How to Use AI to Write Blog Posts Automatically in WordPress

AI isn’t just hype anymore—it’s a legit tool in a developer’s workflow. One of the coolest use cases? Letting AI generate blog content for you. Whether you’re maintaining a business blog, a niche directory, or a personal dev journal (like this one), AI can give you a serious head start.

🤖 Why Even Use AI for Writing?

You don’t always have time to write
Drafting is the hardest part
AI can structure posts, generate headlines, and even add Markdown or Gutenberg-ready markup
It’s great for SEO-focused content, tutorials, changelogs, or product updates

🛠️ Tools I Use

ChatGPT: Perfect for prompts, outlines, and writing with your tone
WordPress Block Editor: Supports pasting formatted output directly
Code Snippets or Plugin Hooks: Optional automation
Custom Block (future idea): A “Generate intro via AI” field for posts

⚙️ How to Automate the Flow

1. Write a structured prompt

“Write a 500-word blog post about how to use functions.php to customize WordPress performance, aimed at experienced developers.”
2. Include variables dynamically

You can pass post_title, category, tone, and length into the prompt

3. Paste into the block editor

Ask AI to return Gutenberg-style markup:

<!-- wp:heading -->
<h2>Intro</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>This post explores...</p>
<!-- /wp:paragraph -->

4. Clean up manually (or train your prompt)

You still polish the post. AI is great for first drafts.

🧪 Optional: Automate Further via API

You could take this even further with:

A custom admin page that lets you generate content via prompt
Auto-insert draft posts using wp_insert_post()
Use the OpenAI API or a plugin like AI Engine

$post_id = wp_insert_post([
  'post_title'   => 'How to Use AI with WordPress',
  'post_content' => $ai_generated_content,
  'post_status'  => 'draft',
  'post_type'    => 'post'
]);

🧠 Final Thoughts

This post? Mostly written by AI. 😏

I gave it a topic, a few bullets, and some notes about what I wanted—and it handled the rest. I cleaned it up, added some Gutenberg structure, and done.

You don’t have to use AI to replace your writing, but it’s brilliant for kickstarting content—especially if you’re like me: busy, opinionated, and allergic to blank pages.
