OpenAI's ChatGPT Sites turns a description into a live, published web page or app. Here is what it actually does, who gets it, and the gap it still leaves for anyone trying to be found.

OpenAI shipped ChatGPT Sites, a website and web-app builder that lives inside ChatGPT, on July 9, 2026 as part of the ChatGPT Work launch. You describe the site you want in the chat — or tag @Sites in a prompt — and ChatGPT scaffolds it, shows you a private preview, refines it as you give feedback, and publishes it to a live URL when you say go. It is a genuine build process, not a template picker: the model generates a real app, deploys it, and hands back a working address you can share.
Sites is included at no extra cost on paid ChatGPT plans — Plus, Pro, Business, Enterprise, and Edu — and is not offered on the free or Go tiers. The rollout has been staged by plan and region rather than flipped on everywhere at once, and it was not available in every country at launch. There is no separate add-on fee; it is part of the plan you already pay for.
Through the summer and into the fall the feature matured quickly. At OpenAI's DevDay on September 29, 2026, the company said Sites was already hosting roughly eight million sites. Along the way OpenAI added Build Together, which lets several people edit, save, and publish the same site rather than funneling every change through one person; private sharing with named viewers you invite; the ability to rename a site's URL; custom domains, where you connect a domain you already own by adding DNS records (OpenAI does not register domains for you); and backing storage so a site can hold structured data and files. OpenAI also says it cut the time from prompt to deployed site roughly in half.
The honest caveats matter as much as the features. Sites can only be created and managed inside ChatGPT — there is no public API or agent surface to build or update one from outside the app. Beta usage limits apply and have not been published, so a high-traffic site can hit a ceiling you cannot see in advance. And the questions a creator cares about most — whether search engines index these pages well, and whether a published site feeds into ChatGPT's own answers — are not documented; OpenAI has not confirmed either, so you should not assume them.
Think of a ChatGPT Site as the storefront and content as the foot traffic. OpenAI just made the storefront trivial to build — but it did nothing about the traffic, and that is the half most creators are actually stuck on. A published Site sits at its URL whether ten people or ten thousand see it, and the thing that decides which is a consistent flow of posts, video, and email pointing at it. ChatGPT Sites builds the page; it does not clip a video, draft a week of captions, render a carousel, or post anything to a single platform.
That is the exact seam [Kompozy](/) fills. Spin up your Site in ChatGPT, then point Kompozy at one source — a short video, a few notes, an offer — and it fans the idea into finished, on-brand assets: captioned [persona and avatar shorts](/glossary/persona-shorts), brand-exact carousels and quote cards, a [blog article and an email newsletter](/glossary/output-buckets), and platform-native text posts. Put your Site's URL in every bio and CTA, then let [autopilot](/glossary/autopilot) schedule and publish the batch across the eight social platforms plus blog and email through a per-post review gate, each output held to one voice by a [Persona Brief](/glossary/persona-brief). OpenAI gives you the page in minutes; Kompozy is what keeps people arriving at it.
ChatGPT Sites is OpenAI's built-in website and web-app builder. You describe the site you want in ChatGPT (or tag @Sites), and it builds a real app, shows a private preview, refines it from your feedback, and publishes it to a live URL. It launched July 9, 2026 as part of ChatGPT Work.
It is included at no extra charge on paid ChatGPT plans — Plus, Pro, Business, Enterprise, and Edu — and is not available on the free or Go tiers. There is no separate add-on fee. The rollout has been staged by plan and region, and it was not available in every country at launch.
OpenAI has not documented either. Search-indexing behavior is unspecified, renamed URLs use temporary (307) redirects that search engines do not treat as permanent, and OpenAI has not confirmed that published Sites feed into ChatGPT's answers. Do not assume a Site is discoverable the way a well-optimized web page is.
No. Sites builds and hosts a web page or app; it does not generate social posts, video, carousels, blogs, or newsletters, and it publishes to nothing but the site itself. To produce and distribute the content that drives people to your Site, you pair it with a content engine like Kompozy.
