How to Copy ChatGPT to LinkedIn Without Sounding Like AI

Your network can tell when a post was written by ChatGPT. Here's how to use AI for LinkedIn content that actually sounds like you.

Let's be honest: everyone uses ChatGPT for LinkedIn posts now.

The problem? Everyone can tell. You've seen the posts:

  • "I'm thrilled to announce..." (nobody talks like this)
  • "In today's fast-paced world..." (instant AI detector)
  • Perfect grammar, zero personality
  • Generic insights that could apply to any industry
  • That weird emoji-heavy formatting ChatGPT loves

This guide shows you how to:

  • Use ChatGPT as a drafting tool (not a replacement for your voice)
  • Clean up AI tells before posting
  • Format content properly for LinkedIn
  • Maintain authenticity while saving time

Remove AI tells instantly

DeGPT strips the phrases that scream "ChatGPT wrote this" from your LinkedIn drafts.

Why ChatGPT posts stand out (for the wrong reasons)

LinkedIn users have developed a sixth sense for AI content. Here's what triggers it:

The vocabulary problem

ChatGPT has favorite words and phrases that humans rarely use in casual writing:

  • "Leverage" instead of "use"
  • "Navigate" instead of "deal with"
  • "Delve into" (almost nobody says this)
  • "It's worth noting that..."
  • "In conclusion..." (who ends a LinkedIn post like an essay?)

The structure problem

ChatGPT loves:

  • Perfect parallel structure in lists
  • Exactly three points (always three)
  • A "hook," then "body," then "call to action"
  • Emoji at the start of every bullet point

Real people write messier. That messiness is part of what makes content feel human.

The specificity problem

AI writes in generalities. Humans write about specific experiences. "Last Tuesday, I..." is immediately more believable than "In my experience..."

Step 1: Prompt ChatGPT correctly

The output is only as good as the input. Instead of "Write a LinkedIn post about leadership," try:

"Help me draft a LinkedIn post about a lesson I learned managing my team this week. The situation: [specific thing that happened]. The insight: [what I realized]. My tone is casual and direct—I don't use corporate jargon. Keep it under 200 words."

Key elements:

  • Specific context – Give ChatGPT real details to work with
  • Your voice – Tell it how you actually sound
  • Constraints – Word count, things to avoid
  • "Draft" – Signals you'll be editing it, not posting verbatim

Step 2: Clean the AI tells with DeGPT

Even with good prompts, ChatGPT output usually needs cleaning. DeGPT can automatically remove or replace common AI phrases.

Using the Chrome Extension

  1. Install the DeGPT extension
  2. In ChatGPT, click the DeGPT button on your draft
  3. Enable "Remove AI tells" to strip obvious ChatGPT phrases
  4. Copy the cleaned version

What DeGPT removes:

  • ✅ "I'm thrilled/excited to announce..."
  • ✅ "In today's fast-paced/ever-changing world..."
  • ✅ "It's worth noting that..."
  • ✅ Excessive corporate jargon
  • ✅ Overly formal transitions

Step 3: Add your human fingerprint

After cleaning, you still need to make it yours. Here's how:

Add a specific detail

"Last Tuesday," "during our Q4 planning," "at a coffee shop in Austin"—these details are impossible for AI to invent and immediately signal authenticity.

Include a small imperfection

A casual aside, a sentence fragment, starting a sentence with "And" or "But"—real humans write imperfectly. ChatGPT doesn't.

Use your actual vocabulary

If you say "that's wild" in real life, say it in your post. If you never say "furthermore," delete it.

Reference something only you would know

A conversation with a specific person, a book you're reading, something that happened at your company. This is your authenticity signal.

Step 4: Format for LinkedIn

LinkedIn has specific formatting requirements that differ from ChatGPT's default output:

The hook (first 2-3 lines)

LinkedIn only shows ~210 characters before "see more." Your opening line needs to make people click. ChatGPT often buries the hook.

  • Before: "In my 15 years of experience in the tech industry, I've learned that..."
  • After: "I almost quit my job last month. Here's what changed my mind:"

Line breaks matter

LinkedIn doesn't render markdown. Bullets become plain text. Use line breaks instead:

  • Short paragraphs (1-2 sentences)
  • Line breaks between thoughts
  • Avoid walls of text

Emoji usage

ChatGPT tends to overdo emojis. On LinkedIn:

  • One or two is fine
  • Every bullet point having an emoji looks AI-generated
  • When in doubt, remove them

The workflow: ChatGPT → DeGPT → Edit → Post

  1. Draft in ChatGPT

    Give it context, your voice, and constraints. Ask for a draft, not a final product.

  2. Clean with DeGPT

    Remove AI tells and clean up formatting. Takes 5 seconds.

  3. Add your fingerprint

    Specific details, your vocabulary, a personal story element. This is what makes it yours.

  4. Format and post

    Check the hook, add line breaks, moderate the emojis. Then post.

Total time: 5-10 minutes. You get the speed benefit of AI without the authenticity cost.

When NOT to use ChatGPT for LinkedIn

Some posts should be 100% you:

  • Major career announcements – New job, promotion, leaving a company
  • Personal stories – Vulnerable posts, life lessons, failures
  • Controversial takes – If you're making a bold statement, it should be yours
  • Responses to current events – Time-sensitive, needs your genuine reaction

Use AI for the posts that share knowledge, tips, or insights. Write personally for the posts that share you.
