diagram-design: Brand-matched diagrams in 60 seconds from just a URL

When you request a diagram from an AI coding agent, you typically get a list of generic boxes with rounded corners. This tool solves that by providing 38 Editorial diagram types. It applies a restrained visual language with no shadows or unnecessary decorations, using accent colors only on the one or two elements that readers should see first.

It supports various types including architecture, flowcharts, sequence diagrams, state machines, ER diagrams, timelines, Sankey diagrams, and wordly maps. Each diagram is provided in three static variants: minimal light/dark modes and a full editorial version, output as self-contained HTML and SVG files that can be opened directly in a browser. They are ready to use immediately without build steps or external image dependencies.

There is no need to spend 30 minutes picking colors in Figma or manually aligning elements. Simply provide a website URL, and the agent extracts the site's palette and font stack, mapping them to semantic roles in the diagram such as paper, ink, accent, and link colors. This process allows you to generate diagrams that match your brand identity within 60 seconds.

It works as a plugin in major AI development tools such as Claude Code, Codex, Factory Droid, and Pi. It also supports re-graphing existing Mermaid or draw.io sources into the specified format and level of detail. It is suitable for developers and technical writers who need to produce visual assets quickly while maintaining design quality when documenting complex system structures or processes.
