Why You Should Only Use Google’s NotebookLM in a Browser

I am the biggest booster of Google's NotebookLM, an AI tool that functions like a personal ChatGPT. I have recommended it for studying, used it for my own work loads of times, and generally found it to be one of the best bits of software available right now. But recently, I tried using it on my phone, not just on my computer browser—and it fell surprisingly flat. Here's how I've been managing to use it via mobile, anyway, and why you should stick to the computer version for now.

What is NotebookLM?

NotebookLM is a language model that only uses resources you provide. Like ChatGPT, it can offer summaries, outlines, and studying or organizational help, but unlike ChatGPT, it's not pulling from the World Wide Web to do that. Instead, you upload PDFs, links, plain text, and documents and, when you ask it a question, it relies only on those to give you an answer.

Here's a practical example.: I use it a lot when I'm writing an article that features a load of interviews. I copy and paste my interview transcripts into NotebookLM, then prompt it, to, say, "Find me three quotes about the value of good sleep." If three of my sources mentioned how important it is to get a good night's rest, I'll get three quotes right away, plus a hyperlink to where they each appear in their respective interview, so I can go back and read the context around them. It makes being organized so much easier and I don't waste time searching, word by word, through every transcript for what I need.

For studying, it's even better. You can upload all the slide decks, e-texts, and notes you have from a class, then ask it to generate practice quizzes, flashcards, summaries, or essay outlines. One of its coolest features is that it will even create a fake podcast, complete with two hosts who have vocal ticks and even vocal fry. The two AI hosts discuss the material from your sources in an informational, conversational way, like a real podcaster might, and you can listen to it and learn wherever you are.

It's been incredibly helpful for me, and it doesn't feel unethical to use, like other AI chatbots, because it's synthesizing information I already found, compiled, and put the work in on. It doesn't feel like I'm cheating when I use it; instead, it feels like I'm getting a little boost in my organization, but still doing most of the work. Plus, there's never a risk that it will make up a fake fact or pull in information that is irrelevant or faulty, like there is with ChatGPT. It relies only on what you give it.

The mobile app problem

All of that said, I became and stayed obsessed with this after only using it on my desktop browser for the last six months or so. Last weekend, though, I was studying for an upcoming certification exam and was, as usual, using NotebookLM to generate flashcards, quizzes, and fake podcasts. But I was also cleaning my apartment and doing the laundry, which involved a lot of running to and from the laundromat. I decided to use the NotebookLM iPhone app so I could study on the go; I assumed that since the product is so stellar on the computer, it would be great on the app, too. It was not.

On the app, all you can do is review your sources, talk to the chatbot, and listen to your generated podcasts. Here's what you can't do:

• Generate flashcards

• Review existing flashcards

• Generate a quiz

• Take existing quizzes

• Select the sources from which you make a podcast, quiz, flashcards, or chat topic

One of the best things about the browser version is you can toggle sources on and off. So, if you upload a separate PDF for five different book chapters, you can select only Chapter 1 and Chapter 2 before generating a quiz or flashcards, for instance. If you keep them all selected, your quizzes, flashcards, podcasts, or chats will pull from all of them. By narrowing the scope, you can study more specifically.

You can't do that on the app, but it doesn't actually matter because you can't generate (or use) anything on the app, anyway. You can generate a podcast, but only one that pulls from all your sources. The other features—quizzes and flashcards—aren't available at all.

Workarounds for NotebookLM

The first workaround I found was a little annoying: I generated a podcast for every chapter using my computer, then listened to them through the mobile app on my phone while I ran my errands. I had to stay on top of my schedule, bouncing from cleaning to laundromat to computer and back again, so I wouldn't find myself without a study podcast to review, but all in all, I got the hang of it. You can't do this for flashcards, quizzes, or mind maps, but if you're after the podcasts, this works with some pre-planning.

The second workaround is not to use the app at all. Most websites and companies want to push you toward app use, presumably for data-collection purposes, but never forget there is a browser on your phone, too. I navigated to the NotebookLM website on my mobile browser and, though it's smaller and harder to navigate than the computer, have been able to use it to generate flashcards, quizzes, mind maps, and more. You can check and uncheck sources on the mobile browser version, which is ideal.

I'm hopeful the app will improve. NotebookLM is such a great resource that has helped me a ton, but it would be much better if it were more usable in its app format. I can't always be attached to my laptop; the real value of studying with flashcards, especially, is that they should be accessible and reviewable anywhere via my phone.
