How to use ChatGPT to write LinkedIn posts that sound like you

To get ChatGPT to write LinkedIn posts that sound like you and actually get read, give it three things before you ask for a post: your own best posts, a few notes on how you talk, and real examples of what's working in your space right now. Then ask for one post at a time, built on one real story of yours, and do the last edit yourself.

That's the whole method, and the rest of this is the detail, plus eight prompts you can copy straight into ChatGPT or Claude.

Why a blank ChatGPT sounds like everyone else

When you open a fresh chat and type "write me a LinkedIn post about leadership", ChatGPT has nothing to go on but the topic, so it writes the average of every leadership post it's ever read. That's why you get the neat little lines, the list of lessons and the question at the end asking what everyone thinks. Your readers have seen that post a thousand times, so they scroll right past it.

The model is fine. It just hasn't been told anything about you, your buyers or what they care about this month, so it guesses, and a guess always comes out bland. We wrote more about why generic AI content doesn't work if you want the longer version.

Feed it three things first

Before you ask for a single post, set ChatGPT up with material only you have. You can put it all in one long first message, or save it in a project or in your custom instructions so you don't have to paste it every time.

First, your own posts. Paste in five to ten of your best ones, the ones people actually replied to. Showing it how you write works far better than describing it, because most of us can't describe our own voice but we can point at it.

Second, a few notes on how you talk. Do you write short lines or long ones, do you swear, do you tell stories or make points, and what words would you never use? A short list here saves you a lot of editing later.

Third, what's working in your space right now. This is the one most people skip, and it's the one that matters most. Find a handful of recent posts from people a step or two ahead of you that did much better than their usual, and paste them in. We show you how to find them in how to research your competitors on LinkedIn.

Eight prompts you can copy

Use these in order the first time, and after that just pick the ones you need. Swap the parts in brackets for your own details.

1. "Here are eight of my LinkedIn posts. Read them and describe how I write: my sentence length, the words I use a lot, how I open and how I end. Don't praise it, just describe it so you can copy it."

2. "From now on, write in the style you just described. Don't use words I didn't use in those posts, don't end with a question to the reader, and don't add a summary at the end."

3. "Here are five recent posts from people in my space that did much better than their usual. What do they have in common? Look at the topic, the first line, the length and the shape, and ignore the exact words."

4. "Based on what's working in those posts, and knowing my audience is [who you help], give me ten post ideas I could write this week. For each one, tell me which of my own stories or opinions it would need."

5. "Here's something real that happened to me: [the story in a few plain lines]. Write it as a LinkedIn post in my style, using the shape that's working in my space. Keep it under two hundred words."

6. "Give me five different first lines for this post. Make each one specific enough that only someone in my niche would stop for it." There's more on openers in how to write a LinkedIn hook.

7. "Read this draft and mark every sentence that sounds like it could have come from anyone. Suggest a plainer version of each one that sounds like me."

8. "Here's how my last five posts did: [paste the numbers]. What did the best one do that the others didn't, and what should I try next week?"

Every one of these works the same way in Claude. Paste the same prompts, and if you keep your posts and voice notes in a Claude project, every new chat starts already knowing how you write.

One post, one story, one chat

The fastest way to get bland output is to ask for a month of posts in one go. The quality drops after the first few, because it runs out of real material and starts filling the gaps with filler.

So ask for one post at a time, and give it one real thing to work from each time, like something a client said, a mistake you made or a number from your own work. The story is yours and the shape comes from what's working, and that mix is what makes a post sound like you and still get read.

Then do the last pass yourself. Read it out loud, cut the line at the end that sums everything up, and add one detail only you would know. It takes a few minutes, and it's the part that makes AI writing sound like you instead of like a template.

What changes when ChatGPT can see your real data

The weak spot in all of this is the third thing you feed it. Finding posts that beat their own usual, copying them in and pasting your own numbers takes time, and the list goes stale in a week or two. Most people do it once, feel good about it and never do it again, so ChatGPT slides back to guessing.

When you connect ChatGPT or Claude to your real data, that chore goes away. You can ask "what's working for the people ahead of me this week?" and it answers from real posts and real numbers, then writes your version from that. You can ask how your last post did next to theirs, and it can tell you without you pasting a thing.

That's what Kadenza does. It shows you which posts from the people ahead of you on LinkedIn, Instagram and YouTube beat their own usual, keeps your own numbers next to theirs, and connects to the AI you already use, so the prompts above run on real, current material every time you use them.

Where to start this week

Pick your eight best posts tonight and run the first two prompts. Tomorrow, find five posts in your space that beat their author's usual and run prompts three and four. By the end of the week you'll have one post that sounds like you and starts from something that's already working, which is more than a blank chat has ever given you.

If you're weighing up writing apps, there's a fair look at them in Kadenza compared with an AI writing tool. And if you'd like ChatGPT or Claude to have the finding part done for you, the plans are in the pricing section.
