Paper is a collaborative design platform that connects design, development, and AI-driven workflows within a single digital canvas. Built on open web standards, the platform enables teams to create visual designs that translate directly into functional HTML and CSS code. This approach reduces the friction between designers and developers by ensuring that visual work and production code stay synchronized. Paper integrates with development environments, APIs, and AI agents so that components, styles, and design tokens can be automatically updated across the design canvas and the codebase. Teams can bring real data, content, and application context into the design environment, allowing them to build interfaces using actual information rather than placeholder content. The platform supports collaboration between humans and AI agents that can assist with tasks such as layout adjustments, responsive variants, and repetitive design work. Paper Desktop expands this capability by connecting the canvas to apps, repositories, and development tools used throughout the workflow. Designers and developers can iterate quickly while maintaining a continuous loop between design and production code. This unified system helps reduce translation errors and keeps projects aligned across teams. By merging design, code, and AI assistance into one environment, Paper enables a more fluid product development workflow.
