The setup is straightforward: Gemini 3 plans the deck, and Nano Banana Pro paints each slide as a single image: layout, text, visuals, everything. No templates, no manual tweaking.
It’s an weekend experiment, so plenty of rough edges: inconsistent styles, no fine-grained editing, and bugs probably running around freely. But it works, and it's free to try.
If you have feedback, ideas, or want to roast the approach, I’d love to hear it. Just exploring whether this is worth taking further.
