Putting the tools together for an exam
You can use several of these tools in one exam review session. Add the assigned slides and readings to Gemini Notebook and make a study guide based on your course. Take questions you cannot explain to ChatGPT Study Mode or Gemini Guided Learning, where you can work through an example and answer follow-up questions.
Turn the details you keep missing into a Knowt or RemNote flashcard deck and review them over several days. For a problem-based course, use Photomath to find an error in a worked solution, then attempt a similar question from scratch.
FAQs
Is using AI to study considered cheating?
Using AI to explain a concept, generate practice questions, or help you review your own notes is a common way to study. Rules for graded homework, essays, and take-home exams vary by course. Follow your instructor’s policy on AI assistance and disclosure before submitting work.
How can I check whether an AI study answer is correct?
For class readings, follow the citations in Gemini Notebook or Adobe Student Spaces and compare the answer with the original passage. For web research, open the articles or datasets linked by Perplexity. For math, check the steps against your own solution and identify where the two calculations differ.
How can I use AI for active recall?
Ask ChatGPT Study Mode or Gemini Guided Learning to quiz you one question at a time. Keep your notes closed, answer from memory, and request feedback before the next question. When you miss a concept, ask for another question that tests the same idea in a different way, and try it again the next day.
Can I use AI study tools without uploading class notes?
Yes. Start ChatGPT Study Mode or Gemini Guided Learning with a question you type. Photomath accepts an equation entered in its calculator, Perplexity searches published web sources, and Knowt lets you build flashcards manually or study an existing public deck.
Can I move my notes and flashcards to another app?
Some study materials have portable exports. RemNote exports notes as Markdown and flashcards as Anki packages, and Knowt can save flashcard sets as PDFs. Gemini Notebook exports reports to Google Docs and tables to Google Sheets. Napkin AI exports diagrams as PNGs or PDFs, and Otter Basic can save transcripts as TXT files.
Which free AI study tools work on a phone?
ChatGPT, Gemini, Knowt, RemNote, Otter, Photomath, and Gemini Notebook have mobile access. Adobe Student Spaces works in a mobile browser. Some Gemini Notebook features have fewer controls on mobile, and creating Napkin AI diagrams requires a computer.
Can high school students use these AI study tools?
Knowt generally allows users ages 13 and older, with verified parent or guardian consent for AI features used by anyone under 18. Adobe Student Spaces is designed for students ages 18 and older. Access through a school-managed Google account is set by the school.
