Paper

Paper (paper.design) is a modern, agent-native design tool built on HTML and CSS web standards — a connected canvas where teams design, share, and ship with AI agents. Instead of drawing abstract vector representations of interfaces, Paper renders real HTML/CSS, so what you design is production code (exportable as React/Tailwind JSX) and what you code appears on the canvas. AI agents connect through a first-party, authenticated Model Context Protocol (MCP) server to read and write design files directly (Cursor, Claude Code, Copilot, Codex), and the app ships a browser-side WebMCP origin trial. Paper also publishes the open-source Paper Shaders component libraries. Backed by Accel, Bullpen Capital, IVP, Sapphire Ventures, and SoftBank Vision Fund.

Paper is profiled on the APIs.io network. Tagged areas include Company, Design, Design Tools, MCP, and Agents.

Paper’s developer surface includes documentation, API reference, changelog, engineering blog, support, pricing, signup flow, and 13 more developer resources.
