Introduction
WordPress is a powerful platform for building AI-powered SaaS (Software-as-a-Service) businesses. By integrating AI tools, payment systems, and a credit-based model, you can create a profitable online service. In this guide, we’ll walk through the steps to build and monetize an AI SaaS business using WordPress.
Step 1: Choose an AI Service
Before setting up your SaaS business, decide what kind of AI-powered tool you want to offer. Some popular AI-based SaaS ideas include:
- AI Content Generator (like ChatGPT)
- AI Image Enhancer
- AI-Powered SEO Tools
- AI Voice Converter
- AI Code Generator
Example: AI-Powered SEO Keyword Generator
We’ll use OpenAI’s API to create an AI-based SEO Keyword Generator.

Step 2: Set Up WordPress & Install Required Plugins
Required Plugins:
- MemberPress (for subscription-based payments)
- myCred (for credit-based usage)
- WPForms (for AI input forms)
- Custom Plugin for AI API Integration
Step 3: Develop a Custom WordPress Plugin for AI API Integration
1. Create a Plugin Folder & Main File
In the wp-content/plugins/ directory, create a new folder: ai-keyword-generator. Inside it, create ai-keyword-generator.php and add the following code:
[collapsible_blur points=”100″]
<?php
/*
Plugin Name: AI Keyword Generator
Description: A simple AI-powered keyword generator using OpenAI API.
Version: 1.0
Author: LearnWithSaiteja
*/
if (!defined(‘ABSPATH’)) exit;
function ai_keyword_generator_form() {
echo ‘ Generate Keywords ‘;
if ($_SERVER['REQUEST_METHOD'] == 'POST' && !empty($_POST['keyword'])) {
$keywords = ai_generate_keywords($_POST['keyword']);
echo '<p><strong>Generated Keywords:</strong> ' . implode(", ", $keywords) . '</p>';
}
}
add_shortcode(‘ai_keyword_generator’, ‘ai_keyword_generator_form’);
function ai_generate_keywords($input) {
$api_key = ‘replace_api_key’;
$url = “https://api.openai.com/v1/completions”;
$data = json_encode([
"model" => "text-davinci-003",
"prompt" => "Generate 10 SEO keywords for: $input",
"max_tokens" => 100
]);
$args = [
'body' => $data,
'headers' => [
'Content-Type' => 'application/json',
'Authorization' => 'Bearer ' . $api_key
]
];
$response = wp_remote_post($url, $args);
if (is_wp_error($response)) return ["Error generating keywords"];
$body = json_decode(wp_remote_retrieve_body($response), true);
return explode(", ", $body['choices'][0]['text']);
}
[/collapsible_blur]
✅ Now, add the shortcode [ai_keyword_generator] to any WordPress page to display the AI tool.
Step 4: Monetization Methods
1. Subscription-Based Access (MemberPress)
- Install & configure MemberPress.
- Create a subscription plan (e.g., $9.99/month for unlimited AI keyword generation).
- Restrict access to the AI tool page.
2. Credit-Based System (myCred Integration)
- Install myCred plugin.
- Charge users 1 credit per AI request.
- Modify the plugin to deduct credits:
[collapsible_blur points=”20″]
if (function_exists(‘mycred_subtract’)) {
mycred_subtract(‘keyword_usage’, get_current_user_id(), 1, ‘AI Keyword Generation’);
}
[/collapsible_blur]
Step 5: Promote & Scale
- SEO Optimization: Rank for keywords like “AI SEO tools” & “AI content generator.”
- Affiliate Marketing: Partner with bloggers & influencers.
- Email Marketing: Offer a free trial in exchange for emails.
- Upgrade AI Model: Integrate GPT-4 for better keyword suggestions.
