Frequently Asked Questions
What is the best AI for exam preparation?
For most students it is StudyGlen, because it covers the two things that move an exam score: answering practice questions from your own material, and reviewing on a schedule until the exam. Add a PDF, photos of your notes or pasted text and your exam date, and it builds a study plan by topic, with practice questions that explain every answer and weak topics brought back, plus a flashcard deck scheduled with FSRS-6 and paced to that date. ChatGPT's study mode is the best tutor when you are stuck on a concept, and Gemini Notebook (formerly NotebookLM) is best for summarizing a stack of readings.
Which AI is best for studying for exams for free?
ChatGPT's study mode is free on every plan, with limited uploads. Gemini Notebook is free for up to 50 sources per notebook, and Anki is free on desktop, Android and the web. StudyGlen's free account gives one AI practice round, quiz or flashcard deck a day, with unlimited review, and making the study plan costs nothing; a practice test in the plan needs credits. Knowt's Learn mode is free and unlimited, with ads, and RemNote's free plan schedules one exam.
What is the best AI for exam answers?
If you mean answers during the exam: none. Using AI in an exam counts as misconduct at most schools, and no tool on this list is built for it. If you mean answers to practice questions, that is the best way to prepare: generate questions from your course material, answer them before you look, then read why each answer is right. StudyGlen writes an explanation on every answer, and ChatGPT's study mode gives hints and feedback instead of handing over the answer.
Is ChatGPT good for exam preparation?
Yes, for understanding. Study mode, available on every ChatGPT plan, asks guiding questions, gives hints and can quiz you one question at a time from notes or PDFs you upload. What it does not do is bring material back on a schedule: there is no spaced-repetition calendar and no deck paced to your exam date. Many students pair it with a flashcard app — StudyGlen, Anki or RemNote — for the weeks before the exam.
How do I use AI to study for an exam?
Start early and work from your own material. Add your notes or a PDF and your exam date, and StudyGlen finds the topics and plans short practice rounds for each day. Answer every question before you look, then read the explanation for each one you missed; weak topics come back. Take a full practice test when you have covered the topics, and review the flashcards that are due each day — a deck with a date keeps the last three days for review only. On exam day, do a short Last look on what you need most. When a topic still does not make sense, ask a tutor such as ChatGPT or Gemini.
Can AI make a study plan for my exam?
Yes. In StudyGlen you add your PDFs, photos or pasted notes and pick your exam date, and it finds the topics and plans short practice rounds for each day until then. Making the plan is free, and one round a day uses your free credit. Weak topics come back, you can add a full practice test on any day for 2 credits, and exam day has a short Last look quiz. The plan is on the web, not in the mobile apps yet. RemNote's Exam Scheduler and Knowt's study plans also work to an exam date, and ChatGPT can draft a plan in the chat.
What is the best spaced repetition app for an exam date?
StudyGlen and RemNote both plan to a date. In StudyGlen you pick this week, this month or a date of your own when you make a deck; it spreads the new cards over the days left, keeps the last three days for review, schedules every review with FSRS-6 and shows whether you're on track or behind. RemNote's Exam Scheduler gives you a daily practice plan for your exam date, with one exam on the free plan. Anki has FSRS too, but no exam-date setting built in.
Is NotebookLM good for studying for exams?
Yes, for understanding your readings. NotebookLM, now called Gemini Notebook, turns up to 50 sources per notebook into study guides, briefings, mind maps and audio overviews, and makes flashcards and quizzes with an Explain button — free. It does not schedule reviews: you retake the cards you missed, and nothing is paced to your exam date. Use it to summarize, and a spaced-repetition app to remember.
