How to Record a Lecture and Turn It into Notes with AI

Typing everything a lecturer says means listening to none of it. Recording the lecture lets you follow the argument in the room and leave the notes to afterwards. Here is how to record a class and turn it into notes, a transcript and a deck to revise from.

  1. Before the lecture: ask, then set up

    Check your institution's rules and ask the lecturer before recording; many allow it for personal study. Put the phone face-up near the front, or open NoteBase in the browser on your laptop, and allow the microphone once.

  2. During the lecture: record and listen

    Open the recorder in NoteBase and press record, and keep the app open while it runs. Write down only what the audio cannot carry - a diagram on the board, a page number - and spend the rest of the hour listening.

  3. After the lecture: get the notes

    Stop the recording and NoteBase transcribes it. The note comes back with a summary of the lecture, the key concepts, and the full transcript with a timestamp on every paragraph, so a point you missed is one click from the moment it was said.

    • A summary and key concepts on top
    • The full transcript, timestamped and searchable
    • Notes in your language, even if the lecture was not
  4. Before the exam: revise from it

    Open the note's tools and choose Exam Room to generate flashcards and a practice quiz from what was actually said in class. Ask the AI chat to explain a part again, or search across every lecture of the term at once.

Questions about this guide

Is it legal to record a lecture?

It depends on your institution and country. Ask the lecturer and check your university's policy; recording for personal study is often allowed with permission.

Can I record on my laptop instead of my phone?

Yes. The recorder works in the browser at notebaseapp.com as well as in the iPhone and Android apps.

What if I already have a recording?

Upload the audio file instead - MP3, M4A and WAV all work - and you get the same notes.
