Bug in ChatGPT "Incognito" mode

Yesterday I spent a lot of time comparing fatality rate from all sorts of “weird things” to compare against AI fatality rates. I had it compare AI fatalities towards “hamster murders”, “autoerotic asphyxiation”, etc

Today I started an incognito chat, and it obviously has access to our convo from yesterday …

Hence, obviously “incognito mode” doesn’t actually work …

Good question.

See the August 27, 2026 ChatGPT change.

Note: ChatGPT mentioned in a conversation that what was previously referred to as “Incognito mode” is now called “Temporary Chat.”

More controls in temporary chat

We’re rolling out new controls in temporary chat. You can now choose to personalize responses in a temporary chat with memory, plugins, and custom instructions from your regular chat settings. You can also choose to save a temporary chat.

How it works

  • Personalized: When you create a temporary chat, you can choose to have personalized responses. Personalized temporary chats can use your memories, custom instructions, and plugins to tailor responses. They do not create new memories and remain out of your chat history unless you save them. Personalization can be set only when you start a temporary chat and cannot be changed after the conversation begins.

  • Non-personalized: By default, temporary chats are not personalized. Non-personalized temporary chats do not use memory, custom instructions, or plugins, and they do not create new memories.

  • Saving a temporary chat: When a conversation becomes useful for the future, you can add it to your chat history. Saving converts it into a regular chat, so it then follows your account-level personalization settings and model-improvement preferences. For example, if you have memory enabled and save a temporary chat, this will become part of your chat history and can be referenced to personalized future responses.

HTH


With generative AI products changing so rapidly, one has to continually adapt to changes in features, terminology, and behavior.

I am not seeing the option to save a temporary chat anymore in the web version (I do see it on mobile) . is this a bug?

Hey @Kandles,

Saving a Temporary Chat is supported, as explained in our Temporary Chat guide.

If the option is still missing, try a new Temporary Chat in another browser or a private window with extensions disabled. Copy anything you want to keep before refreshing or closing your current chat.

If it continues, please contact Support through the chat bubble at help.openai.com.
