GPTs vs Projects
A custom GPT is a shareable assistant you publish for others; a Project is a personal workspace for your own ongoing work.
Same ingredients, very different purposes
Both custom GPTs and Projects let you bundle instructions and files with a version of ChatGPT. From the outside they look similar, but they are built for completely different situations.
A custom GPT is a shareable assistant. You configure it, give it a name, and publish it. Others can open your GPT and start chatting right away, without writing any instructions themselves. The instructions and files you set are baked in for everyone who uses it. Creating and publishing custom GPTs may not be available on all ChatGPT plans, the option may vary depending on which version you are using.
A Project is a personal workspace. You create it to organize your own ongoing work, group related chats, share a consistent set of instructions and files across those chats, and keep everything in one place. A Project is for you, not for publishing to others.
| Custom GPT | Project | |
|---|---|---|
| Sharing | Can be published for others to find and use | Private to you, not shareable |
| Personal organization | Not designed as a personal workspace | Groups your related chats in one place |
| Files | Baked in for all users of the GPT | Your own files, available to your chats |
| Who it is for | Building a helper others will use | Organizing your own ongoing work |
Custom GPT or Project?
Answer two questions about what you're building and get a recommendation, grounded in the same distinctions from the comparison above.
Do other people need to open this and use it themselves?
Is this for organizing your own ongoing chats, privately, with shared instructions and files?
Answer both questions to see your recommendation.
Three scenarios to help you pick the right tool.
It is just for you
If you want a consistent setup for your own ongoing work, a writing project, a research effort, a client engagement, use a Project. It organizes your chats, applies shared instructions, and keeps your files in one place, all privately.
You are sharing a helper with others
If you want to create something others can use, an onboarding assistant for your team, a tool for clients, or a publicly available GPT, build a custom GPT. You configure it once; everyone who opens it gets the same experience, no setup required on their end.
It is a quick one-off task
If it is a single task that does not belong in a project and you do not need to share anything, a plain chat with your global custom instructions already set is usually enough. Start a new chat, send your request, and move on.
Question 1 of 4
A marketing manager wants to create a writing assistant for her ten-person team. Each teammate should be able to open it and get help with campaign copy in the company's brand voice. Which tool fits?
