Can you share a ChatGPT project with someone?

Blog · Published 2 September 2026 · Updated 30 September 2026

Yes. Every ChatGPT plan can share a project, from Free to Enterprise. You invite people by email, by group (on Business, Enterprise and Edu) or with a link, and give each person chat or edit access. They see the project’s chats, files and instructions, and ChatGPT answers from all of it through the project’s own memory. Everyone who joins needs a ChatGPT account, so a colleague who works in Claude can only take part by signing in to ChatGPT.

Which ChatGPT plans can share a project?

All of them: Free, Go, Plus, Pro, Business, Enterprise and Edu, on the web and in the mobile apps. What changes by plan is how many files a project holds and how many people can join, and the owner’s plan sets the number of collaborators.

Plan Files per project Collaborators per project
Free 5 5
Go, Plus 25 10
Pro 40 100
Business, Enterprise, Edu 40 Up to 100

You can upload 10 files at a time. On Business, Enterprise and Edu, workspace owners decide who can create and share projects, and invitations may be limited to members of the workspace. ChatGPT Business was called ChatGPT Team until August 2025, so older guides use that name.

How do you share a ChatGPT project?

  1. Open the project and select Share.
  2. Invite people by name or email. On Free, Go, Plus and Pro you invite individuals; on Business, Enterprise and Edu you can also invite a workspace group, or share a workspace link that anyone in the workspace can use to join.
  3. Give each person Chat or Edit access.
  4. Select Invite. You and each person you invited get a confirmation email.

On Free, Go, Plus and Pro, the owner can also set the link to “Anyone with a link”. Then anyone signed in to ChatGPT who has the link can join, up to the owner’s plan limit, and the owner can switch back to invite-only at any time.

The owner can change anyone’s access or remove them whenever they like, even before they have joined. People with edit access can invite others but can’t remove anyone.

What does the other person see?

Everything in the project: its chats, its files, its instructions and its member list. Each chat shows the profile icon of the person who started it, and every member can view and download the project’s files.

What they can do Chat access Edit access Owner
See and use the chats, files and instructions Yes Yes Yes
Start new chats and branch existing ones Yes Yes Yes
Change instructions, add or remove files No Yes Yes
Invite people No Yes Yes
Remove people, rename or delete the project No No Yes

To build on a teammate’s chat, you branch it: the conversation continues in a new chat, and the original stays as it was, visible to everyone in the project. Two people can’t type in the same chat at the same time.

If you share a single chat from a shared project by link, the person you send it to can’t open it until they join the project.

Do shared ChatGPT projects share memory?

Yes, inside the project. A shared project is set to project-only memory automatically, and it can’t be switched back. In practice:

  • ChatGPT can reference other chats in the project, including the ones your colleagues started.
  • It does not use any member’s saved memories, custom instructions or chats from outside the project.
  • Chats outside the project can’t reference chats inside it.
  • There is no list of project memories to review. To stop ChatGPT drawing on a chat, delete it, or move it to another project where the settings allow.

Referencing other chats needs memory turned on in your own settings and, on Business, Enterprise and Edu, allowed by the workspace. Each member’s own memory, the one ChatGPT keeps across their other chats, stays theirs.

What are the limits of a shared ChatGPT project?

  • Everyone works in ChatGPT. Only people signed in to ChatGPT can join, and the project lives in the owner’s account or workspace.
  • Plans set the size. Files and collaborators follow the table above, and the owner’s plan sets how many people can join.
  • Deleting is final for everyone. If the owner deletes the project, its chats, its instructions and the files stored only in it are gone for every member, and it can’t be undone. A member who leaves can first copy their own chats into a new project.
  • On Business, Enterprise and Edu, workspace owners decide. They can turn sharing off, limit who creates and shares projects, and remove people from a project at any time.
  • Training follows everyone’s settings. On personal accounts (Free, Go, Plus and Pro), shared project data may be used to improve models only when the owner and every contributor have “Improve the model for everyone” turned on. OpenAI does not train on Business, Enterprise or Edu data by default.

What if someone on the project uses Claude?

This is where a shared ChatGPT project stops. Your colleague on Claude can join with a ChatGPT account, even a free one, but then they are working in ChatGPT, and the Claude they use every day never sees the project. Claude has project sharing of its own on its Team and Enterprise plans, and it reaches only people in the same Claude organisation.

So a team split across AIs has two options. One is two copies, a project in each app, with someone carrying every change across by hand. The other is a project that lives outside both apps, which each person opens from their own AI; sharing a ChatGPT project with Claude walks through both, including which ChatGPT plans can open an outside project through MCP.

Where does Alcoven fit?

If everyone on the project uses ChatGPT, a shared project may be all you need. When the team is split across AIs, Alcoven keeps the project in one place outside both apps: the brief, documents, tasks and history, shared by the people and agents on it. Add the project’s link, which looks like https://app.alcoven.co/mcp/your-project, to Claude, or to ChatGPT on a plan where an MCP tool can write. Clone it with git to work from Claude Code or Codex. Or ask the project in the Alcoven app. Whatever your AI changes comes back under your name, for everyone on the project, and every document keeps every past version. You choose who is on it, each person or agent allowed to read, write or manage, and nothing is public. Free covers one project and up to five people writing to it, with no card. Start a project free
