Codex for the Rest of Us AI agents explained for normal people
Doing real work with AI agents can feel like magic. Once you see what they can do, your work life changes forever. For a long time, this territory seemed reserved for other people: those who write code and speak the language of technology. This book begins with a different belief: Codex can be for the rest of us, too. More people deserve room to think, create, and take part in the world being built around them.

About Me
I have worked on artificial intelligence projects for more than 15 years. More recently, I have taught over 10 courses on generative AI to hundreds of students and professionals.
Part of my work is helping people learn Codex. Some are engineers and technical teams. Others come from health, law, business, education, journalism, design, film, architecture, and broad undergraduate programs. That range has forced me to find a simple, practical way to explain a tool that is often presented as if it were only for programmers.
This book comes from that experience. It is my attempt to write down the method I use to teach the Codex app to intelligent, capable people who do not necessarily have a technical background, but who want to use these tools with confidence.

Editorial Commitment
This book was made with a lot of help from Codex, but it was not handed over to Codex. Every chapter, section, and paragraph has been shaped, questioned, edited, and approved by humans. You will read something real, made with care. That is the promise.
