The best AI study app depends on what you do with your material. Anki is best for free, customisable flashcards, Quizlet for ready-made shared decks, NotebookLM for asking questions across your own sources, ChatGPT for flexible explanations, and Type to Study for turning a topic or a course book into a full course with lessons, typed recall, flashcards and a graded exam. No single app wins at everything, so this guide says what each one does well and where it falls short.
How to judge a study app
Pretty interfaces and AI features matter less than whether the app makes you retrieve information from memory. The research summarised by Dunlosky and colleagues in 2013 rated practice testing and distributed practice as high-utility techniques, and highlighting and rereading as low-utility. So ask four questions of any app:
- Does it make me produce answers, or only show me summaries?
- Does it schedule repeat reviews over days and weeks (spaced repetition)?
- Can it work from my own course material, not only generic content?
- Can I check its claims against a source?
Quick comparison
| App | Best for | Main limit |
|---|---|---|
| Type to Study | Building a whole course from a topic or your files, then typing it, recalling it and sitting a graded exam | Web app only, English interface, no shared deck library; paid after a 7-day trial |
| Quizlet | Finding existing flashcard sets and quick study modes | Set quality varies; many features sit behind a paid plan |
| Anki | Serious long-term memorisation with full control over spaced repetition | Steep learning curve; you make or import your own cards; the iPhone app is paid |
| StudyFetch | Uploading notes or slides and getting AI-generated study material | Subscription tool; check current free limits |
| Mindgrasp | Summarising and questioning documents and lectures quickly | Summary-first, so less built-in recall practice |
| Knowt | Flashcards and notes with a free tier and a social, Quizlet-style feel | Depth of spaced repetition and exams is lighter |
| NotebookLM | Asking questions across your own sources with citations | Not a study scheduler; no typed practice or graded exams |
| ChatGPT | Flexible explanations, example problems, rewriting notes | Can state wrong things confidently; no schedule, no record of progress |
| Brainscape | Confidence-based flashcards with spaced repetition | Mostly flashcards; check what the free plan covers |
| RemNote | Linking notes and flashcards in one place | Takes time to set up; best if you like structured note-taking |
Verdicts, app by app
Type to Study
Type to Study makes a course from a topic or from your own PDF, Word, text or Markdown files, up to 5 files at a time. It researches topics from public sources and lists them. Lessons have a Read mode and a Type mode where you type the lesson on an index card, then a recall pass that hides the key terms. Flashcards, unit quizzes with typed answers, an AI tutor that answers from your lessons, and a freshly generated final exam with a readiness score come with it. It suits people who want the whole loop in one place, and especially anyone studying a long course book. It is not the right pick if you want a huge library of other people's decks, an offline app or a native phone app. It has a 7-day free trial with no card, then $10 a month or $60 a year.
Quizlet
Quizlet's big strength is its library: for many courses someone has already made a set. That is also the weakness, because you cannot always trust a stranger's cards. Several of its study modes and AI features are limited on the free plan, so check the current plan details on its site.
Anki
Anki is the favourite of medical students for good reason. Its scheduling is powerful, its add-ons are many and the desktop app is free. The cost is time: you must make good cards yourself or find a good shared deck. See our Anki vs Quizlet comparison for detail.
StudyFetch, Mindgrasp and Knowt
These three share an idea: upload material, get study aids back. StudyFetch and Mindgrasp lean towards summaries, chat with your documents and generated quizzes. Knowt has a free tier and a flashcard-and-notes focus with a familiar feel for Quizlet users. Plans and limits change often, so check each one's pricing page before you commit.
NotebookLM
Google's NotebookLM is very good at one thing: answering questions from sources you supply and pointing back to them. It is a research and understanding tool more than a practice tool. Pair it with something that tests you.
ChatGPT
A general chatbot is the most flexible option and the easiest to misuse. It will explain anything, but it can state errors fluently, and reading its answers is passive. Use it to ask for quizzes and worked examples, and verify facts. We cover prompts that work in our guide to using ChatGPT for studying.
Brainscape and RemNote
Brainscape is built around rating how well you knew each card, which feeds its spaced repetition. RemNote puts notes and flashcards in one linked workspace, which suits people who already take structured notes. Both are flashcard-centred rather than course-centred.
How to choose
- You have a topic or a course book and no time to make materials: a course-building tool such as Type to Study.
- You want free, deep, long-term memorisation and don't mind setup: Anki.
- You want existing sets for a standard course: Quizlet or Knowt.
- You have many sources to understand and cite: NotebookLM.
- You want a patient explainer: ChatGPT, with checking.
- You like linking notes and cards: RemNote.
Whatever you pick, the method matters more than the app. Test yourself, space your reviews and use your own material. Combining two tools, for example NotebookLM to understand and Anki or Type to Study to practise, is perfectly reasonable.
