Key Insights
You’re in the right place if you use ChatGPT, Claude, Claude Code, Claude Co-work, or Codex, but don’t know which one you should use for business and how. Because in this video, we’re talking about using AI agents effectively. Specifically, we’re talking about Codex, OpenAI’s agent tool, which is like Claude Code, except it’s an easy-to-use interface for doing knowledge work and coding work. In this video, we’re going to be breaking down the seven core capabilities of Codex, OpenAI’s AI agent super app, each with real-world use cases, so that by the end, you know exactly what it can do and where it fits in your workflow. Let’s get started. So, this right here is Codex. This is a clean interface for AI agents that can fully control your computer. At first glance, it kind of looks like ChatGPT or Claude, because you can create a chat, but they’re not exactly the same. When you chat on ChatGPT or Claude and upload files, those files are actually stored in the cloud. With Codex, all of the files that you upload to Codex or that you create with Codex are stored on your computer. Codex is made to do any task that you might want to do on a computer. You can create a motion graphics video. You can create beautiful landing pages, and directly inside Codex, you can generate images that you can place in your site. On Codex, you can also create more complex games and 3D simulations. You can also create mobile apps with a front end and back end with a professional design. You can also create desktop apps in just a few prompts. You can ask GPT 5.5 to create you an Excel sheet after doing a ton of research, and it can create spreadsheets with multiple slides. It can also create any type of Word doc with many different charts, and you can also create presentations directly inside Codex and export them to Canva or any other tool you want. And I haven’t even mentioned yet that Codex can fully control my computer, and it can also control the browser. But, this is something we’ll talk about a little bit later. As we go through the main seven different capabilities of Codex, you’ll realize that it is truly a super app that does any coding task or any knowledge work task. Let’s not waste any time. Let’s hop into capability number one. So, the first capability that Codex has is full file access. You see, when I use ChatGPT, all of the files that I give to ChatGPT or that ChatGPT generates are stored in the cloud. However, when we use Codex, all of the files that are created or the files that I give to it are stored on your computer. And the agent inside Codex has full access to your computer. Let me show you. In my downloads folder, I have a folder called receipts to process. And we just have 60 different little photos of receipts that I’ve added to this folder. I can simply ask Codex, “In the downloads folder, you’ll see my receipts that I need to process. I want you to analyze them in an Excel sheet and create charts that helps me visualize the types of transactions and any other patterns that you notice.” So, we can choose our model, which is GPT 5.5 high, and we can run it. And the agent, because it has full file access, it can access any file on my computer, it’ll find the relevant folder and complete the task. And you can see here, it found the target folder, which is users Riley Brown downloads receipts to process with only 53 receipts. I’m going to OCR those, and so we’re going to extract the text from those receipts, classify and categorize each transaction. Now, it’s creating an Excel workbook on my computer that we can open up in Codex. All right. So, after 7 minutes, it is now done and we can very easily just open this Excel project up directly inside Code X and you can see that it has created this file. We can see there’s a dashboard, the total spend is 25,982. We see receipts, category summary, payment summary, and we can see all the different trends, the spend by payment method. We can see the monthly trends. This is an Excel sheet an
