As a language model trained to assist with various tasks and provide information, ChatGPT keeps a record of your conversations. From the first conversation to the last, all of those are stored on the left panel so that anytime you want to refer to your previous conversations, you can still access them. However, there may come a time when you want to clear your chat history for privacy or organizational reasons. Here are the steps to delete ChatGPT conversation history:
1. Open ChatGPT and sign in with your Login ID and password.

In conclusion, deleting ChatGPT conversation history is a straightforward process that can help you maintain your privacy and organization.
