How to Use ChatGPT to Write LinkedIn Posts (Without Sounding Like a Robot)
Bas Smeets7 min read
Use ChatGPT for LinkedIn posts by giving it a specific real-world input, a clear tone instruction, and a format constraint. Then edit the output until it sounds like you. That editing step is what separates posts that get ignored from posts that get replies.
The coaches who complain that ChatGPT makes their posts sound generic are usually skipping the editing step or giving it prompts that are too vague. "Write a LinkedIn post about productivity for coaches" will produce something flat. "I had a client this week who kept cancelling sessions and I realized it was avoidance, not schedule conflicts, write a LinkedIn post about that" will produce something worth editing into a real post.
This is the actual workflow, not the theory.
Step 1: Start with something real
The biggest mistake coaches make with AI-generated content is starting with a topic instead of a moment. Topics produce generic content. Moments produce specific content.
Before you open ChatGPT, write two or three sentences about something real:
An observation from a session this week
A question a client asked that made you think
Something you used to believe about coaching that you've changed your mind on
A pattern you keep seeing across clients
That's your starting material. The AI's job is to turn it into a post draft. Your job is to give it something true to work with.
Session observations are the most reliable source of LinkedIn content for coaches.
Step 2: Write a specific prompt
Here's the prompt structure that consistently produces usable output:
"Here's a coaching observation: [your 2-3 sentences]. Write a LinkedIn post in a direct, conversational tone. No bullet points. Under 200 words. Start with a statement, not a question. Make one clear point."
Breaking that down:
The observation: the actual content, in your words
Tone instruction: direct, conversational. Not "professional" (ChatGPT's default "professional" is often corporate and flat)
Format constraint: no bullet points, word count. These prevent the AI from defaulting to list format, which is its safety behavior when uncertain
Hook instruction: "start with a statement, not a question" prevents the generic "Have you ever noticed..." opener
Prompt in practice
"Here's a coaching observation: I've noticed that when clients say they want more clarity, what they usually mean is they want permission. They already know what they want to do. They're waiting for someone to tell them it's okay. Write a LinkedIn post in a direct, conversational tone. No bullet points. Under 180 words. Start with a statement."
Step 3: Evaluate the output honestly
ChatGPT will produce a draft. Read it as if you didn't write it. Ask:
Does the first line make me want to keep reading?
Does it say something specific or is it generic advice that could apply to anyone?
Does it sound like me or does it sound like a content team?
Is there one clear point or is it trying to say three things?
Most first drafts need the opener rewritten and the ending cut or changed. The middle is often usable. That's normal. You're not looking for a perfect draft. You're looking for something to react to and edit.
Step 4: Edit until it sounds like you
This is the step most coaches underinvest in. They take the draft, make minor tweaks, and post it. Then they wonder why it doesn't get engagement.
Edit more aggressively than feels comfortable. Specifically:
Rewrite the hook
ChatGPT hooks tend to be either too clever or too broad. Replace it with the most direct version of your main point. The hook is the most important sentence in any LinkedIn post. Write it yourself, even if everything else comes from the AI draft.
Add one specific detail
The AI draft will be general. Add one concrete detail: a client observation (anonymized), a specific number, a particular situation. One specific detail changes the entire tone from "generic advice" to "this person has actually seen this play out."
Cut the filler closing
AI-generated posts almost always end with a call-to-action or summary that's too neat. "What do you think? Share your thoughts below." Cut it or replace it with something direct: a single question you actually want answered, or just let the post end on the main point.
Read it aloud
If it doesn't sound like something you'd actually say out loud to a colleague, keep editing. The spoken test is more reliable than reading it on screen.
The tell for AI content
If every sentence is roughly the same length and the post flows too smoothly from point to point, it's usually AI-heavy. Real writing has rhythm variation: short sentences, then longer ones, then short again. Break the pattern on purpose.
Prompts for common coaching post types
The observation post
"Here's something I keep seeing in coaching sessions: [observation]. Write a LinkedIn post in a direct tone, under 200 words, that makes coaches think about this pattern in their own clients. No bullet points."
The contrarian take
"Here's a common piece of advice about [topic] that I think is wrong or incomplete: [your view]. Write a LinkedIn post that challenges this directly, under 200 words, direct tone."
The process post
"Here's a framework I use in coaching: [describe it in 3-4 sentences]. Write a LinkedIn post that explains this clearly to other coaches, in plain language, under 250 words. Use short paragraphs, no bullet lists."
The personal story post
"Here's a coaching experience I had: [2-4 sentences about what happened and what you learned]. Write a LinkedIn post in first person that tells this story and ends with one clear takeaway. Under 250 words, conversational tone."
Storing your style preferences
In ChatGPT's paid plan, you can save custom instructions that apply to every conversation. This saves you from repeating your tone preferences each time. A useful setup:
"I'm a coach who writes LinkedIn content for other coaches. My writing style is direct and conversational. I don't use bullet points unless necessary. I avoid corporate language. I start posts with a statement, not a question. I keep posts under 220 words unless a longer format is specifically appropriate."
Once that's saved, your prompts can be shorter because the context is already there.

Frequently asked questions
How long should my prompt be?
Long enough to include: the raw content, a tone instruction, a format constraint. Usually 3-6 sentences. Longer prompts are not always better. Specific prompts are better.
What if the first output is unusable?
Ask for a rewrite with a different angle, or change one constraint. "Rewrite this but start with the observation rather than a general statement" often produces a noticeably different draft. Iteration is part of the workflow.
Should I always use the same prompt format?
Not exactly. The core elements stay the same: real input, tone instruction, format constraint. But vary the post type and angle to avoid your content becoming repetitive.
Can I use ChatGPT for carousel content too?
Yes. Prompt it for a numbered list format: "Write this as 6 slides for a LinkedIn carousel, each slide one main point, under 20 words per slide." You still need to design the actual carousel but the content structure comes quickly.
How do I stop AI posts from all sounding the same?
The editing step is where you add distinctiveness: your specific details, your opinions stated directly, your rhythm. Generic prompts produce generic output. The more specific and personal your starting input, the more distinctive the result after editing.
Is there a faster way to do this once I have a workflow?
CoachCraft has the prompting and editing workflow built into the platform, along with publishing and scheduling. If you're finding yourself spending too much time on the ChatGPT-to-LinkedIn pipeline, a dedicated tool worth looking at.
