Google just launched a standalone NotebookLM app for Android and iOS, officially bringing its AI-powered research assistant to your phone.

This isn’t just another AI notepad—NotebookLM turns your documents into a living, searchable knowledge base that actually understands what you’ve uploaded.

Originally unveiled as Project Tailwind at Google I/O 2023, NotebookLM was designed to be a “source-grounded AI”—meaning it reads your uploaded files (think PDFs, Google Docs, text files) and gives answers based only on what’s inside them.

No internet scraping, no hallucinations—just facts you fed it. Now with the mobile app, that experience is no longer locked to your laptop.

The mobile version feels less like a productivity tool and more like a personal research companion.

You can highlight chunks of text, ask follow-up questions, and even summarize long docs—all from your phone.

Students, journalists, and researchers will probably eat this up, but honestly, it’s also a solid win for anyone juggling multiple projects or reading-heavy work.

The UI is clean and minimal. The app keeps your sources organized and lets you chat with them individually or in groups.

You can still upload and sync content through Google Drive, and Google says the mobile app supports “persistent memory”—meaning it remembers your previous conversations and what it learned from your docs.

Think of it like an AI that actually knows your files better than you do.

This launch is part of Google’s bigger play to bring AI utility into everyday workflows without feeling like a science project.

And compared to general-purpose chatbots, NotebookLM feels refreshingly specific. It's designed not to replace your brain, but to help you use it better.

The mobile app is now available on the Play Store for Android and will be rolling out on iOS soon.

If you’ve been waiting for an AI that actually understands your context—this might be the one to download.
