A diagram editor with AI assistance, live preview, and export tools.
Write diagram syntax in the editor pane. The diagram updates live in the preview. Use File > Templates to start from a preset.
Scroll to zoom, drag to pan. Use the zoom controls or press Z to toggle between zoom and pan modes. Press Fit to auto-fit the diagram.
Click the link icon in the editor header (next to the line count) or press I to toggle Inspect Mode. When active, clicking a node in the preview jumps to its source line in the editor. Moving your cursor to a line in the editor centers and highlights the corresponding element in the preview.
Open with AI Chat or Cmd /. Ask the AI to analyze, improve, or generate diagrams. Use Load Repo to give the AI context from a codebase. Requires a Claude API key (set in Settings).
Enable Note Mode from the View menu (or press N). Click anywhere on the preview to add sticky notes. Drag to reposition, click to edit.
Export diagrams as PNG, SVG, or PDF — with or without notes. Choose export scale (2x-8x) for higher resolution. Use Cmd Shift C to copy as image.
Save multiple diagrams as projects. Each project stores its diagram, chat history, notes, and repos. Use Share to generate a shareable URL.
