How to Use Projects in ChatGPT

Keep everything about one thing in one place: the chats, the files and the instructions. Tell ChatGPT once, and every new chat in the project already knows.

What a project is, in one minute

A project is a folder in ChatGPT for one thing you're working on: a party, a move, a job search, a small business. It holds the chats about it, the files you add, and instructions you write once. Every new chat you start inside the project already knows them, so you stop explaining the same background again and again.

It works on a free account. On ours (checked 10/22), "Projects" was in the sidebar and a project was ready in a few seconds. OpenAI says Free allows up to 5 files in a project.

On a free account, ChatGPT can't read your Gmail: on ours, the Gmail plugin said "Upgrade to Plus". A project is the free way to keep the details of one thing in one place, and to bring them into every chat about it.

Which way to use

A project is worth it when you'll come back to the same subject more than once. For a one-off question, a normal chat is enough.

Use a project when

  • You keep starting chats about the same thing, and keep retyping the same details.
  • You have a file or two that ChatGPT should look at every time, like a list or a plan.
  • You want your chats about one thing together, not lost in the long list in the sidebar.

Use something else when

  • Teach ChatGPT about you, for every chat: You want every chat, not just one project's, to know your business or how you like answers. That's custom instructions.

    Read the guide
  • Ask about one document, once: You have one file and a few questions about it, and you won't need it again. Attach it to a normal chat.

    Read the guide
A project only knows what you put in it. If a detail changes, like the date or the budget, change it in the instructions or the file, too.

Your first project, step by step

A real example: planning a 70th birthday party for Dad. The party's details go in once, the guest list goes in as a file, and then every chat about the party starts already knowing them. The pictures use ChatGPT on a free account, on a computer. The family and the guest list are made up.

  1. Step 1: Find Projects in the sidebar

    Go to chatgpt.com and sign in; a free account works. In the sidebar on the left, find "Projects". Hold the mouse over it, and click the "+" that shows up at its right.

    The top of ChatGPT's sidebar: New chat, Images, Scheduled, Library, Plugins, Health, Codex, Explore, and under them Projects, with the plus button next to it marked.
  2. Step 2: Give it a name

    A "Create project" window opens. Type a name you'll recognize later. Name it after the thing, not the first question: "Dad's 70th Birthday", not "Food ideas".

    The Create project window with the Project name box marked, holding Dad's 70th Birthday, the note Projects keep chats, files, and custom instructions in one place, and the Create project button.
  3. Step 3: Choose what it remembers

    Click "Default memory" for the two choices. With Default memory, the project can use what ChatGPT remembers from your other chats, and the other way around. With Project-only memory, it uses only its own chats and files, and keeps them out of the rest. We picked Project-only, so nothing from other chats mixes in. Then click "Create project". You can change this later in the project's settings.

    The memory menu open under the Create project window: Default memory, This project can access memory from outside chats, and vice versa, and Project-only memory, This project can only access its own memory, marked.
  4. Step 4: Meet the project's page

    The project opens on its own page. At the top is its own message box, "New chat in" and the project's name: a chat started here lives in the project. Under it, "Chats" lists the project's chats, and "Sources" holds its files. The project also shows in the sidebar, under Projects.

    The empty project page: Dad's 70th Birthday with Share and a three-dot button, the message box New chat in Dad's 70th Birthday marked, the Chats and Sources tabs, and No chats yet.
  5. Step 5: Write the instructions once

    Click the three dots at the top right, then "Project settings". In "Instructions", write what every chat should know: the facts, and how you want answers. Click "Save". OpenAI says these instructions apply only inside the project, and there they take the place of your general custom instructions.

    The Project settings window with the Instructions box marked: the party is Saturday, June 12, 2027, 2 to 6 PM, in our backyard, a budget of $800, Dad loves jazz and grilled food, the guest list is in the project's files. Under it, Memory Project-only, Library access Disabled, Delete project, Cancel and Save.

