🚀 The Rise of the GPT Store
In 2026, the world of artificial intelligence has gone beyond just using ChatGPT — now you can actually create and sell your own Custom GPT. Whether you’re a freelancer, developer, or digital creator, this new opportunity can help you earn passive income while building your personal AI brand.
In this guide, I’ll show you step-by-step how to design, train, and sell your own GPT, even if you’ve never done it before.
What Is a Custom GPT?
A Custom GPT is basically your personalized version of ChatGPT — trained for a specific task, audience, or niche.
For example:
- A GPT that writes blog posts in your tone and style
- A customer support GPT for a business
- A “Fitness Coach GPT” that gives workout advice
The possibilities are endless. OpenAI’s platform now allows you to configure prompts, rules, tone, and even upload your own datasets.
Why You Should Build a Custom GPT
The demand for AI automation tools is exploding, and small businesses, agencies, and content creators are ready to pay for ready-made GPT solutions.
By building your own:
- You position yourself as an AI expert
- You can sell GPT access via OpenAI’s GPT Store
- You can integrate it into websites, apps, or client workflows

Step-by-Step: How to Create a Custom GPT
1. Define Your Niche
Pick one focus — like marketing, design, fitness, or coding.
Your GPT should solve a specific problem, not “do everything.”
2. Open OpenAI’s Custom GPT Builder
Go to chat.openai.com/gpts.
Click “Create” → set your name, description, and personality.
Upload any reference files or instructions that help shape its style.
3. Test Your GPT Thoroughly
Try different user prompts.
Ask yourself: “Would I pay for this?”
If it’s fast, consistent, and useful — you’re ready.
4. Publish and Sell
- List your GPT on OpenAI’s GPT Store
- Or sell it directly through your website or portfolio
- You can also embed it in WordPress using AI plugins (like Integrate ChatGPT into WordPress)
💡 Tip: Always include a short demo video or screenshots to build trust.
