01What Is Codex Sites and How Does It Work?
Codex Sites is a new feature from OpenAI inside Codex. It turns your typed idea, plan, or rough notes into a real working website or app. Then it hands you a link you can share with anyone.
That link is the whole trick. The people you send it to can open it, click around, and use it right away. No hosting setup.
No figuring out how to put it online. It is just there.
Before this, when AI built something for you, you got a file sitting on your computer. Nobody else could see it. Now you get a live link today.
02What Makes Codex Sites New and Different
The biggest change is that building and sharing happen in one step. A year ago, AI tools could write a little code, but you had to host it and fix it yourself. Most people quit at that step.
Sites knocks that wall down.
It is not just a picture of a website. It is a real working one. Buttons work.
Forms work. People can actually do things on it.
OpenAI did not try to do all the hosting alone. They teamed up with big website builders like Wix, Replate, Lovable, Figma, and Mergent. Your finished thing lands on solid ground built to handle real visitors.
It is not a toy that breaks when 10 people show up.
03How to Get Started with Codex Sites
- Make sure you are on a business or enterprise plan with Codex. Sites rolls out to those plans first.
- Open Codex and start a new project.
- Type out your idea, your plan, or your rough notes in plain words.
- Press the button to build. Codex turns your text into a real website or app.
- Get the link Codex gives you.
- Share that link with your team, customers, or clients.
You do not touch code at any point. If you can type a text message, you can use this.
04How to Use Codex Sites with Real Examples
In the episode, Julian shows an example. Instead of writing a long, boring page, you tell Codex to build an interactive page. Someone can click through coaching calls, daily tutorials, and the member map.
You get one link, and it becomes a chat message you can send.
For your own business, pick one thing that is stuck as a boring document. It could be a plan, a guide, or a simple offer. Hand that to Codex.
You will get back a live page people can actually click.
You can also use the new annotations feature. It lets you point at one specific part of a document and say, "Change this part." It fixes just that piece and leaves the rest alone. For example, you could point at the top section of a page and ask for it to be clearer or more exciting.
05Results and Numbers from the Episode
Codex now has more than five million people using it every week. That is up six times since February.
About one in five users are not developers. They are regular knowledge workers, marketers, sales folks, and business owners. That non-coder group is growing more than three times faster than the coders.
The speed is wild. You can dream up a new lead magnet on Monday morning and have a live clickable version of it by Monday lunch, with a link ready to share. That changes how you sell, how you teach, and how fast you can test an idea.
06Tips, Limits, and Mistakes to Avoid
One big tip: start small. Pick one thing in your business that is a boring document. Plan it, guide it, or make a simple offer.
Get one win before you try bigger projects.
Avoid the old habit of just describing your idea. The bar is rising. When everyone can ship a working tool in an hour, talking about your idea will not be enough.
People who actually build and share will pull ahead.
Do not wait. Sites is rolling out to business and enterprise plans first, but it will open to everyone. The people who get it now will have a head start.
07Who Should Use Codex Sites and Why It Matters
Codex Sites is for anyone who has a job to do, not just coders. It is built for the salesperson who wants a page to send to a customer, the coach who wants a link people can open, and the business owner who knows what their customers need.
OpenAI is aiming this at regular work. They dropped six job-focused tools inside Codex for data work, creative work, sales, product design, and investing. They even said the challenge now is helping companies fold these tools into how they already work.
For the regular worker, Sites gives the one thing they always needed: the share button. It is the front door to a future where you pitch a plan by sending a working version of it.
