Can ChatGPT take notes from a lecture?

ChatGPT can take notes from a lecture you hand it, and cannot sit in the lecture hall for you. Upload a recording or paste a transcript, and it produces structured notes, key concepts, definitions, and practice questions on request.

The constraint is length: a 90-minute lecture usually exceeds upload limits, so recordings need splitting, and transcripts of long sessions may need chunked prompting. Multi-speaker seminars lose the speaker labels.

The student workflow that works: record the lecture with permission, transcribe it, then use ChatGPT on the text for summaries and exam prep. Check your institution's recording policy first; most allow personal study use, some require asking.

The recording half is what voice recording for students is built for.
