Graphical is a theme builder for designers, developers, and anyone building an app with a coding agent such as ChatGPT, Claude, or Cursor. It lets users create visual design languages by customizing colors, typography, spacing, icons, and component states, then export the results as shadcn-compatible theme tokens and React components built on Base UI. Each download includes a GUI.md file, detailed light and dark mode theme references, setup instructions, and three coding-agent skills to help the agent apply and extend the theme. Graphical is sold as a one-time purchase granting unlimited project use with ongoing theme builder updates.
