Google has officially launched the NotebookLM app for Android and iOS users, expanding its AI-powered research and note-taking assistant beyond desktop platforms. The release, which arrived a day earlier than expected, comes just ahead of the company’s annual developer event, Google I/O 2025.

Initially introduced in 2023, NotebookLM was previously only accessible via web browsers. The standalone mobile apps mark a significant evolution, offering enhanced mobility, accessibility, and user convenience for students, researchers, and knowledge workers.

A Powerful AI Assistant, Now in Your Pocket

NotebookLM is designed to simplify the process of digesting complex information. Leveraging generative AI, the app can analyze large volumes of data, summarize content, and respond to user queries about uploaded documents, websites, PDFs, and more. The tool is ideal for breaking down research papers, academic journals, business reports, and other dense source materials.

Now that the app is available on Android and iOS, users can benefit from this AI assistant wherever they go — whether in a classroom, on a commute, or while multitasking at work.

Smart Summaries and AI-Generated Podcasts

One of the key features making its way to mobile is Audio Overviews — AI-generated podcast summaries based on the source material you upload. NotebookLM can convert documents into concise spoken content, giving users a more immersive and flexible way to absorb information.

The app supports offline playback and background audio, ensuring users can continue listening while switching apps or when disconnected from the internet. Whether you’re reviewing lecture notes or catching up on industry research, these AI-generated summaries are built to save time and enhance comprehension.

Seamless Note Management and Source Integration

The mobile version of NotebookLM offers full access to all notebooks created on desktop. Users can also start new notebooks directly from their smartphones. The interface allows smooth navigation between different topics and documents, making the organization of large research projects effortless.

An additional convenience is the ability to add sources directly from mobile browsers or apps. When viewing a website, PDF, or YouTube video, users can simply tap the Share icon and select NotebookLM as a destination. This functionality allows for real-time content capture and annotation, a valuable tool for researchers, journalists, and students.

Designed for Accessibility and Usability

NotebookLM on Android and iOS is built with a modern, clean interface and features support for both light mode and dark mode, which automatically align with the system preferences of the user’s device. The design mirrors Google’s Material You aesthetics and offers fluid transitions between sections.

Whether reviewing documents in a dimly lit room or under bright sunlight, the app dynamically adapts to maintain visual comfort and readability.

An Early Launch Before Google I/O 2025

The early release of the NotebookLM app just one day before Google I/O 2025 suggests that Google might have further enhancements or integrations to unveil during the keynote. Given the company’s ongoing investment in AI, NotebookLM may soon support additional functionalities, deeper integration with other Google Workspace tools, or expanded language and voice support.

With education and enterprise users increasingly reliant on mobile solutions, Google appears poised to make NotebookLM a cornerstone of its AI-first productivity ecosystem.

A Major Step Forward for Mobile AI Tools

Since its inception, NotebookLM has stood out for its ability to blend note-taking with deep document understanding, offering a unique advantage over conventional tools. By bringing this powerful functionality to Android and iOS, Google is democratizing access to smart productivity tools and reinforcing its position as a leader in mobile AI innovation.

As more users embrace hybrid work and study environments, tools like NotebookLM are becoming essential. The app’s intelligent summarization, question-answering capability, and integration with daily workflows place it well ahead of traditional note-taking apps.
