What it does
Who’s it for This template is ideal for creators, bloggers, and automation enthusiasts who want to auto-generate blog posts from AI-generated content — without lifting a finger. Whether you're running a tech blog, AI newsletter, or just want to keep your WordPress site fresh, this workflow does the heavy lifting. --- How it works This n8n workflow automatically publishes WordPress posts using trending content from Reddit RSS feeds (like /r/artificial and /r/MachineLearning), enhanced with AI writing and royalty-free images. 1. RSS Feed Trigger: Fetches new Reddit posts every minute from multiple AI-related subreddits. 2. AI Blog Writer: Uses an LLM (Groq / GPT-4o) to convert Reddit titles + content into a full blog article (title, content, category, tags, image keyword). 3. Image Generator: Queries the Pexels API using the keyword provided by the AI to fetch a relevant blog image. 4. Category & Tag Manager: Automatically creates or reuses categories and tags in WordPress. 5. WordPress Publisher: Posts the article in draft or published form — complete with featured image and metadata. Everything is dynamically generated — no hardcoded text or API keys! --- How to set up Estimated time: 15–20 minutes You’ll need: 🧠 Groq or OpenAI API key (for AI article generation) 🖼️ Pexels API key (for fetching featured images) 📰 WordPress API credentials (with media + post permissions) Customization via Sticky Notes: Choose your own RSS feeds (or subreddit URLs) Modify the AI prompt to match your writing style Set post status (draft or publish) Add your WordPress API URL and credentials --- Requirements Free n8n account (or self-hosted instance) API credentials (Groq/OpenAI, Pexels, WordPress) Working WordPress site with REST API access Sticky notes explaining: Setup instructions AI prompt format Required credential names
