How to transcribe a lecture recording and turn it into notes

To go from a lecture recording to notes on a Mac, import the file into NoteOwl’s Transcripts screen: NoteOwl transcribes it on your Mac with the speakers labelled, then Summarize as → Student Lecture turns it into study notes — topics, definitions, examples and exam points.

Then ask the lecture questions and get answers that cite the passage. Importing recordings is part of NoteOwl Pro; for a lecture recorded in Voice Memos, Apple’s free transcript is an option too.

The top of an imported recording (an interview; a lecture file looks the same): length, speakers, file, and Summarize as.

Can AI answer questions about a lecture recording?

Yes, with NoteOwl Pro. Ask chat with your meetings a question and it answers only from your own imported and recorded lectures, citing the passage it used. It says so when nothing matches instead of guessing.

Press ⌘K to search every lecture at once. To record the next one yourself, in the room or online, see NoteOwl’s lecture recorder.

Questions you could ask a lecture

  • What did the lecturer say will be on the midterm?
  • How was the midpoint method explained?
  • Where did she work through the coffee cart example?
