01What the ChatGPT Codex update is and how it works

The ChatGPT Codex update turns ChatGPT from a chatbot into a worker that can use your computer for you. It clicks, types, opens apps, and even remembers how you like to work. This is new, big, and much easier than you think.

In the past, ChatGPT only told you how to do a task. Now Codex actually does the task. It can see your screen, move your mouse, fill forms, and copy data between apps.

You don't need to be a coder. If a task is mostly clicking, reading, typing, and moving information, Codex can do it.

02Four big features in the update

The update brings four tools at once: computer use, the Codex Chrome extension, personalized memory, and Chronicle. Each one solves a different problem.

  • Computer use: Codex sees your screen and controls your mouse and keyboard on Mac and Windows. It can open apps, click buttons, and type inside them.
  • Chrome extension: Codex works in your browser tabs. It doesn't take over your whole browser, and it works with tabs you are already signed into.
  • Personalized memory: Codex remembers your style, recurring tasks, and preferences, so you do not repeat yourself every time.
  • Chronicle: This tool builds memories by looking at your recent screen activity, so Codex knows your context without you typing it out.

These features are rolling out across Europe, the UK, and Switzerland, and they work together to make Codex feel like a teammate.

03How to get started with the update

Getting started with the ChatGPT Codex update takes a few simple steps. You do not need any special skills.

  1. Open ChatGPT and go to the Codex section.
  2. If you are in Europe, the UK, or Switzerland, turn on personalized memory in the settings. It starts off turned off in those regions.
  3. Install the Codex Chrome extension for browser tasks.
  4. If you want to use Chronicle, turn it on in settings, but start with less private material.
  5. Try a simple task, like asking Codex to pull numbers from a webpage and summarize them.

That is it. Once you set it up, Codex is ready to work. Remember to keep an eye on it when it does important tasks.

04Using computer use and the Chrome extension

Here is how you can use the update in real work. For computer use, say you have numbers in three places: your email tool, your community page, and your traffic page. Normally, you would open each one, copy, paste, and try to combine them.

That takes 20 minutes of clicking.

With Codex, you just say, "Go pull today's signups and traffic from these three pages and give me one clean summary." Codex goes and does it while you grab a coffee. For the Chrome extension, you can ask Codex to read a blog post and write five short posts for sharing. Or, if you get the same question from 10 people in your inbox, you can say, "Draft a friendly reply that explains the benefits." Codex writes the draft, you read it, and you send it.

05How personalized memory and Chronicle work

Personalized memory makes Codex remember your style and preferences. For example, the first time you ask it to write a welcome email, you explain that you like it warm, simple, and with no fluff. The second time, it already knows.

By the tenth time, it feels like working with someone who gets you.

Chronicle goes a step further. It watches what you are working on, so Codex knows your context without you typing it. This is powerful, but it also means Codex sees your screen.

OpenAI says to use it carefully. Turn it on, but do not point it at your most private things on day one.

Together, memory and Chronicle help Codex get better every time you use it. The more you use it, the more time you get back.

06What this means for your business

This update matters because ChatGPT stopped being just an answer machine. Now it does work for you. You do not need coding skills.

Tasks that used to require scripts or hiring someone can now be handled by AI.

For your business, you can have Codex pull daily numbers, update your customer list, or watch what competitors are doing. For content, you can have it gather research, draft video chapters, or write posts for different platforms. All that busy work that eats your day is gone.

The real win is not one cool automation. It is that Codex remembers how you work and improves each time. The people who learn to use these hands now will be ahead a year from now.

07Risks and limits to know

Be honest about the risks. AI can misclick. It can misread a page.

So for anything important, you stay in the seat and approve what it does. Do not let it run wild with your passwords. Keep your hand near the wheel.

Treat Codex like a smart helper, not a robot you fully trust on day one. Some websites will block it, too. That is just where things are right now.

It is powerful, but it is still early.

Here is a quick summary: Computer use does the work, memory remembers you, the Chrome extension makes it easy, and Chronicle learns from your screen. Put it together and you have ChatGPT that can take action and help you run your day.

08Who should use this update

This update is for normal business owners who want to save time, not for programmers. If you spend hours clicking, copying, and typing, Codex can take those tasks off your hands. It is especially useful for pulling reports, answering repeat emails, and creating content drafts.

If you want to learn how to set it up properly, there are resources like the AI Profit Boardroom and the AI Success Lab. These communities offer step-by-step guides, ready-to-use prompts, and coaching calls. The notes from this episode are available there.

However, the core message is simple: ChatGPT has hands now. The people who learn to use them will save hundreds of hours and stay ahead.
