Tibo (@thsottiaux), who leads Codex and ChatGPT at OpenAI, quoted a post from the official @OpenAIDevs account at 4:16 a.m. KST on August 21, 2026, telling people to "make a ChatGPT Site, share it, and build something together." He added, "building small games and sites with colleagues is really fun." The post drew more than 410,000 views.
The original OpenAIDevs post that Tibo quoted reads: "You can add teammates as editors on ChatGPT Sites to build and publish together. Collaborators can make changes to the same project, and Codex handles git and CI behind the scenes."
What the official release notes confirm
The same details appear in the Business and Enterprise release notes in the OpenAI Help Center. A Site owner can add members of the same workspace as editors. Editors can modify and save the Site, and after the owner's first publish they can publish later versions to the same Site URL. Owners keep control over sharing scope, Site settings, analytics, ownership, version restore, and editor permissions.
Co-editing uses the existing Sites workspace permission system and adds no separate permission toggle. Public publishing is off by default and controlled by admins.
What is ChatGPT Sites?
ChatGPT Sites lets you describe a website or web app in plain language, after which Codex builds it and OpenAI hosts it. It is used to create things like dashboards, project trackers, internal portals, and prototypes. It is currently offered mainly in ChatGPT Business and Enterprise workspaces.
What this means in practice
Until now, refining an AI-built web app with a team meant downloading the code and handing it to a developer. This update lets non-developer teammates work directly on the same project, which is worth a look for startups and agencies that want to get internal tools or simple dashboards running quickly. Keep in mind, though, that having Codex handle git and CI also means the team has less direct control over its code history.
What still needs confirmation
This collaborative editing feature was confirmed in the Business and Enterprise workspace release notes, and official documentation does not confirm whether it applies equally to individual Plus and Pro users. Companies adopting it should check details such as data processing location and social login policies separately in the workspace admin console.
