The canvas is the deck
Presentation mode in sket is not an export format. Scenes are saved camera moves over the living document — so your slides can never go stale.
Here is the life cycle of most architecture diagrams: drawn with care, exported to PNG, pasted into a slide deck, and then — silence. The system keeps evolving; the picture in the deck does not. Six months later it's actively lying to new hires.
The export step is the murder weapon. So we removed it.
Scenes are camera moves
In sket, a presentation is a sequence of scenes: saved viewport positions over the one true canvas. Each scene carries markdown speaker notes; the leading heading becomes the scene title while presenting. Hit play and the camera glides between them.
Because a scene is just a camera position, "updating the deck" is not a task that exists. You edit the diagram. The deck is the diagram.
Notes that stay backstage
Speaker notes live as pins on the canvas that only reveal themselves during play mode, when the presenter presses them — like flipping a cue card. Your audience sees a clean canvas; you see your script.
The embedded diagrams on this blog use the same machinery, plus one trick the app will get soon: press the speaker icon and the Web Speech API reads the scene notes aloud. The diagram literally presents itself — a small preview of the AI presenter avatar on our roadmap.
Build your next talk in the canvas: draw it once, present it forever.
