AI Content Repurposing Tool

Build a tool that turns one piece of content into 10+. Blog to Twitter threads, YouTube to LinkedIn posts, podcast to newsletter. Full build guide.

Creators know they should be omnipresent—on Twitter, LinkedIn, YouTube, newsletters, podcasts. But creating unique content for each platform is exhausting. Most either burn out trying to be everywhere or neglect platforms where their audience lives. The smartest creators repurpose, but doing it manually takes hours.

Built for Developers, Solo Founders, Side Hustlers, Marketers, Creators.

OpusClip hit 5M+ users and raised $30M Series A on the video-clip angle (TechCrunch 2024)—category validated at scale.

Gary Vee built a $200M+ agency on the repurposing thesis and teaches the pyramid publicly; playbook is established, tools are still fragmented.

Paste a blog post URL and instantly get: a Twitter thread, LinkedIn post, email newsletter intro, Instagram caption, YouTube video script outline, and podcast talking points. Each version is optimized for that platform's style and format.

  1. 1. Project Setup

    Create a Next.js app for an AI Content Repurposing Tool.
    
    Features:
    - Input section: URL input (auto-fetches content), or paste text directly
    - Platform selection checkboxes: Twitter thread, LinkedIn post, Newsletter, Instagram, YouTube outline
    - Output section: tabbed view with each platform's version
    - Copy button for each output
    - Save to library feature for future reference
    
    Clean, modern UI with Tailwind. Focus on fast time-to-value.
  2. 2. Core Feature

    Create API route that takes content and generates platform versions:
    
    For each platform, use Claude with specific prompts:
    - Twitter thread: "Convert to engaging thread. Hook in tweet 1, key points in 2-8, CTA in last. Under 280 chars each. Add relevant emojis sparingly."
    - LinkedIn: "Convert to professional LinkedIn post. Use line breaks, add 3-5 relevant hashtags. Personal tone, insights focus."
    - Newsletter: "Write engaging intro paragraph that makes readers want to continue. Include key takeaway teaser."
    - Instagram: "Create caption with hook, value, CTA. Add 20-30 relevant hashtags in comment format."
    - YouTube: "Create video script outline with hook, 3-5 main points, and call to action."
    
    Return all versions in JSON.
  3. 3. URL Parsing

    Add smart URL content extraction:
    
    - For blog URLs: Use Mozilla Readability to extract article content
    - For YouTube URLs: Fetch transcript using youtube-transcript-api or similar
    - For podcast URLs: Support Apple Podcasts and Spotify links, extract show notes
    - For Twitter URLs: Expand thread content
    
    Handle edge cases: paywalled content (show error), very long content (summarize first), non-English (detect and translate if needed).
