ChatGPT Space gives shared pages and files a home, but sharing needs care

OpenAI's Space documentation describes editable pages and files that people can work on together, with each collaborator using their own ChatGPT. Space replaces Library, not Projects. Owners can choose view or edit access and remove collaborators. Files uploaded into a page follow its permissions; linking to an external file does not automatically unlock that file.

For a shared brief, research notes or a project document, the useful change is working on the same material instead of passing separate chat exports around. Each person keeps their own ChatGPT context. That could make collaboration easier, but it is not a free-plan recommendation: OpenAI lists eligible Pro, Business and Enterprise accounts, and managed workspace controls can limit access or sharing.

We checked OpenAI's documentation, not a working Space session. Sharing a page does not expose your private chats or ChatGPT Memory. Information copied or written onto that page is visible to its readers, including personal details an assistant may draw from your context. Each collaborator's own training and Memory settings apply to their interaction. Review page contents and permissions before sharing. This is an October 3 explainer, not a claim that Space launched today.
