Summarize RSS articles and publish AI images to WordPress and social media

Who it's for

This n8n workflow is designed for content creators, bloggers, digital marketers, and social media managers who want to fully automate their content distribution pipeline. The workflow creates an end-to-end multi-channel publishing system that fetches new articles from an RSS feed (e.g., Paul Graham's essays), extracts and AI-summarizes the content, generates ultra-realistic visual prompts, creates stunning images via OpenAI (DALL-E), and instantly publishes the article along with the generated image across WordPress, Facebook, Instagram, LinkedIn, Telegram, and Discord simultaneously.

Features

• Automatically fetches new articles via RSS feeds
• Filters irrelevant items using regex rules
• Extracts full article content (title + body text)
• Splits long articles and generates AI-powered summaries (GPT-4.1-mini)
• Combines original titles with clean summaries
• Converts summaries into detailed image generation prompts
• Creates images using OpenAI DALL·E
• Publishes full posts directly to WordPress
• Generates SEO-optimized featured images with metadata
• Downloads, resizes (5000×5000), and uploads images to WordPress media library with alt text and captions
• Posts images with captions to Facebook Pages via Graph API
• Publishes Instagram posts using the 2-step Graph API process
• Sends formatted posts to Telegram channels
• Publishes to LinkedIn personal profiles and company pages
• Shares rich media posts to Discord channels

Requirements

• OpenAI API: Generates summaries, image prompts, and DALL·E images
• WordPress API: Creates posts, uploads media, and sets featured images
• Facebook Graph API: Publishes to Facebook Pages and Instagram (2-step process)
• LinkedIn API: Posts to personal profiles and company pages
• Telegram Bot API: Sends images with captions to channels
• Discord Bot API: Sends rich embed posts with title, summary, and imag

Important Notes

• The workflow processes items one by one using a loop; the top output must remain connected to ensure continuous iteration.
• A regex filter is used to allow only valid article URLs and prevent malformed links.
• WordPress image flow must stay in order: Create Post → Download Image → Resize (5000×5000) → Upload Media → Update Metadata → Set Featured Image.
• Instagram publishing requires a two-step Graph API process: create media object → publish using returned ID.
• Dynamic expressions (e.g., {{ $('Loop Over Items').item.json.title }}) must remain unchanged for proper data mapping.
• WordPress automatically generates a URL-safe slug from the article title to handle special characters.
