  “Summarize insights and suggest 3 new content ideas.”

6. 🔁 Repurpose Content Across Platforms

Turn one blog post or podcast into a week of content using AI:

• Blog → Carousel post → LinkedIn caption → Tweet thread → Instagram Reel → Newsletter
• Use tools like Repurpose.io or Descript to convert video/podcast to clips
• ChatGPT Prompt: “Turn this blog post into a carousel for Instagram and a LinkedIn post.”
