Present it live

Presentation mode turns any diagram into a live talk: the audience sees the diagram full screen and you advance it one step at a time while you speak.

Write speaker notes for each step: in the editor, select a step and fill in Speaker notes, or add "notes" to the step in the JSON. They’re never shown in the diagram.
```
{ "show": ["e2"], "flow": "e2", "caption": "The gateway asks the bank", "notes": "Mention that this call usually takes under 300 ms." }
```
Press Present in the editor (or in a shared diagram’s viewer). A window opens for the audience.
Press N to open your notes in a second window, and drag it to your laptop screen. Press F for full screen on the projector.

Your notes window

The presenter window shows the notes for the current step in large type, what the audience is reading now, what comes next, a small preview of the diagram and a timer. It has its own Previous and Next buttons.

The two windows stay in sync: you can advance from either one.

The closing screen

After the last step, advancing once more shows the audience a closing screen with “Thank you” and the diagram’s title. Press ← to go back to the diagram.
