# Cross-Platform Caption Variator

Takes one core post idea and generates properly adapted captions for multiple platforms at once, matching each platform's length, tone, and formatting norms.

## Prompt

You are a social media copywriter who understands that the same idea needs different treatment on each platform.

Core post idea/content: {{core_idea_or_content_summary}}
Platforms needed: {{list_of_platforms}}
Brand voice: {{brand_voice_description}}
Call to action: {{desired_cta}}

For each platform listed, write a caption that:
1. Matches that platform's typical length and pacing (e.g., punchy and short for X/Twitter, more narrative and paragraph-friendly for LinkedIn, hook-plus-value for Instagram, native slang-appropriate for TikTok).
2. Includes the call to action phrased naturally for that platform's norms (e.g., 'link in bio' for Instagram vs. a direct link for X/Twitter vs. a comment-based CTA for LinkedIn).
3. Suggests 3-5 relevant hashtags where the platform convention calls for them (skip hashtags entirely for platforms where they hurt reach, like LinkedIn or Facebook, and note why).
4. Flags any platform-specific formatting notes (e.g., where to put line breaks, whether emojis fit the brand voice on that platform).

## Best for

Solo creators and small marketing teams repurposing one piece of content across multiple platforms who don't have time to manually rewrite captions from scratch for each one.

## How to use

- Describe the core content or idea once, along with which platforms you're posting to.
- Specify your brand voice and the call to action you want included.
- Copy each platform-specific caption directly under its respective post.
- Use the formatting notes to adjust line breaks and emoji use per platform before publishing.

## Customization tips

- If you're repurposing a video, mention that so captions account for on-screen text versus caption-only content.
- Add a note if a specific platform account has a different, more casual sub-voice than your main brand voice.
- Request A/B caption variants for any one platform if you want to split-test different angles.

## Example input

Core idea: We just launched a new AI skill pack for cold outreach. Platforms: Instagram, X/Twitter, LinkedIn, TikTok. Brand voice: Confident, practical, no fluff. CTA: Check it out via link in bio.

## Example output

Four distinct captions: a short punchy X post with 1-2 hashtags, an Instagram caption with a hook line, value bullet, and 'link in bio' CTA plus 5 relevant hashtags, a LinkedIn post written in paragraph form with no hashtags and a comment-based CTA, and a TikTok caption written for on-screen pairing with native short-form phrasing.
