About ArchGen

Generate architecture and system overview diagrams from natural language with multiple styles and a focus on clarity.

What is ArchGen

A straight-to-diagram generator

Describe your system and ArchGen generates clear, layered architecture diagrams or system overviews - no manual drawing or complex editors.

Core focus

Clarity, speed, consistency

We prioritize readability and communication over endless drawing controls.

  • Clear, layered architecture diagrams
  • At-a-glance system overviews

  • Useful beyond engineering: business, workflow, and landscape diagrams
What it is not

Not a heavy drawing editor
