OpenAI Codex: Build ANYTHING!

Key Takeaways

Open AI Codex just changed everything. You can now build almost anything with it. Apps, landing pages, full business systems, and you don't need to write most of the code yourself. This is the update that makes Codex actually dangerous. And by the end of this video, you'll know exactly how to use it. Okay? So, Open AI Codex, most people think of it as just a coding tool. Like, you type something in, it spits out some code. Cool. But what just dropped is completely different. Codex now has plugins, and plugins change absolutely everything about how you use this tool. I'm going to show you what they are, how to install them, how to build your own, and then we're going to use one live to build something real for the AI Profit Boardroom. So, stick around because this gets really good. So, first, what even is a plugin in Codex? Think of it like this. Before plugins, Codex was a smart assistant that could write code. After plugins, Codex becomes a whole team. Each plugin is a little bundle. It packages skills, app connections, and tool configs all together in one place. You install it once, then Codex just knows how to use it. It's like giving your AI a new superpower every time you install something new.

And here's the part that blew my mind. These aren't just little add-ons. They're full workflows. So, instead of telling Codex step-by-step what to do every single time, you install a plugin, and it already knows the steps. It already knows the tools. It already knows how to connect to the apps you use. You just say what you want, and it handles the rest. You can install plugins from the official Codex plugin directory. That's a marketplace Open AI built where you can browse ready-made plugins for things like web building, project management, and integrations, or you can build your own. And that's where it gets really fun, which I'll show you in a second. So, how do you actually install a plugin? It's stupidly simple. You open the Codex app, you go to the plugins directory, you browse what's there, and you hit install. That's it. Once it's installed, you can see it inside Codex by typing our plugins. And from that point on, Codex knows how to use those new skills automatically. You don't have to set anything up. You don't have to configure libraries or install packages. The plugin handles all of that behind the scenes. And here's where it gets powerful for for people running actual businesses. Let's say you want Codex to build a landing page for the AI Profit Boardroom. Before plugins, you'd have to give it a ton of instructions, tell it what framework to use, what structure to follow, how to style it, what sections to include. Now, you just install a web builder plugin, and it already knows all of that. You just say, "Build me a high-converting landing page for a premium AI automation community called the AI Profit Boardroom." And watch it go. Before we go further, quick one, if you're watching this and thinking, "Wow, I want to use tools like Codex to actually build and grow my business with AI." Then you need to check out the AI Profit Boardroom. It's our private community for entrepreneurs and creators who are serious about using AI automation to get more done faster. We go deep on tools like this. We share the exact workflows, and we help each other implement it properly. So, if you want to learn how to save time and automate your business with AI tools like Open AI Codex, the link is in the description. Come join us inside. Now, here's the part most people are going to sleep on. You can build your own plugins, and this is where Codex becomes a real business tool, not just a coding toy. Inside Codex, there's a built-in skill called a plugin creator. You use that to scaffold a new plugin folder. It gives you a simple structure to work with. You've got a plugin.py file, which is your manifest, basically the ID card for your plugin. You've got a skills folder where you drop in your reusable workflows written as simple markdown instructions. And then, you've got optional files for connecting to external tools and apps. So, let me paint you a picture of how how we'd use this for the AI Profit Boardroom. Imagine we create a plugin called APB Growth Kit. Inside the skills folder, we build a skill called landing page writer. The skill tells Codex, "Whenever someone asks for a landing page, use this structure, focus on these benefits, include these sections, and always write copy that drives people to join the AI Profit Boardroom." So, next time someone on our team opens Codex and types, "Build a landing page for our new AI automation workshop." It doesn't just spit out generic stuff. It follows our exact brand voice, our structure, our offer every single time. And you can go even further. You can add a file called nomcp.json that connects your plugin to external tools like GitHub, Notion, or any API you use. So, now your plugin isn't just writing code, it's pushing it to GitHub, pulling in data from Notion, and integrating with your actual business stack. That's when Codex stops feeling like an AI assistant and starts feeling like an extra team member. Let me show you what this actually looks like in practice. Say we want to build two things for the AI Profit Boardroom. One, a landing page that converts. Two, a simple internal tracker to manage new member leads. Here's how we do it with Codex and plugins. First, we'd use an official web scaffolding plugin from the Codex directory. We'd install it, then prompt Codex with something like, "Build a Next.js landing page for the AI Profit Boardroom. The page should show the amazing value of AI automation, explain the key benefits of joining our community, and drive visitors to sign up. Make it clean, fast, and high-converting." Codex builds the whole thing. The sections, the copy structure, the styling. Done in minutes. Then for the lead tracker, we'd use our custom APB plugin. We prompt it with, "Create a simple internal dashboard for tracking new member leads. Include columns for name, email, date joined, and lead source. Connect it to our GitHub repo so the team can access it." And Codex would build it using the plugin's connection to hook into GitHub automatically. No setup from us. It just works. Then you deploy the landing page to something like Vercel or Netlify with a single command, and now you've got a live landing page and a working internal tracker built in under an hour without writing most of the code yourself. That's the power of Codex plus plugins. There's a few more things worth knowing about the new Codex update. First, multi-agent workflows. Codex can now run sub-agents that work in parallel. So, instead of doing everything one step at a time, you can have one agent researching, one designing, one coding, all at once. For complex builds, this cuts the time down massively. Second, there's a faster model built into Codex now for lighter tasks like browsing your codebase and reviewing big files. The more powerful model still handles the heavy thinking, but having this split makes the whole thing faster and cheaper to run, especially on bigger projects. Third, you can now sync plugins at startup. So, every time someone opens Codex, all the right plugins load automatically. No one has to remember to install anything. It's all ready to go. For teams building together, this is massive. Here's the big picture. Most people think coding and AI tools are just for developers, but Codex with plugins is for anyone building a business. You don't need to know how to code. You need to know what you want to build and what outcome you're driving toward. The plugin handles the how, you handle the what and the why. For communities like the AI Profit Boardroom, this means we can build faster, ship faster, and test ideas faster. Landing pages, internal tools, automation workflows, lead trackers, member onboarding systems. All of it built with Codex, customized with our own plugin, and connected to the tools we already use. That's a real competitive advantage, and most people aren't doing this yet. Okay, so that's Open AI Codex plugins. This is one of the biggest updates in AI coding tools this year, and most people have no idea it exists. So, share this with someone who needs to hear it.
