NotebookLM: Focus on new features for 2025

NotebookLM, the powerful AI tool initially launched as Project Tailwind at Google I/O 2023, then officially rebranded in December of the same year, marks a decisive turning point in its evolution in the spring of 2025.

An anticipated mobile app: AI in your pocket

The wait is finally over!As of May 20, 2025, NotebookLM takes a major step forward by becoming accessible directly from your mobile devices.

The native app, available on Android and iOS, is much more than a simple adaptation of the web version.

This mobile version retains all the flagship features that users value so highly:

– Intuitive import from a variety of sources (PDFs, websites, YouTube videos, plain text)
– Context-sensitive querying on your documents
– Instant generation of personalized study guides
– Creation of Audio Overviews to take anywhere

The interface has been specially optimized to ensure a smooth experience even on the move, enabling users to remain productive wherever they are.

Transparent synchronization between web and mobile versions ensures that your notebooks and research remain accessible and up-to-date on all your devices.

The mobile version represents a significant step forward for researchers, students and professionals who can now harness the power of NotebookLM at any time, transforming waiting or commuting times into productive learning and analysis sessions.

Audio Overviews: A multilingual and interactive revolution

The Audio Overviews feature, which transforms your sources into veritable AI-generated podcasts, undergoes a spectacular evolution with:

– Support for over 50 languages thanks to Gemini integration, making this technology accessible to a global audience
– Deeper customization of narrative style, pace and length for NotebookLM Plus users
– Real-time interaction while listening – a major innovation enabling questions to be asked, points to be explored in greater depth or clarifications to be sought without interrupting the listening session

For hearing learners or mobile professionals, this feature radically transforms the assimilation of complex information.

Now it takes just a few clicks to convert a dense scientific article or technical report into clear, digestible audio content, tailored to your comprehension level and specific needs.

If you’re looking to deepen your understanding of the core capabilities of NotebookLM as an information management tool, this feature perfectly represents the tool’s philosophy: turning the complex into the accessible.

NotebookLM Plus: A premium offer for demanding users

Google rolls out NotebookLM Plus, an advanced version aimed at professionals, teams and companies with intensive document research and analysis needs. This premium package introduces:

– Fivefold usage quotas for Audio Overviews, sources and notebooks
– Advanced customization options to fine-tune the tone, complexity and structure of generated responses
– Collaborative notebooks with real-time sharing and detailed usage statistics
– An enhanced level of security and confidentiality, meeting the standards of the most demanding companies

NotebookLM Plus integrates seamlessly with the Google Workspace and Google One AI Premium ecosystems, making it easy to adopt in professional and educational environments already oriented towards the Google ecosystem.

A completely redesigned Interface for maximum productivity

NotebookLM’s user interface gets a makeover with a strategically designed three-pronged approach:

1. Sources panel on the left: intuitive management and direct selection of reference documents
2. Center chat window: fluid interaction with AI
3. Studio area on the right: creation, organization and formatting of generated content

This visual overhaul is accompanied by significant technical improvements:

– Source limit per notebook increased from 50 to 300, or around 150 million words per project
– Simplified navigation with extended keyboard shortcuts
– More detailed and accessible interaction history

The new design makes frequent actions more accessible while facilitating the management of complex projects requiring the analysis of many sources simultaneously.

Extended analysis and import capabilities

NotebookLM takes a decisive step forward in the understanding of mixed content with:

– Intelligent analysis of images embedded in PDFs, enabling AI to understand and interpret graphs, diagrams and other visual elements present in your documents
– The “Discover Sources” function which automatically suggests relevant web resources based on your current research, considerably enriching your document base without leaving the interface

These enhancements make the tool particularly powerful for analyzing academic documents, technical reports or educational content, which often rely on complex visual representations.

Mind map interactive : The visual dimension of your research

The introduction of an interactive Mind Map represents a major advance in the way we explore and organize information. This feature enables:

– Instantly visualize connections between concepts and sources
– Intuitively navigate through the structure of your research
– Discover unexpected relationships between different parts of your documentation
– Visually reorganize concepts to bring out new ideas

For researchers working on complex or interdisciplinary topics, this mind-mapping tool offers a new and stimulating perspective on their data, sometimes bringing out novel angles of analysis.

Why NotebookLM distances its competitors

What fundamentally sets NotebookLM apart in the AI assistant ecosystem is its rigorously source-rooted approach.

The AI bases its responses exclusively on documents explicitly selected by the user, drastically reducing the risk of factual errors or “hallucinations” often encountered with other tools.

This reliability-focused methodology is coupled with complete traceability – every piece of information provided can be instantly verified in the original sources, accessible at the click of a button.

For academics, journalists, researchers or professionals working with sensitive data, this transparency represents a decisive advantage.

NotebookLM’s contextual and factual approach sets a new standard for reliability in the AI assistant ecosystem, meeting the growing expectations of professional users.
