Show HN: Snapdeck – Generating presentation design, not templates

Thanks for checking out Snapdeck! I’m Minkyu, one of the founders (based in Seoul ).

One of the hardest things we faced was teaching LLMs visual composition — not just text. We had to build our own layout agent system that scores composition and color balance, and we’re experimenting with letting multiple agents “vote” on design quality.

If anyone here is curious about the architecture, dataset approach, or layout evaluation logic, I’d love to dive deeper — happy to share more technical details. Also, I’d really appreciate feedback from the HN design and ML folks on where this could go next.
