What Grok actually is
Grok is xAI's assistant. People can use it on the web, in mobile apps, and through X, which gives it a natural connection to live public conversation.
Who uses it in the United States
Pew found that 8% of U.S. adults had used Grok by February 2026. That puts it below ChatGPT and Gemini but slightly above Claude in the same survey.
Who uses it outside the United States
Sensor Tower measured Grok at roughly 3% of the global AI-assistant audience in May 2026. Grok is available through X and standalone apps in many markets, although the July 2026 Grok 4.5 launch did not include the European Union on day one.
What people commonly use it for
People use Grok for current events, questions about online conversation, writing, coding, images, and general help.
What makes Grok different
Its connection to X is the clearest difference. That can make fresh discussion more visible, but it also means the audience and answer can be shaped by a fast-moving social environment.
What this means for your business
Use Grok when recent conversation affects the buying decision. Check the answer against reliable sources before acting, and make sure your own current pages say what changed and when.
A simple next step
- Ask Grok one real question your customer might ask.
- Write down which businesses it names and the reasons it gives.
- Fix the clearest missing or confusing fact on your website.
- Ask the same question again after the change is live.

Conclusion
Grok is worth monitoring when your buyers use it, but one answer is not a permanent ranking. Ask a real buying question, save what Grok says, improve the clearest missing fact or proof point, and ask again.
