Paper Builder: Slack Brainstorms to Live Products in One Thread

Paper Builder is an AI agent that designs and deploys a product based on teammates' Slack messages, showing the results right inside the channel. With Paper Builder you can design, refine, and deploy without leaving the Slack thread. From a single screen to entire flows. It is a multi-agent orchestrator, using a Python server and Claude CLI to create designs in Paper through its MCP, and generate a navigable live demo on Vercel.

"Mention the bot, describe the feature, and see it live."

The system operates in two primary modes:

• Design Requests: The agent connects to Paper, creates or edits high-fidelity artboards on the canvas, and posts screenshots back to the Slack thread for instant feedback.
• Implement Requests: The agent exports the design as React JSX, wires up the navigation, scaffolds a Vite project locally, and deploys it to Vercel. Within seconds, the team gets a live, navigable URL.
