NotebookLM（Google 帮助中心当前称为 Gemini Notebook）是一个围绕你提供的资料工作的 AI 研究助手。你可以把一个项目的文件和链接放进独立笔记本，在 Chat 中询问这些材料，再用 Studio 将内容整理成学习指南、简报、思维导图或 AI 音频概览。它适合梳理已有资料，不应当被当作能替代来源核查的通用搜索引擎。
NotebookLM 是什么？
NotebookLM 是 Google 的资料研究与整理工具。每个 notebook（笔记本）围绕一个项目收集来源；你可以针对这些来源提问，并把答案或生成的学习材料用于后续工作。Google 将当前产品称为 Gemini Notebook，但 NotebookLM 仍是常见名称。
关键在于它以你添加的来源为工作基础。Chat 的回答旨在从所选材料中提取信息，并提供指向来源内容的行内引用。来源里没有答案、问题不够明确，或系统未能检索到相关内容时，回答可能不完整或无法生成。Google 也提醒产品可能出错；点击引用并核对原文，再使用重要结论。Google 帮助：了解 Gemini Notebook
NotebookLM 可以做什么？
- 提问与归纳：对报告、课程材料或项目文件提出具体问题，整理摘要、解释和引用线索。
- 制作学习材料：使用 Studio 将来源转成学习指南、简报、思维导图等内容。
- 生成 Audio Overview：把来源转成 AI 生成的音频概览。它不是由人工主持或制作的传统播客，内容和音频都可能出错。
- 协作查看资料：分享 notebook，让他人按权限查看或编辑来源和笔记。
如何开始使用 NotebookLM
- 登录并打开工具。使用 Google 账户访问 Gemini Notebook/NotebookLM。工作或学校账户是否能使用，可能取决于组织许可和管理员是否启用。
- 为一个具体任务新建 notebook。例如“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；把无关项目分开，能让提问和检索更聚焦。Google 帮助：创建和管理笔记本
- 添加来源。可从文件、Google Drive、网页或公开视频等来源开始。当前支持的类别还包括文档、表格、演示文稿、图片、音频、电子书等；支持的格式、大小限制和可用功能可能随账户或设备变化，导入前查看Google 的来源导入说明。
- 等待处理，再提出具体问题。与其只问“总结一下”，不如问“列出报告对成本上升的三个解释，并为每点提供来源引用”。笔记本来源较多时，可以在问题中写出来源名称，或先选择要使用的来源子集。
- 核对引用并整理输出。点击 Chat 回答中的引用，确认它支持对应说法。需要学习材料或音频时，在 Studio 中选择适合的输出，再回查原始来源后使用。
- 分享前检查权限。确认分享对象、来源权限和内容的使用权。Reader 可以查看已分享的来源和笔记；Editor 可以修改来源与笔记并继续分享。Chat-only 视图会隐藏材料以提供较简洁的界面，但这不一定会撤销对底层内容的访问。Google 帮助：笔记本分享与权限
哪些来源可以导入？导入后有什么限制？
Google 的导入说明涵盖 PDF、Word、文本和 Markdown、Google Docs/Slides/Sheets、图片、Office 文件、CSV、网页 URL、YouTube URL、音频、ePub、合资格的 Play Books 电子书及 Gemini 对话等来源类型。具体格式与限制会变化，且某些功能可能因账户、平台或文件格式而不可用；不要假定导入就等于完整复制了原网页或视频。

Elebase USB to USB C Adapter for iPhone 18 Pro Max,USBC Car Charger Adapter
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- 网页：网页来源只抓取指定 HTML 页面的文本；图片、嵌入视频和嵌套网页不会一并导入，付费墙内容不受支持。
- YouTube：仅支持公开视频，并依赖人工或自动字幕。NotebookLM 导入的是字幕转录文本，而不是视频画面；无语音、无字幕或过新的视频可能无法导入。
- Google Drive：导入的 Drive 文件需要持续可查看。来源可以自动同步，但这不会赋予 NotebookLM 编辑原文件的权限；如果原文件被删除或你失去访问权限，该来源可能无法使用。
- 文件与版权：格式和大小限制应以当前导入帮助页面为准。不要上传自己无权使用的文件；分享来源或生成材料前，也要确认你有相应权利。
如何让 Chat 的回答更有用？
- 限定任务和范围：说明要总结、比较、提取日期还是解释概念，并明确需要的数量或格式。
- 指出来源：多份材料容易混淆时，在问题里点选来源子集或提及来源名称。
- 要求可核查的依据：请它为每项结论附上来源引用；随后打开引用核实上下文，不能只看摘录是否与结论相似。
- 区分材料事实与推断：对于材料没有直接回答的问题，要求标出缺失信息，而不是把推断写成原文结论。
Audio Overview 和其他 Studio 输出可靠吗？
Studio 可以把来源转换成学习材料、简报、思维导图或音频概览。Audio Overview 帮助页面列出 Deep Dive、Brief、Critique 和 Debate 等形式，并提供语言、长度和自定义提示等控制；具体选项可能随产品变化。Google 帮助：创建 Audio Overview
这些输出由 AI 生成，可能包含不准确内容，也可能出现音频故障。把它们当作阅读或复习的辅助材料，而非来源本身；引用重要信息时回到原文核对。分享音频还要考虑 notebook 的访问权限和来源版权；下载或分享链接等选项不一定适用于每种账户或来源。

免费额度、计划与隐私如何判断？
Google 的计划说明列出 Standard、Plus、Pro、Ultra 等访问等级，也说明额度可能变化。可用额度与功能会受计划、账户类型、地区及组织设置影响；工作或学校账户还可能需要符合条件的 Workspace 许可或管理员启用。不要把某一额度当作所有用户都适用的固定上限，使用前请核对Google 当前计划与额度说明。
隐私条款也因账户类型而异。Google 的个人账户说明称，资料不会用于训练 Gemini Notebook，除非用户提交反馈；提交反馈时，Google 可能审阅该次交互的完整上下文，包括查询、上传内容和模型回答。Workspace 或 Workspace for Education 的相关说明则称上传内容、查询和回答不会由人工审阅，也不会用于训练 AI 模型。组织账户还可能受 Workspace 或 Google Cloud 的其他条款与设置约束。上传机密资料前，先确认适用于你的账户和组织的计划说明及隐私说明。
