Stop waiting for engineers. Build your own prototypes.
If you can pitch it, you can build it.
What is Codex? It's OpenAI's AI coding agent. You talk to it in plain English, it writes the code. Download the free desktop app for Mac or Windows. Think of it as a developer you can direct — no programming knowledge needed.
The only course taught INSIDE Codex that turns business ideas
into working prototypes in hours. Zero coding required — only business thinking.
You'll finish with something you can show off, share, and put on your portfolio.
Build a fully working web app for NovaBrew, a fictional D2C coffee startup. Customers take a taste quiz and get personalized blend recommendations — complete with shareable results. Then deploy it to a live URL anyone can visit.
Internal dashboards, customer-facing calculators, landing pages with interactive features, automated workflows — whatever your business needs. Deploy it live and share the link. Portfolio-ready.
If you've ever said "I just need an engineer to build this quick thing" — this course is for you.
"Zero coding required — only business thinking."
No complicated setup. No configuration files. Just you and an AI that codes for you.

No. Zero coding required. The entire course is designed for people who have never written a line of code. You'll direct AI using plain English — the same way you'd brief a contractor or manage a team.
Codex is an AI coding agent made by OpenAI. It's a free desktop app for Mac and Windows where you open a project folder and have a conversation. You describe what you want in plain English, and Codex builds it. No coding required. It works with a free ChatGPT account — no paid subscription or API keys needed.
About 4–5 hours total, split across four modules. Go at your own pace — do it in one sitting or spread it across a week.
A working web app deployed to a live URL (on GitHub Pages, free) that you can text to anyone. Plus a GitHub portfolio and a case study. Not a certificate — actual proof you can build things.
That's literally Module 3. The capstone is designed for you to build your own idea — whether it's a startup MVP, an internal tool, or a side project.
