Quick answer

Grok is the AI assistant and model family made by xAI. You can chat with it at grok.com, in the Grok mobile apps or inside X. Like ChatGPT, it writes, answers questions, reads images and searches the web, and it can also draw on public posts on X.

## Why it matters for a small business

Grok's distinctive strength is recent information: because it is built into X, it can pull in what people are posting about a topic right now. That helps with spotting trends or reactions, and it is also the risk, since social posts are often wrong or one-sided. As of October 2026, xAI lists **Grok 4.7** as its newest flagship model, and the SuperGrok plan at $30 a month for heavier personal use.

Who it suits: marketers and owners who want a quick read on public conversation, and people who already spend time on X. It is a less natural fit for writing inside Microsoft 365 or Google Workspace, where Copilot and Gemini are built in. For work content, turn off **Improve the Model** in Grok's data settings or use Private Chat, which xAI says is not used for training.

## In a real lesson: Get Your Business Recommended by ChatGPT

Stepthrough has no Grok lesson. The habit from [Get Your Business Recommended by ChatGPT](https://learn.ynteractive.com/content/get-recommended-by-chatgpt) applies directly: when an assistant answers from the web, open **Sources** and see what it relied on before you trust it.

In that lesson the answer leaned on firm websites, a Chamber directory and a local "best of" list. With Grok, the sources may be posts on X. Check who wrote them before you repeat a claim.

## Common confusions

### Grok vs xAI

Grok is the assistant and the models. [xAI](https://learn.ynteractive.com/content/glossary/xai) is the company that makes them.

### Grok vs ChatGPT

Both are general assistants. Grok leans on real-time posts from X; [ChatGPT](https://learn.ynteractive.com/content/glossary/chatgpt) has more office features such as projects and connectors to work files.

## Tips

- Treat claims drawn from social posts as leads to verify, not facts.
- Use Private Chat for anything you don't want kept for training.
- Give Grok the same four-part prompt you use elsewhere, so you can compare answers fairly.
