The most useful AI tool right now

In addition to summarizing and creating podcasts, NotebookLM now supports converting document content into visual videos with voiceovers.

Feature to create videos from original documents on NotebookLM.

Google has just announced a series of new features for NotebookLM, an AI software that supports the synthesis and summary of documents in many different formats. Users can provide original documents and then ask the tool to analyze, summarize, answer questions, come up with ideas or convert content into podcasts.

According to Google statistics, Vietnam is in the top 10 countries/territories using NotebookLM the most globally, alongside India, Japan, the US...

Although it was only launched in June, NotebookLM’s public notebook feature has recorded more than 140,000 shared content. In the Asia- Pacific region, popular public notebooks come from Korea, Vietnam, Taiwan, and Japan, covering a wide range of topics.

Convert documents to video

The first new feature of NotebookLM is called Video Overviews. First announced at the I/O 2025 conference, this mode allows document content to be converted to video, helping to grasp information quickly and more easily.

According to Google, Video Overviews is a “visual alternative” to Audio Overviews, a feature that creates podcasts with AI guests. Instead of reciting the entire content of the original document mechanically, NotebookLM will summarize the main points in the document, presented as an interview between two people to increase interaction.

NotebookLM supports importing text documents, websites or YouTube videos (up to 50 sources). After providing the documents, in the Studio screen on the right, click Video Overview and wait a few minutes, the tool will convert the content into video.

Currently, the content created by Video Overviews takes the form of presentation slides with illustrations, diagrams, quotes, and figures extracted directly from the document. For longer content, the new feature can explain data, summarize processes, and visualize some complex concepts.

NotebookLM videos vary in length depending on the amount of content included, with an average creation time of 5-10 minutes. Videos open with a title, question mark, and key quote, followed by the content in large sections. Important concepts are highlighted, and there is even a timeline for historical content.

In addition to images, the video also has a voiceover. Similar to Audio Overviews, the voiceover in the video has a clear and natural tone, not too stiff or robotic like most other AI tools.

The design, layout, and fonts in the video follow Google's general standards. All videos have the NotebookLM logo to identify AI-generated content.

NotebookLM's presentation layout is based on user-supplied document content.

Video Overviews users can tap the Menu button in the upper right corner to enter additional requests, such as content to focus on, clarify goals, describe the video's audience, video structure, etc.

In addition to converting content to video, users can still ask analytical questions about the original material in the text interaction between the screens.

Video Overviews on NotebookLM are currently only available in English. Google says it will add more languages ​​and video formats in the future. The free version of NotebookLM has a daily usage limit. If you want to create more videos, you'll need to purchase plans like Google AI Pro (starting at $24/month).

Refer to information, in-depth research

The update to NotebookLM also changes the Studio interface, the area on the right side of the screen to choose the summary format. Currently, Studio supports 4 formats including video, audio (podcast), mind map and text document.

In the new version, Studio allows you to create and store multiple versions of a summary format. For example, you can create multiple language versions with Audio Overviews, which is great for sharing your notebook with the community.

If you are creating a notebook for a study group, you can create multiple videos and podcasts related to the content of each specific role. During exam preparation, you can ask NotebookLM to create mind maps and summary videos, each focusing on different lesson content.

The Studio interface is also more intuitive with a content creation button at the top, content will appear in a list below, and multiple items can be created and viewed at the same time. According to Google, the new interface for Studio will be widely released in the coming weeks.

Finally, the NotebookLM homepage adds a Featured Notebooks section , which includes materials from reputable authors, publishers, and nonprofit organizations around the world. Notebook topics are quite diverse, such as in-depth scientific research, travel guides, lifestyle, and expert advice.

Users can interact with the notebook through NotebookLM features such as reading original documents, asking questions, listening to audio/video summaries, reading pre-made text or mind maps (if available).

According to Google, NotebookLM's new features “make it more intuitive and convenient than ever to dig deeper into a wide variety of topics.”
