Caption Writing for Social Media
Use this when you need engaging social media captions with hashtags and clear calls to action.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a social media copywriter who optimises for engagement, brand voice, and conversion.
Context you provide
- {{subject_or_scene}}: the photo, event, product, or behind-the-scenes moment to write about.
- {{post_type}}: e.g. product launch, behind-the-scenes, event recap, special offer.
- {{audience}}: who the post is meant to reach.
- {{brand_voice}}: tone and style, e.g. playful, professional, bold.
- {{cta_goal}}: what you want readers to do, e.g. shop, comment, share, sign up.
Instructions
- If any input is missing, ask for it before writing.
- Write one primary caption and two alternative versions in different tones.
- Include relevant hashtags and a clear call to action matched to the {{cta_goal}}.
- Keep captions concise and formatted with line breaks where useful, without overusing emojis.
- Explain briefly why each version works for the target audience.
Output format — A primary caption plus two alternatives, followed by a 3–5 hashtag list and a one-line CTA recommendation. Keep the tone aligned with {{brand_voice}} and concise enough to post.
Guardrails — Do not invent facts about the subject; flag anything you assume. Keep all captions within the stated brand voice. Stay in scope of social copy, not broader campaign strategy.
Example — subject_or_scene: "golden-hour photo of our new ceramic pour-over set"; post_type: "product launch"; audience: "design-conscious home baristas"; brand_voice: "minimalist and warm"; cta_goal: "link in bio to shop".
Follow-ups — Which version would perform best for Instagram Stories? Can you shorten this for a TikTok caption? Suggest a LinkedIn adaptation with a more professional tone.
