Grok Prompts: Copy and Paste Prompts for X Posts and Research

Most Grok prompt lists I see online are really ChatGPT prompts with the name swapped. That misses the point. What makes Grok different is that it can search X and the wider web live, and show you where its answer came from. So the best prompts lean on that: what are people saying right now, what's the mood around this topic, who's talking about it, and what did they link to.

Below are a dozen original prompts I'd hand to a business owner, grouped by the job they do. Each has one line on when to use it. Swap the [brackets] for your own details, paste the prompt into Grok and see what comes back.

Which Grok prompts work for trend research on X?

This is Grok's home ground. xAI says Grok searches the web and X in real time and gives live citations, so use it before you write anything that depends on what people are talking about this week.

When to use it: before you plan a week of posts, or when a customer asks what's going on in your industry and you want a quick, sourced answer.

Copy this prompt

Search X and the web for what people in [your industry] are talking about right now.
Give me the five topics getting the most conversation, a one-sentence summary of each, and the main viewpoints on each side.
Cite your sources so I can check them. Tell me which topics are fading and which are still building.

When to use it: when a competitor or a news story could affect your customers and you want to see the reaction before you respond.

Copy this prompt

Look at the recent conversation on X about [competitor, brand or news story].
Summarise the main complaints and the main praise in plain English, with a few example posts for each.
Then tell me one opening this gives a small business like mine, which is [what you sell] for [who you sell to].

When to use it: when you're choosing which questions to answer in your own content.

Copy this prompt

What questions are people asking on X and across the web about [your topic]?
List the ten most common, group them by theme, and mark which ones nobody seems to be answering well.

How do I write X posts and replies in my own voice with Grok?

Grok writes a decent post on the first go, but it sounds like everyone else's unless you show it how you write. Paste in two or three of your own posts, then ask for new ones. Grok also has custom instructions, so once you've got a voice description you like, you can save it there rather than pasting it every time.

When to use it: when you know what you want to say but the words won't come.

Copy this prompt

Here are three posts I've written that sound like me: [paste three posts].
Describe my voice in four short bullet points: sentence length, tone, words I lean on and things I never do.
Then write five new posts for X about [topic]. Keep each short enough to post as it stands and open with something that earns the next line.

When to use it: when someone posts a question or complaint about your area and you want to reply quickly without sounding like a robot.

Copy this prompt

Someone has posted this on X: [paste their post].
Write three possible replies from me. I'm [your role] at [your business]. One should be warm and helpful, one short and witty, and one that answers the question and invites them to message me.
Don't be defensive, don't sell, and don't use hashtags.

When to use it: when a post has done well and you want to build on it rather than start again.

Copy this prompt

This post of mine got a strong response: [paste it].
Tell me why you think it worked in two or three sentences. Then write a follow-up thread of four posts that goes deeper and ends with a question for my audience.

Can Grok summarise a live conversation with sources?

Yes, and this is the job I'd point most business owners to first. Because Grok can see live X and web content and cite it, you can ask it to boil down a long thread or a fast-moving story and then click through to check. Always do that last step. A summary with sources is only useful if you look at one or two of them.

When to use it: when a topic is moving fast and you need to be across it in a few minutes.

Copy this prompt

Summarise the current conversation on X and the web about [topic or event].
Structure it as: what happened, who's saying what, what's still unclear, and what might matter to a business like mine.
Add a citation after every claim. If you can't find a source for something, say so rather than guessing.

When to use it: when you're about to comment publicly and want to be sure you've read the room.

Copy this prompt

I'm thinking of posting about [topic]. Before I do, find out how people have reacted to similar posts or announcements recently.
Tell me what landed well, what drew pushback and anything I should avoid saying. Cite the examples.

What are good prompts for Grok Imagine?

xAI describes Imagine as text-to-image and text-to-video in one thread, so you can ask for a picture, then ask for it to move. For a small business that means quick visual ideas for posts, not a finished brand identity. Describe the scene, the mood and where it will be used.

When to use it: when you need a visual idea for a post and don't have a photo to hand.

Copy this prompt

Create an image for an X post about [topic]. The scene: [describe what's happening]. The mood: [warm, bold, calm or playful].
Keep it simple, with one clear subject and space at the top for a line of text. No logos or readable words in the image itself.

When to use it: when you want a short moving clip from an image you've already made.

Copy this prompt

Take the image above and turn it into a short video. Add gentle movement: [what should move, such as steam rising, leaves blowing or a slow camera push in].
Keep the mood [calm or lively] and make it suitable for a social feed.

One caution from me. Images and clips that show your real products, premises or team will always beat generated ones for trust, so use Imagine for ideas and backgrounds, not to stand in for what you sell.

How do I use Grok to analyse a PDF or a file?

xAI lists file and PDF analysis among Grok's features, which makes it handy for the long documents nobody wants to read at the end of a day. Upload the file, then ask a specific question. Vague requests get vague summaries.

When to use it: when a supplier contract, report or proposal lands in your inbox and you need the key points first.

Copy this prompt

I've uploaded a document: [name or type of document].
Give me a summary in plain English for a busy business owner: what it says, the three most important points, anything unusual or one-sided, and questions I should ask before I agree to anything.
Quote the exact wording for anything you flag so I can find it myself.

A word of common sense: don't upload files that hold client details or anything you'd be uncomfortable seeing elsewhere. Strip the names out first, or keep that work for a tool and plan you've checked carefully.

What tools work well alongside Grok?

Grok does the research and first draft; the rest of your stack does the doing. Most people I work with pair it with a scheduler such as Buffer or Hootsuite for posting, a notes app such as Notion or Google Docs to keep the prompts and best outputs, and Canva for turning an Imagine idea into a finished graphic. Nothing needs connecting. Copying across by hand is fine.

If you'd like to understand how to switch the Grok button on X off when you don't want it, I've covered that in my guide to turning the Grok button off. And if your main platform is LinkedIn rather than X, these prompts for LinkedIn posts are written for how that audience reads.

If you'd like help building prompts like these around your own business, so the output sounds like you from day one, this is how I work with business owners.
