# Diagramming AI

> Diagramming AI is an AI-powered diagram generator that turns natural-language prompts into editable Mermaid, PlantUML, GraphViz, and Excalidraw diagrams. Describe what you want in plain English and get a flowchart, sequence diagram, ER diagram, class diagram, gantt chart, mindmap, and more — then refine it conversationally and export it.
