Cram vs NotebookLM
Google's NotebookLM is a genuinely impressive free tool: upload your documents and it grounds everything in your sources — chat with them, get audio overviews, and now generate flashcards, quizzes, and a step-by-step 'Learning Guide.' It's a research and study assistant in one. Cram is narrower and more purpose-built: turn your material into a flashcard deck and actually memorize it with spaced repetition, on your iPhone, offline.
Both use AI on your own documents. The difference is what each is for: NotebookLM is a sources-grounded research assistant that can produce study aids; Cram is a dedicated flashcard app built around the spaced-repetition review that makes things stick.

What is NotebookLM?
NotebookLM is a free, sources-grounded AI tool from Google. You upload documents and it answers questions grounded in them, generates audio overviews, and now creates flashcards, quizzes, reports, and a guided 'Learning Guide' tutor. It runs on the web and as a mobile app on iOS and Android, syncs your progress across devices, is powered by Gemini, and is free with a Google account.
Where Cram stands out
Built around spaced-repetition review
NotebookLM generates flashcards and tracks what you've reviewed, but it isn't a spaced-repetition scheduler. Cram brings each card back right before you'd forget it and adds an exam-date countdown — the mechanism that turns studying into lasting memory.
Offline, on your device
NotebookLM is a cloud AI tool that needs a connection. Cram's decks live on your device, so review works on a plane or before an exam with no signal.
A focused study app, not a research suite
NotebookLM does research, chat, audio overviews, and study aids. Cram does one thing cleanly — material in, deck out, spaced-repetition review — with nothing to navigate.
More kinds of input on the phone
Beyond documents, Cram turns your typed notes, pasted text, web links, photos or scans of notes, and any topic into a deck — the sources you actually have on your phone.
Where NotebookLM stands out
Free and sources-grounded
NotebookLM is free and grounds every answer in your uploaded documents, with citations back to the source — excellent for researching and understanding material, not just memorizing it.
Audio overviews and a guided tutor
Its audio overviews and the 'Learning Guide' are standout features for understanding a topic deeply, which a flashcard app doesn't try to do.
Backed by Google and Gemini
NotebookLM runs on the latest Gemini models with a large context window, across web, iOS, and Android. Cram launches on iPhone first.
