How to Integrate ChatGPT into WordPress: Full 2025 Guide for Smart Websites

Why Add ChatGPT to WordPress?

AI is no longer optional — it’s a competitive edge. By integrating ChatGPT into your WordPress site, you can create intelligent chatbots, dynamic content generators, personalized product recommendations, and more.

Whether you’re running a blog, eCommerce store, or service website, this guide by Muhammad Tanzeel Ur Rehman at MT Web Experts will walk you through how to integrate ChatGPT with WordPress, both with plugins and direct API methods.

We’ll also cover real use cases and how to control the AI to match your brand’s tone.

Option 1: Use a WordPress Plugin for ChatGPT Integration (No Coding Required)

Recommended Plugin: AI Engine by Jordy Meow

Steps:

1. Go to Plugins > Add New in your WordPress dashboard
2. Search for “AI Engine” by Jordy Meow
3. Install and activate it
4. Navigate to Meow Apps > AI Engine in your sidebar
5. Enter your OpenAI API key (available at OpenAI platform)
6. Choose options like chatbot, content generator, or custom GPT forms

This plugin allows full customization of prompts, model version (e.g., gpt-3.5 or gpt-4), tone, and even temperature settings.

Option 2: Embed ChatGPT as a Widget or Iframe

If you have access to a standalone chatbot built with GPT (like a third-party frontend), you can embed it using an HTML block or widget.

Steps:

1. Get the embed code from your third-party provider
2. In WordPress, create or edit a page
3. Add a Custom HTML block or use a widget area
4. Paste the iframe code
5. Preview and publish

While this method is fast, it offers limited customization and may not integrate deeply with your user data.

Option 3: Use OpenAI’s API to Build a Custom ChatGPT Solution

For developers or advanced users, using OpenAI’s official API gives you full control over the interaction.

Basic Setup:

1. Sign up at OpenAI
2. Generate an API key
3. Install a plugin like WPCode or write a custom plugin

Example PHP Code:

function mt_chatgpt_query($prompt) {
  $api_key = 'YOUR_OPENAI_API_KEY';
  $url = 'https://api.openai.com/v1/chat/completions';

  $response = wp_remote_post($url, array(
    'headers' => array(
      'Authorization' => 'Bearer ' . $api_key,
      'Content-Type'  => 'application/json'
    ),
    'body' => json_encode(array(
      'model' => 'gpt-3.5-turbo',
      'messages' => array(
        array('role' => 'user', 'content' => $prompt)
      )
    ))
  ));

  return wp_remote_retrieve_body($response);
}

Bonus: How to Customize the GPT Personality

Most plugins and APIs allow you to include a system message to define the tone:

{"role": "system", "content": "You are a helpful assistant that responds in a fun and engaging tone."}

This lets your chatbot stay consistent with your brand.
