How to Use Grok: A Simple Guide for Business Owners

If you run a small business, you've probably noticed Grok popping up in X and wondered whether it's worth your time. I think it can be, for a narrow set of jobs. It isn't the tool I'd pick for everything, but it does a few things differently from the other assistants, and those are worth knowing about before you decide.

This guide covers where to find Grok, what it's good for, the settings to look at on day one, a simple routine to try, and the common-sense rules I'd keep about what you paste in. Everything about the product comes from xAI's own description of Grok (xAI is the company that makes it).

What is Grok?

Grok is an AI assistant you can chat with, and it's closely tied to X. You chat to it in the same way as any other assistant: type or speak a question, and it writes back. xAI describes it as being able to search the web and X live, with citations, so its answers can include what happened this morning rather than only what it already knew.

How do you use Grok on X, the web and your phone?

There are a few ways in, and they all lead to the same assistant:

• On the web. Grok has its own website, so you can use it from a browser without needing X open.
• On iOS and Android. There are apps for both, which is handy for voice conversations on the move.
• Inside X. Grok also appears within X itself, so you can ask about a post or a trend without leaving the timeline.

You sign in with your X account or with an email address. xAI says Grok is free to try, with an upgrade called SuperGrok for higher limits, priority access and multi-agent. Start on the free version and see whether you'd miss anything before you think about upgrading.

What is Grok good for in a small business?

Here's where I'd use it, based on what xAI lists as its features:

• Live research with sources. Because it searches X and the web in real time and gives citations, it's good at "what are people saying about this today?"
• Spotting trends. xAI highlights its real-time X integration for breaking news and trends, which suits anyone who posts regularly.
• Reading long files. It can analyse files and PDFs, so a long report or proposal becomes a short summary with questions to ask.
• Voice conversations. Talking an idea through while you walk or drive, then asking it to tidy the result.
• Pictures and short clips. Imagine makes text-to-image and text-to-video in one thread, handy for post ideas.
• Writing help. It has a Canvas for drafting and editing longer pieces of writing.

Where it's less obviously the right pick is quiet, private work: a long document that needs careful editing, or a task that has nothing to do with current events. Plenty of the other assistants are just as capable there. I'd treat Grok as the one you reach for when the answer lives on X or in this morning's news.

How do I set Grok up to sound like me?

xAI lists custom instructions among Grok's features, and that's the first setting I'd look at. Custom instructions are standing notes that Grok reads before every chat, so you don't have to repeat yourself. It also lists memory across chats, which means it can carry useful details from one conversation to the next.

Use your instructions for who you are, who you serve, how you like to write and what you never want to see. Keep them short and plain. Here's a starting point.

Copy this prompt

I run [type of business] for [who you serve]. I write in a [warm, direct, light-hearted] voice, in short sentences, using UK spelling.
Never use jargon, hashtags or exclamation marks. When I ask for research, give sources I can check. When I ask for a post, give me three options.
Ask me one question if you need more information before you start.

What's a simple first-day routine for Grok?

Don't try to learn everything at once. This is the routine I'd give a business owner for the first day:

1. Sign in with your X account or email and open the website or app.
2. Add your custom instructions, using the starter above.
3. Run one research question about your industry and click through to two of the sources it cites.
4. Write one post or reply by pasting in a couple of your own and asking it to match them.
5. Try Imagine once to see whether the visuals suit you.
6. Save what worked. Keep the prompts you liked in a document you can reuse.

That's about half an hour, and by the end you'll know whether Grok earns a regular slot in your week. If it does, make it a habit rather than an experiment: a few minutes each morning to check what's being said in your area, one post drafted from it, and one reply to someone worth answering. Small and regular beats a big burst once a month.

It also helps to decide in advance what you want from it. I'd suggest picking one job, such as research before you post, and getting good at that before you add another. Business owners who try to use an assistant for everything on day one usually end up using it for nothing by the end of the week.

What are good first prompts to try with Grok?

Two to start with. The first one is for research; the second is for turning that research into something you can post.

Copy this prompt

Search X and the web for what's being said about [topic in your industry] in the last few days.
Give me a short summary, the main points of disagreement and links to your sources. Then suggest three angles I could post about as [your role].

Copy this prompt

Turn the angle I like best into an X post of one to three short sentences, written the way I write.
Here are two examples of my own posts for style: [paste two posts]. Then write a short reply I could use if someone disagrees.

If you'd like more to copy, I've written a full set of Grok prompts for X posts and research grouped by job.

One more habit worth building is keeping a running document of your best prompts and the outputs you were pleased with. When a prompt works, paste it in with a note on what it was for. In a month you'll have a small library that's tailored to your business, and that's worth far more than any list I could give you.

Is it safe to use Grok for business?

The same common sense applies as with any AI assistant. Treat what you type as something that could be seen by someone other than you, and keep client details out of it. If you wouldn't put it in an email to a stranger, don't paste it into a chat. Take out names, contact details and anything covered by a confidentiality agreement, and check the settings in your account for what's shared and saved.

The other half of safety is checking. Grok gives citations, which is a real advantage, but a citation only helps if you click it. Read at least one source before you repeat a claim publicly.

Which tools can I use alongside Grok?

Grok is the research and drafting step. For the rest, a scheduler such as Buffer or Later for posting, a notes app such as Notion or Apple Notes for your saved prompts and Canva for finishing visuals cover most of what a small business needs. If you'd rather not see Grok in your timeline at all, here's how to turn the Grok button off.

If you'd like someone to look at where AI would help your business most, and set it up with you, this is how I work with business owners.
