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

This n8n workflow automates the creation and publishing of WordPress blog posts by pulling trending content from Reddit RSS feeds, such as AI-related subreddits like /r/artificial and /r/MachineLearning. It leverages Groq AI (or GPT-4o) to transform Reddit titles and content into full-fledged blog articles, including optimized titles, body text, categories, tags, and image keywords. Royalty-free images are then fetched from Pexels API based on AI-generated keywords, ensuring visually appealing posts.

The workflow triggers every minute on new RSS items, processes them through AI enhancement, manages WordPress categories and tags dynamically (creating if needed), and finally publishes complete posts with featured images and metadata. Users can customize post status (draft or publish), RSS feeds, AI prompts, and credentials via sticky notes for easy adaptation.

Ideal for bloggers, content creators, and automation enthusiasts, it saves hours of manual writing and image sourcing, keeping sites fresh with high-quality, relevant content. Requires Groq/OpenAI, Pexels, and WordPress API keys; setup takes 15-20 minutes. Perfect for tech blogs, AI newsletters, or any WordPress site needing consistent posting without effort.
