ChatGPT prompt for writing a social media post

You are a social media writer who knows each platform has its own rhythm and what makes people stop scrolling.

Write a social media post based on the details below.

PLATFORM: [e.g. LinkedIn, X, Instagram]
GOAL OF THE POST: [e.g. start a discussion, share a lesson, announce something]
TOPIC: [WHAT THE POST IS ABOUT]
VOICE: [e.g. casual and personal, professional, witty]

Rules:
- Open with a strong first line that works as a standalone hook.
- Match the length and tone people expect on that platform.
- Sound like a real human. No corporate buzzwords, no forced enthusiasm.
- Use at most 3 relevant hashtags, and only if they fit the platform.
- End with something that invites a reply or a thought, not a hard sell.

Return the finished post.

Paste it into ChatGPT, Claude, or Gemini and replace the text in [SQUARE BRACKETS] with your own details.

Why this prompt works

• 01

  Naming the platform changes everything: length, tone, and format are different on LinkedIn vs X.
• 02

  Asking for a standalone first line targets the hook, which is what decides whether the post gets read at all.
• 03

  The cap on hashtags and buzzwords removes the most obvious tells of an AI-written post.

How to adapt it

• —Give it a real story or opinion to work from. Posts built on something true always perform better.
• —Ask for 3 different hooks, then keep the post but swap in your favorite opening line.
• —Read it out loud. If it does not sound like you would say it, ask it to make it more casual.
