1. Enable camera & mic. 2. Say something and watch the Mic bar move — if it doesn't, the take will be silent.
3. Hit Record. 4. Advance the board with Next (or the → key) while you talk.
5. Stop → Download a finished 9:16 reel. One take, no editing. Draw: pick Pen or Highlight and mark straight on the frame while you talk — it records.
Marks are kept per slide, so Next wipes the screen and Prev brings them back.
Keys: P pen · H highlight · Z undo · X clear.
