Ultra Power / Guides / Delete your history

How to delete your ChatGPT history

There are three routes, and ChatGPT only ships two of them. One chat at a time, from the menu on the row in your sidebar. Everything at once, from Settings, then Data controls, then Delete all chats. Or in batches, which needs an extension because ChatGPT has no multi-select. All three are permanent: nothing you delete in ChatGPT can be undone, by you or by support.

One chat

Hover the chat in the sidebar, open the menu on the row, choose Delete, confirm. It is gone in that second. Fine for one. For forty it is forty menus and forty confirmations, which is why most people never actually do the clean-up they keep meaning to do.

All of it

1. 1
   Profile menu, Settings

   The avatar at the bottom of the sidebar, or the same avatar in the mobile app.

2. 2
   Data controls

   This tab holds shared links, archived chats, Archive all chats, Delete all chats and Export data. Path checked on 9 September 2026.

3. 3
   Delete all chats

   Confirm, and your history is cleared. There is no recycle bin behind it and no undo. Treat this button the way you would treat formatting a drive.

The bit in the middle: a few hundred, but not everything

This is the case ChatGPT has no answer for. You want the 300 throwaway chats gone and the twenty that matter kept, and the site gives you a choice between one-at-a-time and all-of-it.

1. 1
   Tick, or select all

   Ultra Power puts a checkbox on every chat. Shift-click takes a range. Select all reaches every chat in your history, not only the ones the sidebar has drawn, because the extension keeps its own local index.

2. 2
   Read before you commit

   Click into any chat to check what it is and untick it. The selection is held by the extension, so it survives previewing, navigating and a full reload.

3. 3
   Move to trash

   They leave your list immediately and stay restorable for 12 hours, or 7 days on Pro. Delete now in the trash skips the window when you want something gone straight away.

About three seconds per chat is ChatGPT's own API speed, and the extension runs a batch of them in parallel, so a couple of hundred takes roughly a minute while you get on with something else. Free covers 25 chats per action, which is a real cap rather than a trial: 300 chats is twelve actions, or one on Pro.

Three things people expect deleting to do, and it does not

• It does not clear what ChatGPT remembers about you. Saved memories are a separate list under Personalization, and they survive every chat you delete. If your goal is that ChatGPT stops knowing something, delete the memory, not the conversation.
• It does not switch off training. That is its own toggle in Data controls ("Improve the model for everyone"). Deleting chats after the fact is not the same as never having contributed them.
• It does not make the data instantly non-existent. OpenAI's documentation says deleted conversations are removed from their systems within 30 days, apart from copies kept for security or legal reasons, and there has been active litigation about exactly those copies. The longer answer is here.

On iPhone and Android

The same account, so the same history and the same routes: delete a single chat from its own menu in the app, and the app's settings carry the same Data controls. Deleting on your phone deletes everywhere, immediately, and there is no separate phone-only copy to clear. Bulk selection is a browser thing: extensions do not run in the mobile apps, so a big clean-up is a desktop job.

Not creating history in the first place

ChatGPT has a temporary chat mode that keeps a conversation out of your history entirely. For the one-off question you would delete afterwards anyway, that is less work than deleting it, and it never shows up in your sidebar to be cleaned up later.
