Auto-Generate WordPress Blog Posts from Reddit RSS with Groq AI & Pexels Images

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!
