Key Takeaways
- Turns one idea into ready-to-post social captions tuned to a platform.
- Works in ChatGPT, Claude, Gemini, and most AI assistants.
- Set the platform, topic, and tone in the brackets.
- Review, personalise, and add your own voice before posting.
Keeping up with social content is relentless. This prompt takes a single idea and generates platform-appropriate posts — with the right length, hook, and tone — so you have options to choose from instead of a blank caption box.
The prompt
Act as a social media copywriter. Create posts for the following. Platform: [e.g. LinkedIn, Instagram, X, Facebook] Topic: [what the post is about] Goal: [e.g. drive engagement, promote a product, share a tip] Brand voice: [e.g. friendly and expert, playful, professional] Write 3 post options suited to the platform's style and length. Each should have a strong hook in the first line, deliver value or interest, and end with a clear call to action. Suggest 3-5 relevant hashtags where appropriate.
How to use it
Choose the platform (a LinkedIn post reads very differently from an X post), your topic, goal, and brand voice. Paste it in and you will get three ready-to-adapt options with hooks and hashtags. Pick the strongest and make it yours.
Tips for best results
- Name the platform — length and tone differ a lot between LinkedIn, X, and Instagram.
- Define your voice — "witty and casual" vs "authoritative" changes everything.
- Ask for a hook variation — "give me 5 alternative first lines".
- Keep it authentic — edit so it sounds like you, not generic marketing.
A quick example
Prompt it for platform "LinkedIn", topic "why small teams should adopt AI early", goal "spark discussion", voice "practical and encouraging", and you will get three posts with scroll-stopping first lines and a question that invites comments.
