Dropping a DESIGN.md file into my Claude Code workspace instantly stopped the AI from inventing hideous random UI styles. Huge time saver.
Great selection of reference design systems, though I wish there were more niche SaaS templates included.
Clever workaround for AI hallucinating weird padding and colors.
clean setup
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Browse documented design systems from real products and copy the one you want as a single portable file.
Files are written in language and structure that AI coding agents can follow directly, covering typography, spacing, color and components.
Beyond static tokens, each write-up describes layout patterns, interaction rhythm and the overall visual direction of a product.
Works with Claude Code, Cursor, Codex, Gemini CLI, Copilot, v0, Lovable, Bolt and similar AI build tools.
Includes a blog, Launch Kit, affiliates program, design requests and a public GitHub repository.
Duply addresses a common failure mode in AI-assisted development: the model invents a visual style from a vague prompt, and the resulting interface feels random and unfinished. Instead of hoping for a good outcome, you pick a design reference from the Duply library and copy a single DESIGN.md file into your project. That file documents typography, spacing, color, components, layout patterns, interaction rhythm and overall visual direction in language an agent can follow.
The company describes its work as independent analysis of publicly observable design patterns, with documented substitutes for licensed typefaces and no redistribution of proprietary assets. A disclaimer on the site notes that trademarks belong to their respective owners and that Duply offers no affiliation with or endorsement from the sites it analyzes.
The library is aimed at founders, developers, designers and AI builders who want faster UI direction and fewer rounds of prompt tweaking. Supporting resources include a blog, a Launch Kit, an affiliates program, a request-a-design flow, and a public DESIGN.md repository on GitHub. The tool works with popular coding agents such as Claude Code, Cursor, Codex, Gemini CLI, Copilot, v0, Lovable and Bolt.
Give your coding agent a concrete design reference so the first build looks intentional instead of improvised.
Use one DESIGN.md as a shared reference so generated components stay consistent across screens and features.
Document the qualities you care about so an agent reproduces them instead of guessing from a short prompt.
