How to use temporary chat in ChatGPT on Mac: steps for the desktop app

What temporary chat is and when to use it

Temporary Chat is a mode in the ChatGPT Mac app. You turn it on, then ask your questions the way you normally would. It suits quick questions you would rather not keep in your regular list of chats. It is not a promise of privacy. The sources checked for this page do not spell out what OpenAI stores, so treat that as an open question, not a guarantee.

A good first use is a one-off task. Say you need a shorter version of a message that mentions a coworker and a project. Open a temporary chat, paste the draft, ask for a tighter version, and copy the result. You do not have to file that draft under a project or pin it later.

Temporary Chat is a poor fit for work you plan to return to. If you need the answer next week, a normal chat is easier to find. You can copy the key points into a note as well. Use the mode for questions you would close the window on anyway.

Temporary chat requirements for Mac

The ChatGPT Mac app needs macOS 14 and an Apple silicon chip. The Mac Install Guide lists M1, M2, and M3 as the chips the app needs. An Intel Mac does not meet that requirement, so these steps will not match what you see there. To check your chip, open the Apple menu, then About This Mac.

Open the desktop app before you try any of this. The web version may show different controls, so the title bar and File menu steps here do not carry over to it. Sign in if the app asks you to. Update the app first if the menus look different from the ones described here.

Turn on temporary chat from the title bar

This is the route most people use. Look at the top of the ChatGPT window, where the model name sits. Click it and a menu opens. Find the Temporary Chat toggle in that menu and switch it on. The chat you work in after that is a temporary one.

Check the toggle state before you type. If you already have a conversation open, the safest move is to start a new chat with the toggle on. Do not paste sensitive text into a chat you opened before you turned the mode on. Check first, then type.

Start temporary chat from the File menu

The File menu gives you the same mode from the menu bar. Click the ChatGPT window so the app is active. Then click File at the top of the screen. Scan the items for one that says Temporary, and choose it. Labels can change between app versions, so read the menu you see rather than trusting a guide's exact wording.

The menu bar belongs to whichever app is active. If you are in Finder or Safari, File shows that app's items, not ChatGPT's. Click the ChatGPT window first, then open File. This trips people up often, so check the window title before you go looking for the item.

Check that temporary chat is on

• Open the model menu from the title bar and read the Temporary Chat toggle.
• Send a short test prompt in the new chat and read the reply.
• After the session, look at your sidebar to see whether the chat appears there.
• Write down the label you saw, so the next visit takes less time.

The sidebar check tells you the most, but it is a test, not a promise. The sources here do not say how temporary chats appear in history. Run the check once, note what your app shows, and use that as your baseline for later sessions.

Switch back to a normal chat

To go back to a normal chat, start a new chat with the toggle off. Check the model menu before you type. If the toggle is still on, switch it off or start over. Keep one habit: read the mode before each sensitive question, not only the first one of the day.

Temporary Chat is not a clean-up tool for old conversations. The sources here do not say it touches past chats at all, so do not count on it for that. To remove chats you already have, follow the steps on the delete page linked below. That is a separate task.

What temporary chat does not promise

This page could not reach OpenAI's help pages, so retention, model training, sync across devices, and plan limits are not verified here. Treat any claim you read in a third-party guide with care, this one included. Check OpenAI's help center for the current wording before you make a decision that depends on it.

Data Controls is a separate setting. The steps for chat history live there, and the linked guide covers them along with their limits. Do not mix the two up. The sources checked here do not show that turning on Temporary Chat changes Data Controls.

Temporary Chat is not a reason to share sensitive data. Do not paste passwords, card numbers, or private medical details into any chat because you think a mode hides them. The mode does not change what you send. Use the same caution you would use with any cloud tool.

Worked examples you can try today

Say you have a lease clause you do not understand. Open a temporary chat, paste the clause, and ask for a plain-language version. Then ask what to check before you sign. Read the answer closely, and take the clause to a lawyer if the stakes are high. The chat is a reading aid, not a legal opinion.

Say you want gift ideas for a friend who likes running. Start a temporary chat, list the friend's interests in plain words, and ask for a short list of ideas. Keep the list in the chat if you like it, or copy the best options into a note before you close the window.

Say you need a quick check on the tax on a receipt. Type the figures in plain words in a temporary chat, and ask the app to show its working. Check that working yourself before you rely on the answer. Math in chat tools can be wrong, so the working matters more than the final line.

A few mistakes show up often. The first is forgetting the toggle is on, which leaves you thinking a normal chat is temporary. The second is assuming a chat you opened before turning the mode on is covered. The third is treating a one-off chat as a safe place for sensitive data.

What this guide checked and what it did not

The steps come from two third-party guides, iGeeksBlog and the Mac Install Guide. OpenAI's own help pages could not be reached when checked, so the menu labels here are the ones those guides describe. Your version may label things differently. Compare the title bar and File menu with what you see before you rely on them.

No keyboard shortcut is verified for Temporary Chat. Some third-party sites list ⇧⌘N for a new chat. Test it yourself and watch the File menu for a shortcut shown next to the item. If the shortcut does not match, use the menu steps instead.
