How to Ask ChatGPT to Write a LinkedIn Post That Doesn't Sound Like AI

Short answer: give ChatGPT the real story (what happened and the one lesson), who you're writing for, a word limit, and a list of banned clichés. Ask for 3 hook options. Then add one detail only you know before you post. Without those ingredients you get "Thrilled to share…" and a wall of hashtags.

Why AI LinkedIn posts all sound the same

LinkedIn rewards a style AI copies easily: one-line paragraphs, inspirational wrap-ups, "humbled and honored." When everyone's posts come from the same default, readers recognize it in one line.

Start with your story, not the topic

  • The raw story: what happened, in your messy notes.
  • One lesson: the single takeaway.
  • Audience: peers, hiring managers, customers?
  • Length: under 150–200 words.
  • Banned phrases: "thrilled to share," "humbled and honored," "game-changer," "delve," "in today's fast-paced world."
  • Ending: one real question, not "Agree?"

Before and after

Before:

write me a linkedin post about how i got promoted make it inspiring

After:

Role: You are a ghostwriter for professionals who hate cringe LinkedIn posts. Task: Write a post about my promotion to [title] at [company]. Context: Key lesson: [I said yes to the unglamorous projects]. Audience: peers in [field]. Notes: """[what actually happened]""" Format: 3 hook options (one line each), then the post: under 150 words, short paragraphs, one specific moment, and a closing question. Constraints: No "humbled and honored," no hashtag wall (max 2), no emojis. Use only facts I gave you.

Why it works: the lesson gives the post a point, the specific moment makes it believable, and the banned list removes the phrases people scroll past.

Other post types

  • Sharing an article: "Summarize into a post under 1,300 characters. Lead with the most surprising takeaway, add my opinion: [opinion], credit the source by name, and add no facts that aren't in the text."
  • Job search: "Write a short 'open to work' post for [role] with 2 concrete results and what I'm looking for. No desperation."
  • Lessons learned: "3 lessons from [project], each with one specific example. No listicle emojis."

Edit before you post

  1. Change the first line yourself.
  2. Add one detail only you know.
  3. Cut 20%.
  4. Ask ChatGPT: "List every factual claim so I can verify it."
  5. Read it out loud. If you wouldn't say it to a coworker, rewrite it.
