The best use of AI for study isn’t getting answers: it’s getting quizzed, getting explanations and spotting gaps. These free tools help you revise actively, and here’s how to stop them doing the learning for you.
Our top picks

How to get started
Upload one topic’s slides and notes to Gemini Notebook.
Ask for a 10-question quiz and answer it without looking.
For anything you got wrong, ask ChatGPT (study mode) or Claude to explain it step by step.
Make your own flashcards from the gaps and review them over several days.
How we chose
We picked free tools that support active revision: quizzing, explaining and checking understanding. We used official product and pricing pages; we haven’t benchmarked them on exam results.
Gemini Notebook: revision material from your own notes
Upload your lecture slides, readings and notes, and Gemini Notebook can make summaries, study guides, quizzes and audio overviews, pointing to where each answer came from. Because it works from your sources, it’s the safest way to generate practice questions that match your course.
ChatGPT, Claude and Gemini as tutors
General assistants are good at explaining concepts in different ways. ChatGPT’s free plan includes a study mode, designed for working through problems rather than just giving answers. Claude and Gemini are also free and handy for explanations. A good prompt: “I’m studying [topic] for [course]. Ask me one question at a time to test my understanding, wait for my answer, then explain what I got wrong.” Always check facts against your course materials: assistants can be confidently wrong.
Flashcards that actually work
Research on learning consistently supports retrieval practice (testing yourself) and spacing (reviewing over days, not cramming). AI can draft flashcards, but making them yourself from the questions you got wrong is part of the learning. Free spaced-repetition apps such as Anki (opens in new tab) handle the scheduling.
Summaries: useful, with care
QuillBot (opens in new tab) (paid link: we may earn a commission)’s summariser can condense a long reading so you can check you caught the main points. Read first, summarise second: a summary of something you haven’t read won’t help you in an exam. For academic writing help, see Jenni AI (opens in new tab) (paid link: we may earn a commission) and our best AI essay writing tools.
Academic integrity first
Every school and university sets its own rules on AI, and they change often. Before using any tool for assessed work, read your course or unit AI policy, note what must be declared, and ask your teacher or lecturer if you’re unsure. Use AI to understand and organise, not to produce work you submit as your own. Australian students can also look at guidance from their institution and from TEQSA, the higher-education regulator.
Privacy and accounts
Many AI tools need an account, and some features are only for people aged 18 and over. Check the age rules before signing up, and use your school account only for tools your school has approved. Don’t upload other students’ personal information, recordings of people who haven’t agreed, or material you don’t have permission to share.
Our verdict
Use Gemini Notebook to quiz yourself on your own notes, ChatGPT (study mode), Claude or Gemini for explanations, and QuillBot to condense readings you’ve already done. Test yourself, space your reviews and check facts. See also the best free AI note-taking tools for students.
Frequently asked questions
What is the best free AI study tool?
Gemini Notebook, because it makes quizzes and study guides from your own notes and shows where answers came from. ChatGPT, Claude and Gemini are good free tutors.
Can AI make flashcards for me?
Yes, but making your own from the questions you got wrong helps you learn. Free apps like Anki handle spaced review.
Does ChatGPT have a study mode?
Yes. ChatGPT’s pricing page lists study mode on the free plan as well as paid plans.
Is it cheating to study with AI?
Using AI to quiz yourself and explain concepts is usually fine. Submitting AI-written work as your own usually isn’t. Check your course rules.
Can I trust AI explanations?
Not blindly. Assistants can be confidently wrong, so check against your course materials, especially for formulas, dates and definitions.
