OpenAI's build-a-website-from-a-prompt tool inside ChatGPT — describe a site or web app in the chat and it scaffolds, previews, and publishes it to a live URL.

ChatGPT Sites is a website and web-app builder that lives inside ChatGPT. You describe what you want in the chat — or tag @Sites — and it scaffolds a real, working app, shows you a private preview, refines it as you give feedback, and publishes it to a live URL when you are ready. It is a genuine build-and-deploy process rather than a template picker, and updates publish in place at the same address with a save-then-deploy review step.
It launched on July 9, 2026 as part of the ChatGPT Work release and is included at no extra cost on paid ChatGPT plans — Plus, Pro, Business, Enterprise, and Edu. It is not offered on the free or Go tiers, and the rollout has been staged by plan and region. By OpenAI's DevDay on September 29, 2026, the company said Sites was already hosting roughly eight million sites.
Over the summer it gained Build Together (several people editing, saving, and publishing one site), private sharing with named invited viewers, URL renaming, custom domains connected via DNS for a domain you already own, and backing storage so a site can hold structured data and files. OpenAI also cut deploy time roughly in half.
Know the edges before you lean on it. Sites can only be created and managed inside ChatGPT — there is no public API or agent surface. Beta usage limits apply but are not published. And the two things a creator cares about most — whether these pages index well in search, and whether they surface in ChatGPT's own answers — are undocumented, so do not assume either.
The most useful way to pair ChatGPT Sites with a content workflow is to treat the Site as your hub and Kompozy as the feed that keeps it alive. A page built in minutes is only as valuable as the number of people who reach it, and the thing that reliably sends people to a hub is a steady drumbeat of platform-native content that links back to it. ChatGPT Sites builds the hub beautifully and then goes quiet — it makes no posts, no video, no carousels, no email — so the hub sits there waiting for traffic it cannot generate.
[Kompozy](/) is the always-on content calendar for that hub. Point it at one source — a short video, a few notes, a new offer on your Site — and it fans the idea into a full batch: captioned [persona and avatar shorts](/glossary/persona-shorts) and HeyGen video, [Clipped Shorts](/glossary/clipped-short) from long-form footage, brand-exact carousels and quote cards, and a [blog article plus an email newsletter](/glossary/output-buckets) that both link to the page. A [Persona Brief](/glossary/persona-brief) keeps every output in one voice, and [autopilot](/glossary/autopilot) schedules and publishes the batch across the eight social platforms plus blog and email through a per-post review gate — with your Site's URL as the destination in every bio and CTA. Kompozy runs Claude and OpenAI for its own generation; it does not build or host the Site. ChatGPT makes the page; Kompozy fills the top of the funnel that feeds it.

OpenAI has not documented either. Search-indexing behavior is unspecified, renamed URLs use temporary (307) redirects, and in-answer surfacing is unconfirmed. If organic discovery matters, do not assume a ChatGPT Site behaves like a well-optimized page on a mature builder.
No. Sites builds and hosts the page only; it creates no social posts, video, carousels, blogs, or newsletters. To produce and publish the content that sends people to your Site, pair it with a content engine like Kompozy, which generates and distributes content across platforms.
