Google NotebookLM（Google 帮助中心目前称为 Gemini Notebook）是一款围绕你提供的资料工作的 AI 研究助手：把某个项目的文件和链接放进一个 notebook，再在 Chat 中提问，并用 Studio 将来源整理成学习指南、简报、音频概览或思维导图。它适合分析自己的材料，不应当被当作能够任意检索所有网络信息的通用搜索引擎。
NotebookLM 能做什么？
一个 notebook 是一个项目的资料集合。你添加来源后，可以在 Chat 中针对这些材料提问；回答通常带有指向来源内容的行内引用，方便回到原文核对。NotebookLM 可能出错，Google 也提醒答案不代表 Google 的观点，因此引用应当作为核查入口，而不是准确性的保证。Google 帮助：了解 Gemini Notebook
NotebookLM 也可以把来源整理成学习指南、简报、音频概览和思维导图等形式。它的价值在于帮助你阅读、归纳和重组已经收集的资料，而不是替你判断资料是否真实、完整或最新。
如何开始使用 NotebookLM
- 登录并打开服务。使用 Google 账户打开 NotebookLM；工作或学校账户可能需要管理员启用相应服务。
- 为一项任务新建 notebook。例如建立“论文综述：城市热岛”或“产品调研：便携显示器”。不同 notebook 相互独立，NotebookLM 不会同时读取多个 notebook 的资料，所以把同一项目的材料放在一起，并将无关项目分开。Google 帮助：创建和管理 notebook
- 添加来源。可从文件、Google Drive 文档或网页、公开视频等导入材料；下文列出常见格式和重要限制。导入前确认你有权使用这些内容。Google 帮助：添加或发现来源
- 等待处理完成，再在 Chat 提问。问题要指出任务和需要的输出。例如：“列出这份报告对成本上升的三个解释，并为每点给出来源引用。”如果 notebook 来源较多，可在问题中点明来源名称，或先选定要使用的来源子集。
- 核对引用并整理结果。点击 Chat 回答中的引用，检查对应原文，再把确认过的摘要、时间线或其他结果用于自己的笔记或 Studio 输出。
可以导入哪些资料？
Google 的帮助页面列出的来源类别包括 PDF、Word 和其他 Office 文件、文本与 Markdown、Google Docs、Slides 和 Sheets、图片、CSV、音频、网页 URL、YouTube URL、ePub、符合条件的 Play Books 电子书，以及 Gemini 对话等。具体格式、文件限制和可用功能可能随账户、设备及产品更新变化；导入前可查阅Google 当前的来源导入说明。

网页：只抓取指定页面的文本

YouTube：依赖视频字幕

Google Drive：需要持续的查看权限
Drive 来源需要相应访问权限，并可自动同步。同步不会赋予 NotebookLM 编辑原文件的能力；如果原文件被删除，或你不再拥有查看权限，该来源可能无法继续使用。
怎样让回答更有用、更容易核查？
- 问具体任务，而不是只要泛泛总结。说明要找的主题、数量、范围和输出格式，例如“按时间顺序列出报告提出的政策变化，并引用每项对应的来源段落”。
- 缩小资料范围。针对特定文件提问时，选择对应来源；来源多时在问题里写出文件名称，降低答案混入无关材料的可能。
- 把引用当作核查线索。逐项打开引用，确认它确实支持答案中的说法；来源没有答案、问题含糊或安全过滤都可能造成无法回答或检索效果不佳。
- 区分原文与生成内容。摘要、学习材料或音频概览是对来源的处理结果，不是来源本身。用于报告、教学或决策之前，回到原始资料检查关键事实和上下文。
Studio 和 Audio Overview 怎么用？
Studio 可将 notebook 来源转成多种学习或整理材料，包括学习指南、简报、音频概览和思维导图。音频概览是 AI 生成的音频内容，并不等同于由真人采访、编辑和制作的播客。Google 的帮助页面列出 Deep Dive、Brief、Critique 和 Debate 等音频形式，并说明可使用语言、长度及自定义提示等控制；界面选项可能因账户或版本而异。Google 帮助：创建音频概览

生成的内容可能不准确，音频也可能发生故障。把音频用于学习或分享前，应回查原材料中的名称、数字和关键结论。分享音频时还要考虑 notebook 的访问权限和来源版权；是否能下载或通过链接分享，取决于具体功能和账户情形，不能假定所有 notebook 都能公开传播。
分享 notebook 前要检查什么？
Google 的分享说明区分 Reader 和 Editor：Reader 可以查看共享的来源和笔记；Editor 可以修改来源、笔记并继续分享。Chat-only 视图会隐藏材料，提供较简洁的界面，但不必然撤销对底层内容的访问。分享前应核实对象、角色和内容权限，并避免把不应公开的资料放进可分享的 notebook。Google 帮助：创建和管理 notebook
