1. NotebookLM: the best AI study partner for your own notes
NotebookLM from Google is the tool most students wish they had found earlier. You upload your lecture slides, PDFs, notes, web links or YouTube videos, and it builds a private study space from them. Then you can ask questions and it answers only from your sources, with numbered citations that show exactly where each fact came from.
What you get for free: enough notebooks and uploads for a full semester, a generous number of questions each day, and handy extras such as study guides, flashcards, quizzes and mind maps. Its standout feature is Audio Overview: two AI voices talk through your material like a short radio show, perfect for revising on the bus.
How to use it well: create one notebook per subject. After each lecture, add the new slides and ask for “the five ideas most likely to come up in an exam, with a question for each.” Before a test, generate a quiz and try it without looking at your notes.
Watch out for: it is only as good as the files you give it. If your notes are wrong or incomplete, so are its answers.
2. ChatGPT Study Mode: a tutor that makes you think
The free version of ChatGPT includes Study Mode. OpenAI describes Study Mode as a way to build real understanding. Instead of handing you the answer, it asks what you already know, breaks the topic into small steps and checks your understanding with questions along the way.
How to use it well: turn on Study Mode from the tools menu and say what you are studying and your level, for example “first year economics, I keep mixing up demand and quantity demanded.” Ask it to quiz you at the end of each session.
Watch out for: the free plan has message limits that reset over time, and it can still make mistakes, especially with recent events or very specific facts. Check important points in your textbook.
3. Gemini Guided Learning: great for visual learners
Google Gemini’s free plan has a similar mode called Guided Learning. It explains topics step by step and can add images, diagrams and videos to help ideas click. If you already use Google Docs, Gmail or Drive for school, Gemini fits in nicely.
Student tip: Google has run discounts on its paid AI plan for students in many countries. Offers change often, so check the Google One student page before you pay for anything.
4. Claude: clear explanations and a learning mode
Claude from Anthropic is known for clear, careful writing and long, detailed explanations. Its free plan includes a learning mode that, like the tools above, guides you with questions rather than doing the work for you. It is especially good for understanding long readings and for feedback on the structure of your essays.
How to use it well: paste a paragraph of your own essay and ask, “Point out where my argument is weak, but do not rewrite it for me.”
5. Perplexity: research with sources you can check
Perplexity works like a search engine that writes a short answer and lists its sources right under it. That makes it a strong starting point for research, because you can open each link and decide whether the source is good enough for your assignment.
What you get for free: unlimited quick searches with citations and a small number of deeper searches.
How to use it well: use it to find good sources, then read and cite the original pages yourself. Never cite Perplexity itself in an assignment.
6. Elicit and Consensus: find real research papers
For university projects you often need peer reviewed papers, not blog posts. Elicit searches a huge library of academic papers and gives short summaries of each. Consensus answers yes or no style research questions, such as “Does sleep affect memory?”, by showing what published studies found.
Both have free plans with limits on their more advanced features, which is usually enough for a term paper. Always open the full paper before you quote it.
7. Google Lens: snap a problem, get step by step help
Stuck on a maths, physics or chemistry question? Open Google Lens in the Google app, point your camera at the problem and choose the homework option. It shows step by step solutions and links to explanations. On many Android phones, Circle to Search does the same: hold the home button and circle the question on your screen.
How to use it well: cover the answer, try the next step yourself, then check. Copying steps you do not understand will not help you in the exam hall.

8. Grammarly free: polish your writing
The free version of Grammarly checks spelling, grammar, punctuation and tone in your browser, Google Docs and email. It fixes mistakes without changing your ideas, which keeps your work yours.
Watch out for: some schools treat full AI rewriting as cheating. Grammar fixes are usually fine, but check your school’s rules before using any “rewrite” feature.
9. Gamma and Canva: presentations in minutes
Gamma turns a short outline into a full slide deck with layouts and images. Its free plan gives you a set number of credits, enough for several presentations. Canva has a huge free library of templates plus AI design tools, and Canva for Education is free for verified school students and teachers in many countries.
How to use it well: write your own outline first, let the tool design the slides, then edit every slide so it sounds like you. For more options, see our list of AI tools for PPT.
10. Otter: never miss a lecture note again
Otter records lectures and online classes and turns them into searchable text with a short summary. The free plan includes a monthly allowance of transcription minutes, which covers a good number of classes.
Watch out for: always ask your teacher before recording a class. Some universities have rules about recording lectures.
11. A local AI model: private study with no internet
If you study in places with weak internet, or you do not want your notes stored on a company’s servers, you can run a free AI model on your own laptop with apps like LM Studio or Ollama. It works offline and has no daily limits. Our step by step guide on how to run AI locally shows you how, even on a 16GB laptop.
How to use free AI tools for students without cheating
Most schools now have AI rules, and many teachers can spot work that was not written by the student. These habits keep you safe and help you actually learn:
- Read your school’s AI policy. Some courses allow AI for brainstorming but not for writing.
- Use AI to learn, not to submit. Ask it to explain, quiz and give feedback. Write the final work yourself.
- Check every fact. AI tools can invent quotes, dates and even fake sources. Look everything up in a trusted book or paper.
- Be honest. If you used AI for a part of the work, say so when your teacher asks.
- Keep your drafts. Saved drafts and notes show your own thinking if anyone questions your work.
7 study prompts that work in any AI tool
- “Explain [topic] like I am 12, then again at university level.”
- “Make 10 flashcards from these notes, question on the front, short answer on the back.”
- “Quiz me on [chapter] one question at a time and tell me why I got each wrong.”
- “Give me a 5 day study plan for my exam on [subject], 1 hour a day.”
- “What are the three most common mistakes students make with [topic]?”
- “Here is my essay outline. What is missing, and which point is weakest?”
- “Turn this long reading into a one page summary with the key terms in bold.”
Protect your privacy
- Do not paste personal details, passwords or other students’ work into AI tools.
- Turn off the setting that lets companies use your chats to train their AI. Our guide to the AI training opt out shows where to find it in each app.
- Use your school account where your school provides one, since school versions often come with stronger privacy promises.
