What ChatGPT Projects is
A ChatGPT Project keeps related chats, files and instructions together, so every chat in it starts from the same context. You can share a project, and the people you invite see its chats and files and start chats of their own.
- What it holds
- Chats, uploaded files, project instructions, and links to Google Drive files and Slack channels. Free allows 5 files a project, Plus and Go 25, and Pro and Business 40.
- Sharing
- By invitation or by link, with chat or edit access. Up to 100 people on Pro, 10 on Plus and Go, 5 on Free.
- Memory
- A shared project uses project-only memory. It can't see a member's memories or instructions from outside the project.
- Working together
- Members start their own chats, or branch a teammate's to build on it.
For work that stays in ChatGPT, a shared project is enough, and cheap to start. A teammate on a free plan can join, read the whole project and branch your chat where you stopped. The limit is the edge of ChatGPT: OpenAI's page describes a project as a place inside ChatGPT, and describes no way for Claude, Grok or Cursor to open one.
