If you are a heavy ChatGPT user and use it to write content, solve problems, answer questions or pretty much anything else, there's a feature that can make conversations more personalised by remembering details from previous interactions. But! It can also cause major issues for certain types of content requests, since it will draw from those previous conversations, contaminating new content with stuff that shouldn't be in it. So follow along as we show you how to fix this issue.

How to Stop ChatGPT From Using Old Conversation Chat History
There are several things you can change to stop ChatGPT from storing and using information from previous conversations.
- Open ChatGPT and click your profile icon to open the main menu.
- Select Settings, then open the Personalisation section.

- Scroll down until you find the Memory settings.
- Turn off the option that allows ChatGPT to use or save memories.

Disabling memory prevents ChatGPT from saving new details for use in future conversations. Disabling this feature does not necessarily remove memories that were already saved, so they can still contaminate any future requests.
Delete Saved Memories
After turning off memory, check the Manage memories or Memory section, depending on the version of ChatGPT you are using. Here, you will find information that ChatGPT has saved from previous conversations. There will be a ton of random stuff stored here, and depending on how long you've been using the feature might be a lot!
- Delete the saved memories if you do not want them to remain available for personalisation.
- If ChatGPT has an option to delete all saved memories while turning off memory, use that option. (It's not always available)
You can also check any information listed in personalisation fields, such as details you have explicitly provided about yourself, and remove anything you no longer want saved.

Delete Your Previous Chats
Turning off memory does not automatically delete your existing conversations. If you want to remove your old chat history as well, you need to do that separately.
- Go back to Settings and open Data Controls.
- Look for the option to delete your chats.
- If you want to remove your entire conversation history, select Delete all chats and confirm the action.
If you have conversations you may need later, think about exporting your ChatGPT data before deleting anything. This gives you a copy of your information without keeping the conversations in your ChatGPT history. It will let you keep a local copy for future reference.
Why Deleting Old Chat Data is Important
Disabling memory and deleting saved memories can stop ChatGPT from using those saved details for personalisation, but your existing conversations are a separate part of your account history.
If you leave old conversations in your account, they can remain available in your chat history. Depending on your settings and the features available to your account, ChatGPT may also use past conversations as context for future responses. If you want consistent, regular results, it's best to purge things quite regularly and leave memory off.
