Automate WordPress Blog Creation with AI & n8n

What this workflow does

This workflow helps you create WordPress blog posts fast using AI.

It solves the problem of spending many hours writing and editing posts for different readers.

The workflow makes a blog post in three reading levels and adds a nice image automatically.

You get ready drafts in WordPress that save you time and keep content good for many readers.

Tools and services used

• OpenAI API: Creates and rewrites blog content in HTML and Markdown.


• Google Drive: Saves original draft backups as text files.


• WordPress REST API: Creates and manages blog posts and media.


• Pollinations.ai HTTP service: Generates featured images from the blog title.


• Telegram Bot API: Sends notifications about workflow success or errors.

Inputs, processing steps, and outputs

Inputs

• User provides a blog topic through the Set Blog Topic node.

Processing steps

1. The Create Structured Blog Post node asks OpenAI to write an HTML blog with title and content in JSON.

   
   

2. The Structured Output - JSON and Separate Title & Content nodes extract and clean the title and content.

   
   

3. The Tiltle & Content Exist? node checks if title and content are present.

   
   

4. The HTML to Markdown node changes the blog into Markdown for easier rewriting.

   
   

5. Three AI Agent nodes rewrite the blog at Grade 9, Grade 5, and Grade 2 reading levels.

   
   

6. Each rewritten version is validated again by If nodes.

   
   

7. The Google Drive node saves the original draft as a backup.

   
   

8. The Create Wordpress Post node makes a draft post using the Grade 9 version.

   
   

9. The pollinations.ai HTTP Request node creates a featured image from the blog title.

   
   

10. The Upload Image to Wordpress node uploads the image.

    
    

11. The Set Image on Wordpress Post node sets the featured image for the post.

    
    

12. The Telegram nodes send messages on success or if errors happen.
