Rainbrand is a brand infrastructure platform that builds and maintains shared brand context for AI agents and products. It ingests brand guides, logos, fonts, website content, and Figma assets into a single centralized system. Agents and products can access this context via an MCP server or REST API, enabling them to request task-specific briefs, generate on-brand content, and review outputs before they ship. Rainbrand integrates with tools such as ChatGPT, Claude, Claude Code, and Cursor without requiring changes to existing workflows.
