AI can help you capture lectures, organize notes and turn them into study material — but notes you never process yourself won't help much on exam day. The goal is to use AI for the busywork (transcribing, organizing, generating practice questions) while you do the thinking. This guide shows a note-taking workflow for college and adult students and compares the tools that help.
Check your course's AI policy first. Check your school's and instructor's recording policy before recording any class, and don't share recordings or AI summaries of course materials without permission. AI transcripts and summaries contain errors, so always check them against your slides and readings.
How to Take Notes with AI, Step by Step
1
Pick one home for your notes
Choose one app for every class — Notion for an organized workspace with tasks, or Obsidian for private notes stored on your device — and create a page or folder for each course.
2
Prepare before class
Skim the slides or reading and write down the main topics and any questions, so you know what to listen for.
3
Take notes in your own words
Write key ideas, examples and anything the instructor emphasizes in your own words. Summarizing as you go helps you remember more than typing everything.
4
Capture the lecture if allowed
With permission, record with Otter.ai or use the instructor's posted recording, so you can fill in gaps later.
5
Clean up within a day
Compare your notes with the transcript or slides, fix errors, and add anything you missed while it's fresh.
6
Ask questions about your materials
Upload your notes, slides and readings to Gemini Notebook and ask it to explain confusing parts, with citations back to your sources.
7
Turn notes into active recall
Generate flashcards or a practice quiz from your corrected notes and test yourself over several days instead of rereading.
Recommended AI Note-Taking Tools

#1
Notion
Best for: an organized home for every class's notes and deadlines
Notion is a flexible workspace for notes, class pages and to-do lists. Students and educators can get the Plus plan free by signing up with a school email address. Notion's AI Meeting Notes, which transcribe and summarize conversations, are included on the Business plan ($20 per member per month); the Free and Plus plans include only a trial of AI features.
Why students use it:
Free Plus plan for students with a school email
Keeps notes, readings and deadlines for every class in one place
Templates for course dashboards and study schedules
Downside: Full AI features like Meeting Notes require the paid Business plan, and building a good setup takes time.
#2
Gemini Notebook (formerly NotebookLM)
Best for: asking questions about your notes, slides and recordings for free
Google's Gemini Notebook, previously called NotebookLM, lets you upload lecture audio (MP3, WAV, M4A and other formats), PDFs, slides and YouTube links, then answers questions using only those sources and links back to where each answer came from. It can create study guides, flashcards, quizzes and audio overviews. Free users can add up to 50 sources per notebook, each up to 200MB.
Why students use it:
Free and works with recordings, slides and readings together
Answers cite your own course materials
Built-in flashcards, quizzes and study guides
Downside: It doesn't record live, so you need an audio file or posted recording first. It only knows what you upload.
#3
Otter.ai
Best for: recording and transcribing lectures you're allowed to record
Otter.ai records and transcribes audio in real time, then generates an automatic summary you can search and ask questions about. The free Basic plan includes 300 transcription minutes per month but caps each recording at 30 minutes and allows 3 file imports total. Pro includes 1,200 minutes per month, recordings up to 90 minutes and 10 imports per month for $16.99/month or $8.33/month billed annually, and students with a .edu email get 20% off Pro.
Why students use it:
Live transcript you can follow and highlight during class
Automatic summaries and searchable notes after each recording
20% student discount on Pro with a .edu email
Downside: The free plan's 30-minute limit per recording cuts off most full lectures, and it's built mainly for meetings. Accuracy drops with poor audio or heavy technical vocabulary.
#4
Obsidian
Best for: private, offline notes you link across classes
Obsidian is a note-taking app that stores your notes as plain Markdown files on your own device, so they work offline and stay yours. You can link notes together and see the connections in a graph view, and thousands of community plugins add extra features. The app is free without limits and doesn't require an account. Optional Obsidian Sync costs $4/month billed annually ($5 monthly) and Obsidian Publish costs $8/month billed annually ($10 monthly); students and faculty get 40% off Sync and Publish.
Why students use it:
Free with no limits or account required
Notes are plain files you own, and work offline
Linked notes and graph view for connecting ideas
40% student discount on Sync and Publish
Downside: There's no built-in AI (only community plugins), syncing across devices costs extra unless you set up your own method, and real-time collaboration isn't its strength — it takes time to set up the way you like.
Frequently Asked Questions
Tools like Otter.ai can record and transcribe a lecture and write a summary, but only record when your school and instructor allow it. Notes you write and review yourself help you learn more, so use AI to fill gaps rather than replace note-taking.
Gemini Notebook is free for asking questions about your notes, slides and recordings. Notion's Plus plan is free for students with an eligible school email, Obsidian is free, and Otter.ai has a free plan with a 30-minute limit per recording.
Notion is better if you want notes, assignments and group projects in one organized workspace. Obsidian is better if you want private notes stored on your own device that you link together over time.
It depends on your school's policy, your instructor and local recording laws. Many colleges require instructor permission. Students who need recordings for a disability can request them as an accommodation.
Not always. Transcripts often garble names, formulas and technical terms, and summaries can miss what your instructor emphasized. Check AI notes against your slides and readings before you study from them.
