AI Blog Generator For WordPress Posts

AI Blog Generator For WordPress Posts

This workflow automates the creation of blog post drafts by combining an n8n form, OpenAI's language model, and WordPress. It's designed for content creators, marketers, and bloggers who want to overcome writer's block and streamline their content pipeline. Instead of starting from a blank page, you submit a topic, target audience, and key points through a simple form, and the workflow generates a structured, well-written draft ready for your review and editing in WordPress.

The core value of this workflow is its efficiency. It transforms a time-consuming task—writing a first draft—into a quick, structured process. By keeping the output as a 'draft' in WordPress, it ensures that nothing goes live without your final approval, maintaining editorial control. The workflow also includes thoughtful touches like automatic retries for the AI call and clear instructions for troubleshooting, making it robust and user-friendly.

Workflow Nodes and Steps

Here is a step-by-step breakdown of the workflow:

1. Setup — read me first (Sticky Note) — Provides an overview, setup time, level, and links to the creator's site.
2. How it runs (Sticky Note) — Explains the workflow's logic and data flow.
3. If something breaks (Sticky Note) — Offers guidance on error handling and setting up an error workflow.
4. Draft Request Form (Form Trigger) — This node hosts a web form with fields for 'Topic', 'Audience', and 'Key points (one per line)'. It starts the workflow when the form is submitted. (No auth required for the form itself).
5. Write Draft (OpenAI) — This node uses the gpt-5.6-terra model to generate the blog post. It receives the form data and uses a carefully crafted prompt to produce a title and body in HTML format. (API Key auth).
6. Split Title and Body (Code) — A JavaScript code node that parses the AI's response, extracting the title and the HTML body content into separate fields for the next step. (No auth).
7. Create WordPress Draft (WordPress) — This node creates a new post in WordPress with the generated title and content, setting the status to 'draft' so it's not published immediately. (Application Password auth).

Setup Instructions

To use this workflow, you will need the following:

1. OpenAI Account: You need an API key from OpenAI. Create an account at platform.openai.com, go to the API keys section, and create a new secret key. Add this key to the 'Write Draft' node's credentials.
2. WordPress Site: You need a self-hosted WordPress.org site (not WordPress.com). To connect, you'll need to generate an Application Password. In your WordPress admin dashboard, go to Users > Profile and scroll down to the 'Application Passwords' section. Create a new one and use those credentials in the 'Create WordPress Draft' node.
3. Activate the Workflow: After connecting your credentials, activate the workflow in n8n. The 'Draft Request Form' node will provide a production URL. Bookmark this URL to access your form.

Use Cases and Variations

• Content Calendars: Integrate this with a Google Sheets node to log all generated drafts and their statuses.
• Multi-Platform Publishing: Add a step to convert the HTML draft to Markdown and send it to other CMSs like Ghost or Dev.to.
• SEO Optimization: Insert a node to analyze the generated content for keywords or readability scores before creating the WordPress post.
• Team Collaboration: Instead of a public form, trigger the workflow from a Slack command or email, allowing your team to submit topics without leaving their communication tools.
• Different Content Types: Modify the prompt in the 'Write Draft' node to generate other content formats like product descriptions, social media posts, or email newsletters.
