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.
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.
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).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.
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.
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.
