Yes. AI is now a useful study partner if you use it to learn rather than to hand in its work. For most students we recommend ChatGPT's free plan with study mode turned on, which guides you through problems step by step. US college students should also claim Google's free year of Google AI Pro before December 31, 2026, and use Gemini Notebook to study from their own class materials.
A 2025 HEPI and Kortext survey found 92% of UK undergraduates used AI tools, up from 66% a year earlier.- Our pickChatGPTFree; paid plans available

ChatGPT
Best for most students who want a free tutor that explains, quizzes and helps them plan.
ChatGPT's free plan includes unlimited text chats with OpenAI's current model, subject to abuse guardrails, plus limited uploads, image creation, voice chats, deep research and memory ChatGPT pricing ↗. For a student, the unlimited chat is what matters: you can ask follow up questions until a topic makes sense.
The feature that makes it our pick for studying is study mode. OpenAI launched it on July 29, 2025, and it is designed to help you work through problems step by step instead of just giving an answer ChatGPT study mode ↗. It asks guiding questions, offers hints, breaks material into short sections, adjusts to your level and checks what you remember with quizzes and open questions ChatGPT study mode ↗. You turn it on by choosing Study and learn in the tools menu ChatGPT study mode ↗. OpenAI's pricing table lists study mode on Free, Go, Plus and Pro ChatGPT pricing ↗.
The free plan's limits on uploads and deep research are not given as numbers ChatGPT pricing ↗, and OpenAI notes the paid Go plan may include ads ChatGPT pricing ↗. ChatGPT can be wrong, so check facts against your course materials. Hands on testing is in progress; we will update this guide with results.
Why we like it
- Unlimited text chats on the free plan
- Study mode teaches step by step with hints and quizzes
- Works on web, phone and desktop
- Good for planning essays, outlines and study schedules
Flaws but not dealbreakers
- Upload and research limits on Free are not published

- Easy to misuse for graded work
Gemini Notebook (formerly NotebookLM)
Best for studying from your own lecture slides, readings and notes.
Gemini Notebook, formerly known as NotebookLM, works only from the sources you add, such as readings, slides and notes Android Authority ↗. That makes it better than a general chatbot for exam prep, because answers come from your course rather than the open web. Each notebook is separate, so keep one per class Gemini Notebook help ↗.
In September 2026 Google announced Learning Overviews that combine summaries, infographics, quizzes and flashcards, new quiz formats including short answer and fill in the blank, 60 second video overviews in more than 80 languages, and an English only mobile audio recorder for lectures Android Authority ↗.
It is free with standard limits that refresh every 5 hours up to a weekly cap Gemini Notebook limits ↗. Google does not publish the standard limit as a number; AI Plus doubles it and AI Pro quadruples it Gemini Notebook limits ↗.
Why we like it
- Answers from your own class materials
- Builds quizzes, flashcards and summaries
- Free to use
- Lecture audio recorder on mobile
Flaws but not dealbreakers

Who this is for
This guide is for high school and college students, adult learners and parents choosing tools for older kids. Google's student offer requires age 18 Gemini for students ↗, and younger children should use tools their school provides and approves.
AI use is already normal among students. In the HEPI and Kortext survey of 1,041 UK undergraduates, published in February 2025, 92% used AI tools and 88% used generative AI for assessments HEPI survey ↗. The top uses were explaining ideas, summarizing readings and brainstorming research topics HEPI survey ↗. Our picks cover those jobs plus writing and lecture notes.
Why you should trust us
We read each vendor's pricing pages, help articles and student offers and checked every price on October 9, 2026. We used the HEPI survey for how students actually use AI HEPI survey ↗. Every fact links to its source.
We have not yet tested these tools hands on for this guide. Hands on testing is in progress, and we will update this page with sample study sessions. No vendor paid for placement, and our picks were chosen on merit.
How we picked
We focused on tools that help you learn, not tools that write assignments for you. We ranked them on cost first, because most students pay out of pocket, then on study features and honesty about limits.
- A free plan that is useful on its own, or a real student discount
- Learning features such as guided explanations, quizzes and flashcards
- Works with your own class materials
- Clear, published limits and renewal terms
- Helps you write better without writing for you
What AI study tools can and can't do today
AI tools can explain a concept in several ways until it clicks, quiz you, make flashcards from your notes, summarize long readings and transcribe lectures. Study mode in ChatGPT is built to ask questions and give hints rather than answers ChatGPT study mode ↗, and Gemini Notebook builds quizzes and flashcards from your sources Android Authority ↗.
They still make mistakes. In the HEPI survey, 51% of students said getting false results put them off using AI, and 53% worried about being accused of cheating HEPI survey ↗. A chatbot can invent a citation or misread a chart. Always check facts against your textbook or lecture notes, and treat AI summaries as a starting point.
AI also cannot learn for you. If you paste in a question and copy out the answer, you will not remember it at exam time. Use the tutoring features, not just the answer box.
A simple AI study setup that costs nothing
You do not need five subscriptions. A good free setup uses three tools, each for a different job, and all of them have free plans ChatGPT pricing ↗ Gemini Notebook limits ↗ Grammarly plans ↗.
Start each unit in Gemini Notebook. Create one notebook per class and add the syllabus, slides and assigned readings. Ask it for a summary of each week, then generate a quiz before you read the summary again. Because it answers only from your sources, it is less likely to drift into material your course does not cover Android Authority ↗ Gemini Notebook help ↗.
Use ChatGPT with study mode when you are stuck. Paste in the problem, say what you have tried and ask it to guide you without giving the answer. Study mode is built to ask questions and give hints ChatGPT study mode ↗, which is closer to working with a tutor than reading a solution.
Write your own drafts, then run them through Grammarly's free plan for grammar and tone Grammarly plans ↗. If your course allows AI feedback, ask ChatGPT what your argument is missing rather than asking it to rewrite the essay. Save your drafts and notes, so you can show your process if anyone questions your work.
If you record lectures, Otter's free 300 minutes a month covers several hours of classes, though each recording stops at 30 minutes on the free plan Otter pricing ↗. Add the transcript to your Gemini Notebook for that class so your quizzes include what was said in the room.
- Gemini Notebook: one notebook per class, quizzes before exams
- ChatGPT study mode: hints when you are stuck
- Grammarly Free: clean up your own writing
- Otter Basic: lecture transcripts, with permission
Before you sign up
Read your school's AI policy and each syllabus. Rules vary by course: one professor may allow AI brainstorming while another bans it. When AI use is allowed, many schools expect you to say how you used it.
Watch free trials. Google's student offer needs a payment method and renews at $19.99 a month Gemini for students ↗, and Grammarly Pro starts with a 7 day trial Grammarly plans ↗. Cancel before the renewal date if you do not want to pay.
- Check your course's AI policy before using AI on graded work
- Keep notes on how you used AI in case you need to explain it
- Do not upload other students' work or private data
- Ask before recording lectures
- Set reminders before trials and free years end
- Use your .edu email for student discounts, such as Otter's 20% off Otter pricing ↗
What to look forward to
Study features are spreading fast. Google added Learning Overviews, new quiz types and short video overviews to Gemini Notebook in September 2026 Android Authority ↗, and Perplexity sells an Education Pro plan with a Learn Mode for verified students Perplexity plans ↗. Expect more tools that quiz and coach rather than answer. We will update this guide as student offers change.
