ChatGPT Sites lets you create, preview, publish and share interactive websites and lightweight apps by describing them in ChatGPT. You build them in Work on ChatGPT web, or in Work or Codex in the desktop app, by asking for a website or typing @Sites. It's available on Plus and Pro and in supported Business and Enterprise workspaces. One thing to know before you start: OpenAI says every deployment URL is a production URL, so save a version and review it before you deploy.
Most small businesses don't need ChatGPT to replace their main website. Where Sites shines is the smaller stuff: a resource hub for clients, an event page, a simple dashboard, an interactive version of a pitch. Things you'd never brief a developer for, but would use if they existed.
Here's how it works and where the traps are, based on OpenAI's help article on Sites.
What you can build
OpenAI's own examples include turning a presentation into an interactive pitch, a data export into a business performance dashboard, and team resources into a customer support app or an employee learning hub. In supported Business and Enterprise workspaces, Sites can also use visitors' connected apps, for example an issue tracker that shows each person their own tasks.
Who can use ChatGPT Sites
| Plan or setting | What OpenAI says |
|---|---|
| Plus and Pro | Available, with no fixed limit on the number of Sites |
| Business | Sites is on by default; access also depends on your role |
| Enterprise | Available in supported workspaces; public publishing is off by default and needs an admin |
| ChatGPT Classic desktop app | Not available; you need the latest ChatGPT app |
Usage and storage limits still apply across your Sites. Each Site's database can store up to 10 GB, and file storage has no fixed limit per Site. If you hit a shared limit, you may not be able to create a new Site even if it wouldn't use storage.
How to build your first Site
- On the web, select Work. In the desktop app, select ChatGPT and then Work, or select Codex.
- Describe the website you want. Include the word "website" in your prompt or mention @Sites.
- Add the content, files, data, links and any constraints it should use.
- Review the private preview ChatGPT generates.
- Ask for changes until the Site is ready to share or publish.
A clear brief saves rounds of edits. Here's one for a client resource page:
Copy this prompt
Use @Sites to build a simple resource hub for my clients from the files I've attached.
Group resources by topic, add a search box, and write one line on when to use each one.
Use only the materials I've supplied and ask me about anything missing.
Show a friendly message when a search finds nothing.
Save a version for me to review before anything is published.
The catch: deploying means going live
This is the line in OpenAI's guide I'd underline twice. When you deploy, ChatGPT generates a Site URL, and every deployment URL is a production URL. There's no separate staging link. To check changes without touching the live Site, save a version first and deploy only after you've reviewed it.
The same care applies to content. OpenAI asks you to use only material you have permission to share and to choose an audience that matches it. A dashboard built from client data shouldn't be public.
Using your own domain
Where custom domains are available, you can point a domain you control at your Site. Sites doesn't register domains for you, so you must already own it and be able to change its DNS records.
- Open the Site's settings and select Add domain.
- Enter the domain or subdomain you want to use.
- Copy the DNS records Sites gives you and add them at your domain provider.
- Wait a few minutes, then refresh the domain status in Sites.
A subdomain, such as resources on your main domain, is usually the cleanest choice. It keeps your main website untouched.

Sites with connected apps
For teams, the clever part is that each visitor uses their own connected accounts and existing permissions. You build the tool once, publish it privately to your workspace, and every colleague sees their own data. OpenAI suggests testing with one teammate before sharing it widely, and reviewing the app access each Site requests before authorising it.
Good first Sites for a small business
- A client onboarding page that gathers your welcome pack, forms and FAQs in one place
- A searchable library of your guides, templates or past webinars
- An interactive version of your services deck to send after a discovery call
- An internal dashboard built from a data export your team already has permission to use
Each of these is useful on day one, low risk if it isn't perfect, and quick to improve with a follow-up prompt.
Sites or a website builder?
For your main business website, a dedicated builder is still the safer home: it's built for SEO, forms and long-term editing. My comparison of the best free website builders for small business is a good starting point. Use Sites for the quick, useful extras around it.
My verdict: Sites is one of the quickest ways for a non-technical owner to turn a spreadsheet or a pile of documents into something clients can click through. Just remember that deploy means live. If you're new to the model behind it, start with my GPT-6 guide, and if you want help planning what to build, that's what I do in my one-to-one AI sessions.
