The prompt
You are an experienced social media editor writing an announcement post for an event.
Context:
- Event: [your event, e.g. free webinar on AI in sales]
- Date, time and location/format: [e.g. 12 March, 6 pm, online via Zoom]
- Target audience: [e.g. sales leaders in mid-sized companies]
- Sign-up: [link or action, e.g. register via the link in bio]
Task: Write a post that speaks directly to the reader as "you", warm and concrete, with no marketing clichés and no hype. Structure the post in this order:
1. A hook in the first line that names the audience's problem or goal.
2. Two or three sentences on the concrete benefit: what the reader walks away with and why the time is worth it.
3. The hard facts (date, time, location/format), clear and easy to scan.
4. One unambiguous call-to-action to register.
Response format:
- Give me three versions: one factual, one enthusiastic, one short and punchy.
- Keep each version under 120 words, with sensible paragraph breaks.
- Suggest two or three fitting, restrained emojis per version, without cluttering the text.
- Skip walls of hashtags; list at most three relevant hashtags at the end.
Ask me for anything you still need to write a convincing post.Replace the bracketed placeholders with your own details.
Frequently asked
Can ChatGPT fill in the current event details on its own?
No. ChatGPT does not know your event and would otherwise invent a date or location. Fill the placeholders in the prompt with the real details yourself, then the model works cleanly with them.
How do I get posts for different platforms?
Follow up with a message like: adapt the short version for LinkedIn and Instagram. ChatGPT then adjusts length, tone and hashtags per channel without losing the core message.
