iTutor vs NotebookLM
NotebookLM answers questions about your sources; iTutor turns them into a complete study system.
At a glance
Google's NotebookLM is excellent at answering questions strictly from your uploaded sources and generating audio overviews. iTutor (itutor.study) is also fully grounded in your materials, but goes further: it auto-generates flashcards with spaced repetition, auto-graded quizzes, exam simulations, mind maps, study plans, and an explorable 3D study world — with a voice tutor in 12 languages and LMS export.
When to pick what. Pick NotebookLM if you only want grounded Q&A and an audio overview of your documents. Pick iTutor if you want that grounding plus the full study toolkit — flashcards, quizzes, exams, planning, progress tracking, and voice — to actually prepare for an exam.
Pricing
NotebookLM is free with a Google account, with higher limits on paid Google plans. iTutor's core features are free forever, no credit card; Pro is $4.99/month.

Frequently asked questions
Is iTutor like NotebookLM?
Both are grounded in your uploaded materials, so neither invents facts from the open web. The difference is scope: NotebookLM focuses on Q&A and audio overviews, while iTutor adds flashcards, auto-graded quizzes, an exam simulator, mind maps, study plans, and a voice tutor in 12 languages.
Does iTutor avoid hallucination like NotebookLM?
Yes. Every iTutor generator is grounded in the specific materials you upload, using retrieval over your documents, so questions and answers trace back to your sources rather than general knowledge.
Can NotebookLM make flashcards and quizzes?
Not the way a dedicated study tool does. iTutor auto-generates flashcards with spaced repetition and auto-graded quizzes from the same documents, plus exam simulations and study plans.
