- NotebookLM now supports AI video overviews in more than 80 languages
- Both video and audio summaries are created from user-uploaded documents
- Video overviews resemble clean, slide-based presentations for clarity
- Expansion makes NotebookLM a global tool for students and professionals
Google has rolled out a major update to its AI research assistant NotebookLM, giving it the ability to create video summaries in more than 80 languages. Until now, the platform’s video overview feature was restricted to English, but the global expansion marks a significant shift toward accessibility and inclusivity.
The service, which first introduced audio summaries in the form of AI-generated podcasts, quickly caught attention for its ability to transform notes and uploaded documents into digestible explanations.
With this upgrade, Google is positioning NotebookLM not just as a research companion for English speakers, but as a worldwide study and work tool that caters to students, academics, and professionals across diverse regions.
From Podcasts to Slides
NotebookLM originally debuted with Audio Overviews, turning written materials into podcast-like explanations delivered by digital hosts. Soon after, Google extended the feature into Video Overviews, adding simple slides with text and illustrations that match the narration.
While effective, the videos had a limitation, they only worked in English. That created a gap for international users who wanted the same accessible format in their own language. Today’s update closes that gap. Users can now upload research papers, reports, or even meeting transcripts, and generate narrated video summaries in languages ranging from Tamil to Polish.
These videos are not designed to dazzle with cinematic flair. They aren’t animated explainers or flashy social media reels.
Instead, the format resembles a minimalist slide presentation: clear, structured, and easy to follow. Google’s goal here is clarity, not spectacle, making the tool more useful for people who need information explained quickly and directly.
Grounded in Real Documents, Not Guesswork
One of the standout aspects of NotebookLM is its grounding in user-provided materials. Unlike some AI tools that generate content based on broad training data or web scraping, NotebookLM focuses exclusively on the documents users upload.
That means the summaries, whether audio or video, aren’t fabricated or based on vague prompts. Instead, they’re synthesized from the actual text and references you provide.
For researchers, professionals, or students, that level of reliability can be a game-changer. It ensures that the AI sticks to the facts of your work rather than wandering into hallucinations.
This foundation also allows NotebookLM to be a versatile tool. It can condense textbooks into digestible lectures, turn weekly meeting notes into shareable recaps, or help explain dense policy documents in a simple narrated slideshow.
Practical Benefits for Everyday Use
The real impact of NotebookLM’s multilingual upgrade is in its everyday usefulness. Imagine a researcher uploading dozens of academic papers in English but wanting to share the findings with colleagues in Catalan or Portuguese. Or a student in Poland using the tool to break down complex English-language study material into their native tongue.
With audio overviews, users can now listen to extended recaps while commuting, cooking, or multitasking, no need to sit in front of a screen. For many, this will feel like having an on-demand lecturer who speaks their preferred language.
Meanwhile, the video option creates structured, seven-minute presentations complete with narration and slides. Users can share these directly with peers or download them for offline use. It’s a modern alternative to the time-consuming process of creating a PowerPoint or lecture deck from scratch.
Professionals who deal with international teams stand to gain the most. Instead of relying on everyone’s English comprehension, companies can use NotebookLM to generate summaries in multiple languages, making communication smoother across global offices.
Accessibility Meets Global Scale
Google’s decision to expand NotebookLM into more than 80 languages speaks to a larger vision: making AI tools accessible beyond the English-speaking world. While many AI platforms have focused on English as a default, Google is leveraging its expertise in multilingual systems to broaden the reach of its tools.
This aligns with the company’s broader efforts to integrate AI into education, productivity, and research workflows. By removing language barriers, Google is positioning NotebookLM as a resource not just for individuals but for institutions, classrooms, and businesses operating across borders.
The update also reflects the growing demand for tools that can translate not just words, but entire learning experiences. By combining narration, slides, and summaries in native languages, NotebookLM becomes more than a research tool, it becomes a teaching companion.
Still Some Challenges Ahead
Despite the exciting expansion, NotebookLM is not without limitations. AI-generated summaries can sometimes flatten nuanced arguments or overlook subtle context in complex materials. While the tool is grounded in uploaded documents, the way it condenses and presents information may occasionally miss the finer points of an argument or analysis.
For now, Google seems focused on clarity and accessibility over depth. That trade-off may frustrate some advanced users who need every detail captured. But for the majority, especially students and busy professionals, the balance of simplicity and accuracy is likely to be a welcome improvement.
How to Try It Out
Getting started with the new features is straightforward. Users upload their sources—whether notes, PDFs, or links, then click the Video Overview button. Within minutes, NotebookLM generates a narrated video of around seven minutes, complete with slides. The result can be shared online, downloaded, or saved for future use.
Audio overviews function similarly, providing a comprehensive recap in a podcast-like format. Together, these two features give users flexibility: video for visual learners, audio for those on the go.
For anyone juggling research, studies, or cross-border collaboration, the expansion into dozens of languages makes NotebookLM a much more powerful and inclusive tool.
Looking Ahead
NotebookLM’s multilingual upgrade highlights how quickly AI tools are moving from niche experiments to everyday utilities. What started as an English-only assistant is now evolving into a global platform capable of breaking down information barriers.
Whether it’s students preparing for exams, professionals coordinating across continents, or researchers trying to share findings worldwide, the ability to generate accessible summaries in local languages could reshape how people digest and share knowledge.
The technology may not yet be perfect, but its practical value is undeniable. With today’s expansion, Google has made NotebookLM less of an English-first experiment and more of a global learning companion.
