## What this workflow gives you

### 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.

### 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.

## How BrainDen turns a lecture recording into study notes

1. **Confirm permission:** Before recording, make sure everyone knows about and agrees to it, and follow the rules of your location and institution.
2. **Record the lecture:** Keep BrainDen open with the visible recording indicator while the class or study session is in progress.
3. **Review and practise:** Check the transcript and structured note, add your own context, and move into flashcards, quizzes, or Explain It Back.

## Example: a physiology lecture

**Input:** A 55-minute class explaining cardiac output, stroke volume, preload, afterload, and compensatory responses.

**Possible output:**

- 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

## How to get a better result

### 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.

## 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.