    Try this prompt

    This project is for [what it's about]: [the date, the place, the key facts]. The budget is [amount]. [Anything ChatGPT should keep in mind.] Keep answers short and practical.
  6. Step 6: Add a file to Sources

    Click "Sources", then "Add sources". A window opens: drag a file in, or click "Upload" and pick it. "Paste text" works too, if what you have is in an email or a note. Use "Add sources" on the project page, not the "+" in the message box: when our file went in through the message box, the project didn't keep it.

    The Add sources window: a Drag sources here area, and under it Upload, marked, Paste text and Slack.
  7. Step 7: Check the file is there

    The file shows in the Sources list, with the day you added it. Ours was the guest list, a small spreadsheet: who's coming, adults and kids, and a food note. Click a file in the list to look at it, download it or delete it.

    The project's Sources tab with Add sources, and party-guest-list.csv, File, Oct 22 marked in the list.
  8. Step 8: Ask without explaining

    Click the project's own message box and ask, as if ChatGPT already knew the whole story, because now it does. Don't repeat the date, the budget or the guests. Press Enter.

    The project page with the message box marked, holding Make a shopping list for the party food, with amounts.

    Try this prompt

    Make a shopping list for the party food, with amounts.
  9. Step 9: See it use the details

    The answer used everything in the project. From the instructions: Frank, the backyard, grilled food, jazz and the $800 budget. From the file: 20 confirmed guests and 2 maybes, 6 of them kids, the vegetarian guests and Linda's gluten-free buns. We checked the counts against the list, and they were right. Still check numbers yourself before you shop.

    ChatGPT's answer to the shopping list request: a backyard BBQ for 20 confirmed guests with food for 2 maybes, within the $800 budget, a menu that works for the vegetarian guests and Linda's gluten-free needs, amounts for about 22 people including 6 kids, and the start of the list: burger patties, hot dogs, chicken thighs, veggie patties, buns, gluten-free buns, cheese.
  10. Step 10: Find the chat in the project

    Click the project's name in the sidebar, or go back to its page. Under "Chats" is the new chat, with the name ChatGPT gave it and your first message under the name. Every chat in the project lands here.

    The project page with one chat in the Chats list, marked: Party Shopping List, Make a shopping list for the party food, with amounts.
  11. Step 11: Start a second chat

    From the project's page, start another chat about something else. It starts with the same instructions and files. Our second chat asked only for an invitation, and the text had the date, the hours, the backyard, the grill and the jazz in it.

    A second chat in the project: Write a short invitation text I can send to the guests, and ChatGPT's invitation: Dad's 70th birthday on Saturday, June 12, 2027, from 2 to 6 PM in our backyard, food off the grill and a little jazz.

    Try this prompt

    Write a short invitation text I can send to the guests.
  12. Step 12: Move an old chat in

    A chat you started before the project can join it. In the sidebar, hold the mouse over the chat, click its three dots, then "Move to project", then the project's name. We moved in a chat about a toast for Dad. OpenAI says a moved chat gets the project's instructions and files from then on.

    A chat's menu in the sidebar: Rename, Pin, Share, Archive, Delete and Move to project, with its list open: New project, and Dad's 70th Birthday, marked.
  13. Step 13: Delete a project you're done with

    When it's over, click the three dots on the project's page, then "Project settings", then "Delete project" at the bottom.

    The Project settings window with Delete project marked under the Instructions, Memory and Library access settings.
  14. Step 14: Confirm, and know what goes

    ChatGPT asks once more, and says what goes: the project and all its chats and files, for good. To keep a chat, move it out before you delete: its three dots in the sidebar, then "Remove from project". Then click "Delete from Chat and Work".

    The window Delete this project from Chat and Work?, saying it will permanently delete the project, including all its chats and files, and that this cannot be undone, with Delete from Chat and Work marked next to Cancel.
