Google的NotebookLM AI研究工具在去年推出后，一直致力于通过AI“播客主持人”以对话方式解释用户上传的资料，并能生成思维导图和研究报告。近日，Google宣布为其新增“视频概览”功能，作为对播客式音频格式的补充。用户现在可以将上传的文档（包括音频、PDF、文档、图片和网站）转化为视觉演示，即“叙事幻灯片”。AI主持人会根据文档内容创建新的视觉元素，并引用其中的图片、图表、引语和数据，如同一个AI生成的PowerPoint演示文稿。此功能允许用户根据学习目标和目标受众自定义演示文稿。视频概览目前首先支持英语，未来将扩展到更多语言。此更新旨在为学生等用户提供更具吸引力的学习方式，是Google近期推出的一系列教育AI工具和功能之一，与OpenAI的Study Mode等竞品共同发力教育领域。

📊 **NotebookLM新增视频概览功能**：Google的NotebookLM AI研究工具现已支持将用户上传的各类文档（如PDF、音频、图片等）转化为“叙事幻灯片”形式的视频概览，作为其原有的音频讲解和图表生成功能的补充，为学习者提供更丰富的视觉化学习体验。

🎥 **AI驱动的视觉化内容生成**：该视频概览功能由AI驱动，能够智能提取文档中的关键信息，如图片、图表、引语和数据，并结合AI生成的新视觉元素，以更直观的方式呈现学习内容，极大地增强了信息的传达效率和趣味性。

🎨 **高度可定制的学习体验**：用户可以根据自己的学习目标和目标受众，对生成的视频概览进行个性化定制，确保内容呈现方式与学习需求高度契合，从而实现更高效、更有针对性的学习。

📚 **教育领域的AI应用深化**：此功能的推出进一步凸显了Google在教育领域对AI技术的投入。结合其在AI Mode in Search中的更新（如创建学习指南、PDF问答等），Google正积极构建一个全面的AI教育生态系统，以支持学生的学习和研究需求。

For the visual learners, Google's NotebookLM AI research tool can now make videos. On Tuesday, Google announced the addition of Video Overviews as an alternative to its podcast-style audio format.

NotebookLM launched last year as an AI-powered teaching tool that employs one or two AI "podcast hosts" to explain topics in a conversational way, based on sources you upload to the platform. You can also generate mind map diagrams and research reports. 

Now when you use NotebookLM, you can choose to turn your sources into a visual presentation, or what Google calls "narrative slides." Users can upload various types of documents like audio files, PDFs, documents, images, and websites to the Notebook and the "AI host creates new visuals to help illustrate points while also pulling in images, diagrams, quotes and numbers from your documents," as Google described in the announcement. It's effectively an AI-generated PowerPoint presentation on the documents you upload.

Google also said you can customize the presentation based on criteria like learning goals and target audience. Video Overviews is rolling out in English today, with support for more languages coming soon.

NotebookLM is for anyone and everyone, but an obvious use case is students looking to learn about a new topic in a more engaging way. With kids going back to school soon, this is one of many education-focused AI tools and features Google has recently introduced. Also on Tuesday, Google shared several new updates to AI Mode in Search, including a new Canvas workspace for creating study guides, the ability to upload and ask questions about PDFs, and screensharing in Chrome for chatting with AI Mode about a certain webpage. 

Not to be outdone, OpenAI is also ramping up its focus on education tools, with Study Mode that turns ChatGPT into a teacher using the Socratic method. With the end of summer in sight, the message is clear: think of Google and OpenAI for homework help and more.
