This audio may be AI-generated. Always verify important AI answers with trusted sources. World 0 is about removing fear. Before you can use AI confidently, you need four words. First: AI assistant. An AI assistant is a tool that helps answer questions, write, summarize, explain, and organize information. Second: prompt. A prompt is the instruction or question you give to the AI. Third: source. A source is a document, webpage, note, or file that NotebookLM can use to answer questions. Fourth: chat. A chat is the back-and-forth conversation between you and the AI. Here is the key idea: if you can ask a clear question, you can start using AI. A weak prompt is: AI? A better prompt is: Explain what an AI assistant is in plain language for someone who has never used one. Use one everyday example. That better prompt gives the AI a job, an audience, and a format. Your tiny practice task is to write one sentence explaining what a prompt is. A strong answer is: A prompt is the instruction or question I give to an AI assistant. That is enough to earn your first badge.
