What is ChatDiagram?
ChatDiagram is an AI-powered diagramming platform that converts natural-language descriptions into structured visual diagrams. Its routing system selects among specialized Mermaid, Markmap, and Schematex engines based on the requested diagram type. The platform supports common visuals such as flowcharts, mind maps, timelines, ER diagrams, sequence diagrams, architecture diagrams, and specialized engineering diagrams. It is designed for developers, engineers, analysts, educators, product teams, and other knowledge workers who need diagrams for documentation, planning, communication, or analysis. Users can save generated artifacts and export diagrams for use in presentations, technical documentation, and collaborative workflows.
