Comparison
SparkMentor vs NotebookLM: study your sources or learn the subject?
NotebookLM summarises what you give it. SparkMentor teaches: it explains a subject step by step, practises with you, and plans your exam, and it reads your notes too.
Why SparkMentor wins
- You need to learn to solve problems, not just understand readings
- You want a tutor that asks you questions and tracks your slips
- You're working toward an exam with a fixed syllabus
Same question, two approaches
The difference is easiest to see on one problem.
Same question: Explain my lecture notes on entropy.

In more detail
01
Summaries don't get you through exams
Grades come from skills: solving problems, writing essays, answering under time pressure. NotebookLM summarises material; SparkMentor builds the skill.
02
SparkMentor reads your notes too
You can upload notes and documents to SparkMentor and ask for explanations and summaries. The difference is what happens next: it tutors you on them, quizzes you and logs what you got wrong.
03
Price
NotebookLM is free, with higher limits bundled into Google's AI plans. SparkMentor starts free with 1,000 credits.
