How to study from lecture recordings with ChatGPT or Claude

Why ChatGPT and Claude need transcripts first

Both assistants work from text, and neither takes a semester of lecture audio. As of November 13, 2026:

• Claude's chat uploads take documents and images, such as PDF, DOCX and TXT files. Audio isn't on Anthropic's list of supported files.
• ChatGPT's audio uploads need a paid plan, and a recording in Chat can be up to 6 minutes long. An MP4 that ChatGPT identifies as video isn't supported.

A single 75-minute lecture is too long for ChatGPT's audio uploads and can't go into Claude at all, and 40 hours of class is 2,400 minutes. With transcripts, both assistants can read every lecture, and Wave AI's connector lets them search all of your transcripts at once instead of one file at a time.

Step 1: Record every class, or import the ones you have

• In the lecture hall: tap record in Wave AI on iPhone or Android, or start it from an Apple Watch or Wear OS watch.
• Online classes: Wave's calendar bot joins scheduled Zoom, Google Meet and Microsoft Teams classes, or the Wave AI app for Mac and Windows records the class with no bot.
• Recordings you already have: Wave Pro imports audio (MP3, M4A, WAV and most formats a phone makes) and video (MP4, MOV and WebM), up to 10 hours per file. Processing runs on Wave's servers, so you can close the app once the upload finishes.

Keep one folder per course and put the course name in each session's title, so the assistant searches the right classes. Claude can rename sessions and file them into folders for you. Before you record, check your school's and your professor's recording policy.

Step 2: Connect Wave AI to Claude or ChatGPT

• Claude: on a computer, add Wave AI Note Taker from Claude's connector directory. It works on Claude's free plan, and it's then in the Claude app on your phone too. Details: Wave AI for Claude.
• ChatGPT: install Wave AI Note Taker from the ChatGPT app directory, then type @Wave in a chat. Details: Wave AI for ChatGPT.

You connect once, and every class you record after that is there when you ask.

Step 3: Ask what the professor said

Name the course, a date or a topic so the assistant searches the right lectures, and ask for quotes so you can check them.

What did Professor Ruiz say about consideration in contracts? Quote her and give the date of each lecture.

Search my Contracts folder for every time the professor said something would be on the exam.

Explain promissory estoppel the way it was explained in class on October 3, then give me two practice questions on it.

Which topics came up in more than one lecture this month?

Check anything you'll rely on against the transcript, especially names, numbers and dates.

Step 4: Turn it into exam notes

Ask for one study guide per unit, with key terms as the professor defined them, the examples used in class, and the date of each lecture it drew on. Then ask for practice questions built only from what was said in class, each with its answer and the lecture it came from. For a printable page, paste a transcript into Wave's free Cornell notes generator. Keep a lecture date on every note so you can go back to the transcript when something looks off.

Worked example: 40 hours of lectures, finals in 3 weeks

Say you're taking four courses and have about 10 hours of recorded lectures for each, saved on your phone or laptop.

The cost: Wave AI Free covers 30 minutes a month, so 40 hours (2,400 minutes) would take 80 months on the free plan. Wave Pro covers it, because file import is part of Pro and recording is unlimited.

If you only need it for finals, one month of Pro on the web is $15. If you'll record every class from now on, Pro is $80 a year on the web, which works out to $6.67 a month (the App Store and Google Play charge $100 a year). Move back to Free after finals and the recordings and transcripts you already have stay in your account.

• Week 1: Import the files, one course at a time, and connect Wave AI to Claude or ChatGPT. Split any file longer than 10 hours, because Wave cuts it off there. Wave also caps imports per day: 20 a day until your plan has billed for the first time (8 a day in an account's first 48 hours), then 100 a day. Before that first payment, spread 30-odd files over a few days.
• Week 2: Go course by course. Ask for a study guide for each unit and practice questions from what was said in class.
• Week 3: Find the gaps. Paste your study guide into the chat, ask which lecture topics it leaves out, and quiz yourself on those. Check every quote you plan to use against the transcript.

Wave AI or Gemini Notebook (formerly NotebookLM)?

Google renamed NotebookLM to Gemini Notebook on July 16, 2026. It's a study tool built around sources you add, and for some students it's the better pick. This comparison comes from each product's own pages, checked on November 13, 2026.

Gemini Notebook is the better pick if you want flashcards and quizzes built in, or if most of your material is readings, slides and PDFs. US college students can also claim a free year of Google AI Pro until December 31, 2026, which raises Gemini Notebook's usage limits.

Choose Wave AI when you record classes longer than an hour on your phone or watch and want to keep the recording with a speaker-labeled transcript. It also fits if you already study in Claude or ChatGPT, or record meetings and calls as well as lectures.

You can use both. Export a lecture's transcript from Wave AI as a PDF (Pro) and add it to a notebook as a source.
