Building Custom GPTs
Build powerful custom GPTs from scratch. Master instructions, knowledge files, actions, testing, and publishing to the GPT Store in 8 practical lessons.
What You'll Learn
- Design a custom GPT from concept to published product using the GPT Builder
- Write effective system instructions that control GPT behavior reliably
- Apply knowledge files to give GPTs specialized domain expertise
- Build GPT Actions that connect to external APIs and services
- Evaluate and iterate on GPT performance through systematic testing
- Create a publishing and monetization strategy for the GPT Store
Course Syllabus
Prerequisites
- ChatGPT Plus, Team, or Enterprise subscription
- Basic familiarity with ChatGPT (sending prompts, getting responses)
What You’ll Learn
Custom GPTs are the fastest way to build AI-powered tools without writing a single line of code. Instead of crafting the perfect prompt every time you use ChatGPT, you build a GPT once — with instructions, knowledge, and capabilities baked in — and it works perfectly every time.
Companies use custom GPTs as internal tools: onboarding assistants, customer support bots, data analysts, and meeting summarizers. Entrepreneurs publish them on the GPT Store to reach millions. And individuals build personal GPTs that handle everything from meal planning to tax preparation.
This course takes you from zero to a published, polished custom GPT. You’ll learn the GPT Builder interface, master instruction writing, attach knowledge files, configure actions, test systematically, and publish to the store.
Who This Course Is For
- Professionals who want to automate repetitive ChatGPT workflows into reusable tools
- Entrepreneurs looking to build and sell AI-powered products without coding
- Teams that need internal AI tools for specific business processes
- AI enthusiasts who want to go beyond basic prompting into building AI applications
Course Structure
8 lessons, each 12-15 minutes, with hands-on building exercises. By the end, you’ll have a fully functional custom GPT published and ready for users.
Frequently Asked Questions
Do I need to know how to code?
No coding required for most custom GPTs. You build them through natural language instructions and a visual interface. Actions (API connections) use a configuration format, but we walk through it step by step.
What ChatGPT plan do I need?
You need ChatGPT Plus ($20/month), Team, or Enterprise to create custom GPTs. Free ChatGPT users can use GPTs others have created but cannot build their own.
Can I make money from custom GPTs?
Yes. The GPT Store offers revenue sharing based on engagement. You can also use GPTs as lead generation tools for consulting or services. We cover monetization strategies in detail.
How long does it take to build a custom GPT?
A simple GPT takes 10-15 minutes. A polished GPT with knowledge files and tested instructions takes 2-4 hours. This course gives you the skills to build both.
