Turn Any Idea Into a Working Website With ChatGPT Work and Codex

In this guide, you'll learn how to turn a website idea into a working prototype using the new ChatGPT Work and Codex app (which uses the new GPT-5.6 models).

• Founders and creators who want to turn a rough website idea into a working prototype.
• Operators and researchers who need to collect directory data while another agent builds the site.
• Anyone with a content-driven project who wants to move from a plan to a usable website in one desktop app.

We built an Astro.js directory prototype for roguelike and roguelite games on Nintendo Switch. It has a homepage, filters, detail pages, structured game data, and images that the coding agent can use to populate the site.

The same setup works for tools, products, books, services, local businesses, or any collection with consistent fields.

• The updated ChatGPT desktop app with ChatGPT Work and Codex visible.
• A new project folder for the PRD, research files, images, and Astro.js site.
• One website-directory idea with a clear theme and audience.

When the site is ready, check whether the new Sites feature is available in the app. Tell Codex:

Publish this finished website using the Sites skill. Deploy it and return the public URL.

If Sites is available, OpenAI will deploy and host the site for you. That is the natural next step for this workflow: plan the site, gather the content, build the prototype, then publish it from the same app.
