What Archflow is
Archflow is a web platform for designing software systems with AI. Its built-in assistant turns natural-language input into architecture diagrams, user stories, scope cards, and technical documentation. The diagram editor supports UML classes, interfaces, components, databases, and services, with drag-and-drop creation plus undo and redo history. Teams can work together using live cursors, presence indicators, synchronized editing, comments, and activity feeds. Kanban boards track story status, estimates, and acceptance criteria, and connect stories directly to architecture diagrams. Documentation uses a Markdown editor with live preview and categories, and can also be generated with AI. The Free plan is free, billed at $0/forever, and includes one project, three diagrams per project, Kanban user stories, a basic UML editor, and email support. Pro is $5 a month, billed at $5/per month, with unlimited projects and diagrams, AI-generated stories, scope and docs, real-time collaboration, and priority support. Archflow runs on the web and offers a free trial.
