Google released NotebookLM for phones and tablets on May 19, 2025. The app turns written documents into audio summaries and helps users understand complex information. It works on iPhones with iOS 17 or newer and Android phones running version 10 or later.
The app arrives after many users asked to have NotebookLM on their phones. “We made this app to help people understand information anywhere,” said Biao Wang, who manages products at Google Labs.
NotebookLM turns documents into audio, much like a podcast. Users can listen while commuting or during daily activities, even without internet. They can pause and ask questions about what they’re hearing, just like talking to someone who knows the material well. Students use it to understand research papers, while professionals review documents during their busy schedules.

The app works with websites, PDFs, and YouTube videos. Users tap the share button on their phone to save content to NotebookLM. The app then breaks down the information and answers questions about it. When answering, it shows exactly where in the original document the information came from.
In March 2025, NotebookLM added support for 50 languages and a new map tool that shows how different topics connect. Personal users gained access in February 2025 through Google’s subscription plans, joining business customers who got it earlier.
Researchers can quickly turn raw data into useful insights. Students use it to understand research papers, office workers review long reports, and writers organize their research materials more easily.
Google promises to protect user privacy. The company doesn’t use uploaded documents or questions to improve its AI. It keeps all materials private in each user’s Google Cloud storage and won’t let anyone read them without permission.
The app is now in both the iPhone App Store and Android’s PlayStore. It helps students, journalists, academics, and professionals better understand their documents, whether they’re in the subway, going through service deadspots, or just looking to use less cellular data.
