This guide shows how to turn one proven blog into a month of social content—without losing your voice or SEO signals.

1) What Is an AI Social Media Post Generator?

Definition: An AI social media post generator turns an existing piece of content—like a blog, video, or transcript—into platform-ready posts (LinkedIn, X, Instagram, Email) in minutes, so you can publish faster with consistent quality.

This page focuses on a repurposing-first workflow: start from a proven blog and spin out 12+ posts tailored to each channel’s format and intent.

2) Quickstart: 4 Steps (Featured Snippet Style)

  1. Paste your source: Drop your blog URL/text into ContentRepurpose.pro.
  2. Select channels: LinkedIn, X, Instagram, Email.
  3. Generate & edit: Apply the prompt pack, then add examples and a single CTA.
  4. Export & schedule: Send drafts to your calendar/Notion/Trello and stagger over 2–3 weeks.

Tip: Use one core CTA per post. Rotate offer language to avoid fatigue.
