NotebookLM, the acceptable face of Google AI, is getting an app in May

NotebookLM, the Google research tool that gained notoriety for its uncanny AI-generated podcasts, is getting an official app on May 20, 2025. You can pre-register for the Android or iOS version of the app right now and have it automatically downloaded to your device on May 20, the first day of Google I/O 2025.

Based on the listings in the Play Store and App Store, Google seems intent on keeping all of the core functionality of the web version of NotebookLM intact for its mobile debut. You can upload a variety of different sources (PDFs, website URLs, YouTube videos and copied text) and have NotebookLM, powered by Gemini, do stuff with them. That could be answering specific questions, generating study guides or creating an Audio Overview, the previously-mentioned "podcasts."

NotebookLM started life as Project Tailwind back at I/O 2023 and has gradually transitioned from research project to real product over time. The service officially launched as NotebookLM in December 2023 and gained Audio Overviews in September 2024. As of April 2025, NotebookLM is now offered in more than 50 languages. Getting an actual app release is the best sign yet the service is here to stay.

Critical to its sucess, NotebookLM makes more sense as a tool you can trust than basically any other Gemini product. The service's output is grounded in documents and sources you choose. That means Google's AI is less likely to hallucinate because it's quoting a research study directly, and it's easier to double check its answers because you can view the source directly in NotebookLM.

Google has already signaled that I/O 2025 will be Gemini-focused by breaking out Android announcements into their own stream, so there's a good chance NotebookLM won't be the only AI product getting some love on May 20. It remains to be seen whether Google has any ideas as cogent as "an AI that helps you digest long PDFs," though.
