How It Works
Simply select a drawing tool from the left panel and start drawing on the canvas. Use boxes for containers, lines and arrows for connections, and text for labels. The ASCII preview updates in real-time.
When finished, copy the ASCII art directly to your clipboard or download it as a text file. The output uses standard Unicode box-drawing characters that work in most terminals and text editors.
