In their own words
Archflow
Archflow is a web platform for collaboratively designing software systems with AI. Its assistant can create architecture diagrams, user stories, scope cards, and technical documentation from natural-language input. The visual editor supports UML classes, interfaces, components, databases, and services, with drag-and-drop creation and undo/redo. Teams can edit together using synchronized changes, live cursors, presence indicators, comments, and activity feeds. Kanban boards track user-story status, estimates, and acceptance criteria, and link stories to architecture diagrams. Documentation is created in a Markdown editor with live preview and categories, and can also be AI-generated. The Free plan costs nothing and allows one project and three diagrams per project. Pro costs $5 a month and includes unlimited projects and diagrams, AI-generated content, real-time collaboration, and priority support. Archflow says prompts and selected project context are sent to OpenAI's API, and AI chat history is stored on its servers.
