Anyone who has asked Gemini Notebook for a real lecture deck knows the feeling. The slides it makes are genuinely beautiful — clean layouts, sensible structure, your own sources turned into something you would happily show a room. And then you count them. Twenty-ish. You asked for forty-five.
Ask again, ask more firmly, ask in a different way — the deck still comes back short, or trails off, or loses its shape somewhere in the middle. And even when the content is right, presenting it never quite is: the slides live in a small scroll view, with a watermark sitting in the corner of every frame.
The ceiling everyone quietly hits
Gemini Notebook's slide generator simply has a comfort zone, and long-form teaching lives outside it. A full lecture, a training module, a conference talk with proper depth — these want 35, 45, 50 slides. The generator wants to stop well before that. For months, the workarounds were all bad: split your topic into several small decks and shuffle between them live, or export everything and rebuild it by hand in PowerPoint. Both defeat the point of generating slides in the first place.
Ask big: Extended and Extra-long
The first half of the answer lives in Studio Recipes. When you run the Presentation recipe, the length selector now goes well past the usual sizes: Extended (30–40 slides) and Extra-long (44–50 slides).
Pick one, run it, and the deck that arrives actually matches what you asked for — the slide count lands close to your request, every slide carries real detail rather than thinning out toward the end, and the whole thing keeps one design language: the same theme, colors, and layout from the first slide to the last. There is machinery under the hood making that happen, but you never have to see it, tune it, or think about it. You pick a length; the deck arrives.
One show, no seams
The second half is Premium Deck View. Press Present on a long deck and it plays as one continuous presentation. If the deck was generated in parts, the parts are detected automatically and flow together under a single slide counter, with a small Part badge so you always know where you are. You press Next; the show just keeps going.
No exiting one deck to open another. No manual file merging before your talk. And because it is Premium Deck View, no Gemini Notebook watermark anywhere in the frame — just your slides, full-screen, under your keyboard control.

Gemini Notebook has always been able to make good slides. Now it can make enough of them — and you can stand up and present the whole thing, end to end, without the seams ever showing.
