Duply
What if your AI never had to guess your design again?
Real-world design systems documented as ready-to-use DESIGN.md files and agent prompts. Pick a design you love. Copy one file. Your AI agent builds in that visual language.
Hey Product Hunt,
I’m building Duply because AI coding tools are getting good at generating structure, but they still guess way too much when it comes to visual direction.
Duply is a library of real-world design systems packaged as ready-to-use DESIGN.md files and agent prompts. Instead of writing endless styling instructions, you pick a reference, copy one file into your AI coding workflow, and give the agent clear rules for typography, spacing, colors, components, layout, and interface feel.
The goal is simple: make AI-built websites and SaaS products feel less random, less generic, and closer to a real product from the first prompt.
GWould be great to hear what you think, especially if you’ve felt the same gap when building with AI agents.
Picked a brutalist design and copied the file into my project, the agent picked up the spacing and type scale right away without extra prompting. Wish the gallery had filtering by industry, but the prompt handoff is genuinely useful.
Picked a brutalist design and dropped the DESIGN.md into my agent, the output matched the vibe almost exactly which saved me an afternoon of fiddling. Wish there were more dark mode options but solid idea.
Having a live preview alongside each DESIGN.md would be huge. Something like a side-by-side rendered component so I can see exactly how spacing, typography, and colors translate before pasting the file into my project. Would save a ton of trial and error when comparing options.
Would love to see a live preview pane next to each design so I can see how the system renders before committing to it. Also helpful would be a small badge showing which frameworks or AI agents each DESIGN.md has been tested with.
Love this idea, a design md you can drop straight into a project is such a time saver. One thing that would make it even better: let users preview the design system on a live sandbox page before copying, so you can see spacing, typography, and colors rendered before committing.
Would love to see a way to preview the design system in a live sandbox before pulling the file into my own project, so I can quickly check spacing and typography. A small iframe playground per listing would make choosing the right system way easier.
