To create a new chat in ChatGPT, look for the option that starts a fresh conversation, usually labeled New chat or something similar in the interface. On the web version, this is often in the sidebar or near the top of the page. In the mobile app, it is commonly available from the main screen or through a plus icon or menu button.
Starting a new chat creates a separate conversation thread, so the new exchange does not continue the context from the previous one. That can be helpful when you want to change topics, begin a new task, or avoid earlier context affecting the response.
If the interface looks different from what you expect, the current web page may have help or account information that explains the exact layout for that version. If the option is still not visible, refreshing the page or checking whether you are signed in can also help.
