Stay present during the explanation
Use the recording as a safety net while you listen, participate, and note the points that matter most to you.
Audio study tools
Turn a lecture recording into notes while you focus on class
Capture the lecture, keep a visible recording indicator on screen, and let BrainDen transform the session into a structured note. You can retain the transcript for study and choose whether the original recording should remain after processing.
Free to start No card required Your material stays connected
Keep a usable transcript
Search and verify what was said without repeatedly moving through the full audio timeline.
Control the original recording
Choose whether BrainDen keeps or removes the audio after the note is generated while retaining the transcript.
From source to active study
How BrainDen turns a lecture recording into study notes
- 01
Confirm permission
Before recording, make sure everyone knows about and agrees to it, and follow the rules of your location and institution.
- 02
Record the lecture
Keep BrainDen open with the visible recording indicator while the class or study session is in progress.
- 03
Review and practise
Check the transcript and structured note, add your own context, and move into flashcards, quizzes, or Explain It Back.
A concrete example
Example: a physiology lecture
A 55-minute class explaining cardiac output, stroke volume, preload, afterload, and compensatory responses.
A useful result could include
- A structured note grouping definitions, relationships, and clinical examples
- A transcript for checking the lecturer's exact explanation
- Recall prompts connecting changes in preload or afterload to cardiac output
Generated material is a study aid. Review important terminology, notation, and claims against your source.
Make the result better
Use AI as the beginning of your study process
BrainDen removes repetitive setup work. Your judgement, course context, and retrieval practice are what turn the result into learning.
Ask before recording
Consent and recording requirements vary by jurisdiction and institution. BrainDen's prompt is a reminder, not a substitute for understanding those rules.
Add the visual context
Lecturers often point to slides, diagrams, or demonstrations. Add those details when they are essential to understanding the spoken explanation.
Review soon after class
Correct names, notation, and ambiguous passages while the context is still fresh in your memory.
Questions and answers
Frequently asked questions
Do I need permission to record a lecture?
Recording rules vary by location and institution. Make sure everyone knows about and agrees to the recording, and follow the applicable requirements before you begin.
Can BrainDen delete the recording after creating the note?
Yes. You can choose to remove the original audio after processing while keeping the transcript and generated note for study.
Can I turn the lecture into flashcards and quizzes?
Yes. Once the lecture note is ready, the same material can be studied with flashcards, quiz questions, a mind map, and Explain It Back.
What if the lecturer uses diagrams or slides?
Review the generated note and add any important visual information that the recording alone could not represent accurately.
