AI note-taking for your lectures: how to turn a recording into complete notes

Taking notes by hand forces you to choose between writing and understanding. With AI, you can focus in class and still have everything that was covered in writing afterward. But only if you ask for it the right way.

What you need

The lecture recording

Made with permission from the professor and anyone else who speaks in it.

The slides or PDF

If there are any. They help get technical terms and formulas right.

Summary or complete notes: see for yourself

The same minute of a Biochemistry lecture, run through AI two different ways. Switch tabs to compare.

Summary · 4 lines

  • The Krebs cycle takes place in the mitochondria.
  • It produces NADH, FADH₂, and ATP.
  • Three molecules of CO₂ are released per turn.
  • It is regulated by several enzymes.

The result: the professor's example is gone, and the number that was hard to hear has been filled in with a made-up figure. Study this, and you're studying a mistake.

Notes · in order, nothing summarized

The Krebs cycle takes place in the mitochondrial matrix. It oxidizes acetyl-CoA and captures the energy as NADH and FADH₂, which then pass their electrons to the respiratory chain. The professor stresses that it produces very little ATP directly.

, three NADH, one FADH₂, and one GTP.

The result: everything that was covered is there, and nothing unclear gets guessed: it's flagged with its timestamp. Tap the underlined part.

Step by step

  1. Upload the audio and the slides together

    With both sources, the AI can check what was said against what was on screen.

  2. Ask for complete notes, not a summary

    A summary loses the examples and nuances your professor emphasized. You can always summarize later yourself.

  3. Keep the lecture's order

    Your notes should follow the flow of the lecture, with sections and the slides where they belong.

  4. Double-check anything unclear

    If a passage was hard to hear, check that minute of the audio instead of trusting whatever the AI filled in.

  5. Organize them by course and topic

    That way you can find them when it's time to study.

Common mistakes when taking notes with AI

Tap each mistake to see what to do instead.

MistakeUsing a generic chatbot and asking it to “write my notes”

It usually gives you a summary and fills gaps with information that never came up in your lecture. Instead: work from the recording and ask for all the content.

MistakeSkipping the slides

Names, numbers, and formulas are what gets garbled most when there's only audio. Instead: always upload the slides along with the recording.

MistakeStudying without reviewing

If a part that was hard to follow in class suddenly sounds perfect, be suspicious. Instead: listen to the flagged minutes before you study.

Notes checklist

Something's missing: your notes don't cover the whole lecture.

Your notes are complete. Now you can study with confidence.

How Bloopy does it

  • Upload your lecture audio and its slides, and in a few minutes you get complete notes, in order, nothing summarized.
  • It puts the slides and images right into the notes.
  • Anything that was hard to hear is flagged with its timestamp so you can check it.
  • You can edit them, organize them by course and topic, and study with flashcards and quizzes.
