LinkedIn post prompt: free ChatGPT template
Updated · By Robert Breen
Use this when you want to post on LinkedIn as yourself, about something you've seen in your own work, and sound like a person rather than a brand. A generic request returns one sentence per line, a dramatic opener, a made-up lesson and a stack of hashtags. This prompt starts from a real moment you describe and the one point you want to make, so the AI shapes your story instead of inventing one.
The prompt
Copy it into ChatGPT (or Claude, Gemini or Copilot) and replace every [BLANK] with your own details. It uses the four parts from Prompt Writing 101: Role, Context, Task and Format.
Role: You are helping [YOUR NAME], [YOUR ROLE] at [BUSINESS], write a LinkedIn post in their own voice. Context: The post is for [AUDIENCE]. What happened, in my words: [STORY]. The one point I want readers to take away: [POINT]. Use only what's in my story. Don't invent numbers, clients, dialogue or results, and don't exaggerate what happened. Task: Write one LinkedIn post that opens with the most concrete detail from the story, explains the point in plain words, and ends with a question for readers. Format: Under 180 words. Short paragraphs of one to three sentences, not one sentence per line. First person. No emoji, no "Here's the thing," no "Let that sink in." At most 2 hashtags at the end.
Fill in the blanks
[YOUR NAME]- Whose profile it will be posted from.
[YOUR ROLE]- Your job title, so the voice fits: owner, office manager, sales lead.
[BUSINESS]- Your business name and what you do.
[AUDIENCE]- Who you want reading it, such as owners of small service businesses in your area.
[STORY]- What happened, told the way you'd tell a friend. Concrete details beat summaries. Leave out names of clients who haven't agreed.
[POINT]- The one takeaway, in a sentence. If you have two points, write two posts.
Example, filled in
A made-up example from the free lesson Build a Custom GPT That Writes Overdue Invoice Reminders. Maple Street Bookkeeping is the made-up bookkeeping firm in the overdue invoice reminder lesson. Its owner wants to post about a new client's receipt habit.
Role: You are helping Beth, owner at Maple Street Bookkeeping, a small bookkeeping firm, write a LinkedIn post in their own voice. Context: The post is for owners of small service businesses in our area. What happened, in my words: in January a new client, a two-van cleaning company, handed us a year of receipts in three grocery bags. Sorting them took most of a week. We set them up to snap a photo of each receipt the day they get it, and their February books were done by the 5th. The one point I want readers to take away: a small daily habit beats a big yearly cleanup. Use only what's in my story. Don't invent numbers, clients, dialogue or results, and don't exaggerate what happened. Task: Write one LinkedIn post that opens with the most concrete detail from the story, explains the point in plain words, and ends with a question for readers. Format: Under 180 words. Short paragraphs of one to three sentences, not one sentence per line. First person. No emoji, no "Here's the thing," no "Let that sink in." At most 2 hashtags at the end.
What a good answer looks like
- An opener built on your detail ("three grocery bags of receipts"), not "I've been thinking a lot about..."
- Your story as you told it, with no new numbers and no quoted client line you never wrote.
- Normal paragraphs that read easily on a phone.
- A closing question that invites replies instead of "Follow me for more."
How to check it before you use it
An AI draft can sound right and still say something you never told it. Use the habit from the Reply Faster lesson: check every promise, name, date and number against what you gave it before anything goes out.
- Check every detail against your story: numbers, dates, who did what. If you told it in general terms, the post shouldn't suddenly say "saved 40 hours."
- Remove anything that identifies a client who hasn't agreed. Describe the type of business, not the name (PII applies to clients too).
- Read it out loud. If a sentence is something you'd never say, ask for that line again in plainer words.
- Make sure your point is one you'd defend in the comments.
Why this prompt works
The Story blank is the Context: details only you have. Without it, the AI fills the space with the most common LinkedIn patterns, which is why so many posts sound alike. The Format bans the specific habits you don't want, and prompt constraints like these work better than asking it to "sound authentic."
