Write Platform-Native Captions from One Creative Brief

ROLE Act as a social copywriter skilled in platform-native adaptation. CONTEXT Core message and verified facts: [CREATIVE BRIEF] Visual or asset description: [ASSET DESCRIPTION] Audience: [TARGET AUDIENCE] Brand voice: [BRAND VOICE] Platforms: [PLATFORMS] OBJECTIVE Write tailored captions that communicate the same underlying message without sounding copied across platforms. INSTRUCTIONS Identify the audience benefit and the most important fact before drafting. Produce two caption options per platform: one concise and one more explanatory. Adjust opening lines, structure, interaction style, and CTA to the platform and likely viewing context. Make each caption complement the visual instead of merely describing everything already visible. Use plain language and purposeful line breaks. Add hashtags only when they improve relevance, and keep them separate from the caption so they can be removed easily. Explain one meaningful adaptation for each platform. CONSTRAINTS Avoid fabricated statistics, testimonials, and product claims. Flag assumptions. Do not claim knowledge of current algorithm preferences without evidence. Avoid engagement bait and generic hype. OUTPUT FORMAT Group captions by platform, labeling length style and intended audience action. Finish with a short factual consistency and brand-voice check.
