Graphical supplies theme files and component context for coding agents

Graphical helps you define an interface's visual language before asking a coding agent to build or revise screens. Its theme builder lets you adjust colors, typography and spacing, then export resources the agent can use in a project.

The intended benefit is a shared reference for design decisions. A prompt asking for a cleaner screen leaves many choices open; theme files specify the values and patterns the implementation should follow. Graphical provides that material, while your coding agent performs the code changes.

Set values for the interface as a whole

The editor covers brand, neutral and status colors, with separate values for light and dark mode in one theme. Typography controls include font families, weights, sizes and line heights. Spacing uses a shared scale for padding, gaps and component sizes.

You can also choose icons and customize corner radii, strokes and shadows. Motion controls cover springs, easing and timing for interactions. Defining these together gives you a reference for checking a button, menu or data table against the rest of the interface.

Graphical offers five customizable starting styles, or you can begin with your own colors and other design values. Review text contrast and spacing in actual screens as well as the theme preview; a set of tokens does not establish that all resulting layouts will be readable.

Give the coding agent installable context

Downloads include theme tokens and React component source. They also contain GUI.md, detailed light and dark references, setup instructions and three coding-agent skills. The documented workflow is to share these resources and the setup prompt with your agent, then describe the screen or change you want.

The included components use Base UI. You can install the theme with shadcn or download it directly. The publisher says the theme files can guide other component libraries, frameworks and languages, though those implementations still need to map the design values to their own components.

Distinguish native guidance from the visual editor

Graphical says you can give the theme files to an agent working on native iOS or Android components. Its visual component editor currently supports web components only. That distinction matters if your main goal is editing a native control in a preview rather than supplying a design reference for code generation.

The page describes a one-time purchase for the theme builder, launch styles and foundation components, with unlimited projects and ongoing builder updates. It lists $49 at capture, alongside a previous $99 price; confirm the checkout terms before buying.

Use a small existing screen as a first application. Inspect whether the agent used the theme values, preserved behavior and handled both color modes before applying the same instructions across a larger app.
