Quick chat is great if you want help with a simple task like translating a text, doing a quick search, summarizing information or similar types of tasks where you don't need the complexity of your Agents in Multiply.
Head over to Chats in the left navbar and create a new chat by just typing into the prompt box.
You will find a list of your previous chats at the top if you ever want to go back to a previous conversation. Note that it's currently not possible to delete or archive old chats.
