How to summarize a recorded lecture with AI, step by step

Recording lectures is great, but a recording alone doesn't help much: nobody has time to relisten to ten hours of class the week before an exam. What works is turning each recording into concise notes and review material. Here's how to do it with AI in a few minutes.

Step 1: record the lecture well

Ask your instructor first (many schools require it, and most instructors say yes for personal study). Sit near the front, leave your phone on the desk with the screen on and check the microphone isn't covered.

You can record directly in SwiftBOL from your phone or laptop browser, or use your phone's recorder and upload the file afterwards.

Step 2: pick Student mode and a style

In SwiftBOL, choose Student mode and an output style: class notes by topic, an outline, exam questions or flashcards. If the subject has tricky terms (names, formulas, technical vocabulary), add them to your glossary so they're spelled right.

Step 3: review the summary by chapter

A few minutes later the lecture is split into chapters, each with its exact minute. If a part isn't clear, tap the timestamp and listen to just that bit instead of the whole class.

The “Ask your audio” chat lets you ask things like “what example did she use to explain elasticity?” or “did he say anything about the exam?”, and answers from what was said in that specific lecture.

Step 4: turn the summary into study material

From “Create with AI” you can generate a scored practice test, flashcards for definitions, an outline or a glossary. Studying by answering questions (active recall) sticks far better than rereading notes, and here the questions come from your own lecture, not a generic syllabus.

If you study with classmates, share the session with a link: they can see the summary and take the quiz without creating an account.

How much time it saves

Cleaning up notes from a one-hour lecture usually takes another hour or more. With AI, the summary is ready in minutes and your time goes where it matters: understanding and reviewing. The Free plan gives you 2 hours of audio a month to try it with this week's classes.

Try it with your own audio

SwiftBOL transcribes, summarizes, and structures your meetings and classes in minutes. The Free plan includes 2 hours of audio a month, no credit card required.
