Samsung Put Google’s Research Brain on Your New Foldable. Does It Belong There?

NotebookLM has quietly become the app that power users swear by, the thing you open on a laptop that already has thirty tabs fighting for space. It reads your sources, connects the dots, and answers questions about them. So here is the odd part of Samsung's latest Galaxy Unpacked pitch: that tool, now rebranded Gemini Notebook, comes preloaded on phones you fold in half.

The Galaxy Z Fold 8 Ultra, Z Fold 8, and Z Flip 8 all ship with it built in. On paper that sounds like a real upgrade over yet another chatbot shortcut. In practice, it raises a simple question worth asking before you get excited: is a deep-research desk tool something you actually want to reach for on a phone?

What Gemini Notebook actually does

Strip away the branding and Notebook is a place to dump sources and make sense of them. You feed it links, YouTube videos, chats, and plain written text, and it pulls everything into one spot. From there you can ask questions across all of it at once, and the answers are grounded in the material you gave it rather than the open web. That grounding is the whole point: it is trying to be a researcher that only reads your stack, not the entire internet.

It also turns those sources into other formats. Notebook can spin your pile of research into a slide deck, a set of flashcards, a short video, or an audio rundown that sounds like a podcast about your own notes. Google's own example is planning a European trip: drop in a few travel videos, a couple of blog posts, and some saved links, and let Notebook assemble the plan. Swap in lecture notes, or a stack of PDFs for work, and the pitch stays the same.

The catch: it is not exactly free

Preinstalled does not mean fully unlocked. Some of the more useful Notebook features sit behind Google AI Pro, which normally runs $20 a month. Samsung softens that by bundling six months of AI Pro with each of the new foldables, so you get the full version for a while without paying extra. After that, the bill is yours, and the most interesting parts of the app are the ones most likely to live on the paid side of the line.

Does it belong on a phone?

Here is where the skepticism earns its keep. Notebook is a tool built for focus, for the moment you sit down and actually work through a subject. A foldable is arguably the best phone for that kind of task, because the big inner screen gives you room to read a source and query it side by side. If any phone can make a research tool feel at home, it is this one.

But preinstalling an app is not the same as making people use it. Most of us do our thinking-through-a-topic work at a desk, and the honest question is how often you will open a research notebook while standing in line for coffee. The feature is real, and for students, travelers, and anyone who lives in their notes it could be genuinely handy. Whether it becomes a habit or just another icon you swipe past is the one thing Samsung cannot preinstall.
