Ways to create

• AI — describe the diagram; AI writes it. ✨ Fix repairs syntax errors, 💡 Explain describes it, ⇄ Convert turns a flowchart into a sequence diagram, mind map and more.
• Visual builder — add shapes (box, decision, database, circle…) and connections from a form; the code updates for you. Mind maps use an indented outline.
• Text — Mermaid, Graphviz DOT, PlantUML, D2 and more, with a code editor, live preview, zoom and pan.
• 25 templates — flowchart, mind map, sequence, class, ER, state, Gantt, timeline, journey, pie, quadrant, Git, XY chart, Sankey, architecture, Graphviz, Vega-Lite, PlantUML, D2, WaveDrom, nomnoml, ABC music and GeoJSON maps.
