This n8n workflow transforms blog articles into tailored social media posts across LinkedIn, X (Twitter), and Reddit, using AI for content generation and image creation.

Workflow Breakdown

  1. Trigger and Input: Manual trigger starts the flow. Sets article URL (e.g., Salesforce blog post).
  2. Fetch Content: HTTP request retrieves the page. HTML node extracts body content.
  3. AI Processing: OpenAI (GPT-4.1) analyzes content, extracts title and summary, generates unique posts:
    • LinkedIn: Professional, 120-220 words, emojis, hashtags.
    • X: Concise (<280 chars), engaging, hashtags.
    • Reddit: Conversational, 100-300 words, community-focused.
    Outputs JSON with posts, image prompts, hashtags.
  4. Pause: Wait node delays for processing.
  5. Image Generation: OpenAI creates images from prompts for X and LinkedIn.
  6. Posting:
    • LinkedIn: Shares post with article link, title, description, image.
    • X: Uploads image, tweets post.
    • Reddit: Posts to subreddit (u_leeseifer) with title and text.

This automation streamlines content promotion, driving engagement back to the original article.
