and still lose the citation if the AI crawler cannot actually read the site when it goes to verify. Real AEO work touches both. PromptRush answers the earned mention question, ours answers the technical access question, and a serious visibility effort needs an honest read on both.
