Course Description

ChatGPT Work Course: Work With an AI Agent on Your Computer

Please note that this course is not affiliated with or endorsed by OpenAI. OpenAI is not responsible for the content or delivery of this course. Any references made to OpenAI are purely for informational purposes and do not imply endorsement or affiliation with OpenAI.

Learn how to use ChatGPT Work (formerly OpenAI Codex) as a practical AI assistant for real work on your own computer. This course shows you how Codex can read files, organize folders, create documents, improve websites, work with code, and automate recurring tasks.

Unlike a normal chatbot like ChatGPT, Codex works directly inside project folders. You describe the outcome you want, and Codex can inspect files, make changes, run commands, and produce finished work that stays on your machine.

What You Will Learn

By the end of this course, you will know how to:

  • Install and set up the Codex desktop app

  • Open local folders as Codex projects

  • Use Codex for both coding and non-coding tasks

  • Organize messy files and generate structured spreadsheets

  • Redesign a basic website with AI assistance

  • Make changes inside an existing code repository

  • Review Codex’s work safely before trusting the output

  • Create a recurring automation, such as a daily brief

  • Understand when to use Codex instead of ChatGPT or the OpenAI API

Who This Course Is For

This course is designed for:

  • Beginners who want to use AI for practical computer tasks

  • Professionals who work with documents, files, spreadsheets, or websites

  • Developers who want an AI coding agent inside their workflow

  • Creators, freelancers, and small business owners who want to automate repetitive work

  • Anyone curious about how agentic AI tools like Codex are changing productivity

You do not need to be an experienced programmer. The course includes coding examples, but it also shows how Codex can help with everyday knowledge work.

Course Projects

Inside the course, you will complete hands-on examples such as:

  • Organizing a folder of messy invoice PDFs

  • Renaming files and creating a clean CSV summary

  • Turning an outdated website into a modern static page

  • Editing an existing code project with Codex

  • Setting up a recurring daily brief automation

Why Learn ChatGPT Work + Codex?

ChatGPT Work represents a new way to work with AI. Instead of copying text back and forth from a chat window, you can give an agent access to a folder and ask it to produce real files, make edits, and complete multi-step tasks.

This makes Codex useful for software development, and ChatGPT Work for everyday work like file organization, reporting, writing, research, and automation.

Requirements

To follow along, you need:

  • A ChatGPT account

  • The ChatGPT desktop app

  • A Mac or Windows computer

  • Basic comfort working with files and folders

No API key is required unless you want to build your own app with the OpenAI API.

Course Outcome

By the end, you will understand how to use Codex as a hands-on AI agent for real projects. You will know how to give clear instructions, review the results, iterate when something is wrong, and decide which tasks are worth delegating to Codex.

Instructor Details

Valentin Despa

I teach IT professionals what I wish I'd known earlier.

My foundation is built on years in the trenches as an Agile Enterprise Software Developer, engineering solutions for everything from fast-paced start-ups and SMBs to large global corporations. I hold recognized roles as an AWS Community Builder, Postman Supernova, and GitLab Hero, alongside a deep history of securing and building major open-source projects.

For over a decade, I've taken that real-world experience and quietly built one of the largest learning communities around API tooling, test automation, and DevOps practices. What started as a side YouTube channel turned into hundreds of thousands of learners, conference talks, and team workshops at companies most IT professionals have heard of.

The thread through all of it is the same: take something that looks intimidating and break it down so anyone can understand it in plain language.

Lately, I've been spending more time on practical AI in the workplace. I look at how teams can leverage AI for both everyday knowledge work and hands-on IT engineering, like coding and testing. I focus on cutting through the hype to figure out how AI actually helps IT professionals get work done, build, and ship faster. New formats, same approach.

It was short and hands on tips that lets me practice. Would love to have such short sessions to develop my AI skills as a none Technical user.

By VinothDevakumar on 9/11/2026

Topic subject says AI agent but what inside is more or less Codex features like plugins, automation and skills. there is nothing about AI Agent

By Sven Halm on 8/11/2026

All the information I needed in a short amount of time, along with some examples of how to do it. I love it when things are explained simply and quickly. Most of the time, I just need to understand how something works, the ideas on how to use it will come later.

By Tricky Mouse on 8/4/2026

Great course! One suggestion: it would be valuable to add a module on AI security and handling personal data safely.

By Joe H on 8/3/2026

Short and sweet. Course covers a lot of the basics you will already know but also covered some new features I was not aware of. Thanks!

The content was excellent and well structured, making it easy to follow and apply. I found it extremely helpful in practice. Highly recommend it to anyone considering signing up.

By Gheorghi Ostapenco on 7/3/2026

Another gem from Valentin. A highly necessary course given the current reality, covering the most critical aspects of everyday AI agent implementation. Highly recommended for everyone.

By Vishal Singh S on 6/28/2026

The content was well-structured, easy to follow, and very informative. Highly recommended for Non-Developers looking to learn this topic.
