This is a complete presentation authoring system that generates static HTML slide decks with 36 themes, 31 layouts, and 27 animations. What makes it worth attention is the presenter mode: hit S and you get a magnetic popup with pixel-perfect previews of current and next slides, a scrollable speaker script panel, and a timer. The previews use iframes with the actual deck CSS so colors and fonts match exactly what the audience sees. It's designed for technical talks and 小红书 posts but works for pitch decks and reports too. If you've ever fumbled through a presentation with notes on paper or a second laptop, the presenter window alone justifies keeping this around. The templates are opinionated and the keyboard shortcuts are discoverable, which beats starting from a blank reveal.js fork every time.
