Beauty Diagram

Beauty Diagram is a diagram editor and beautifier that takes code-based diagrams written in Mermaid, PlantUML, or draw.io and automatically improves their appearance, re-laying out flowcharts with orthogonal routing, applying modern styling, and exporting to SVG or PNG. It supports 15 diagram types across three formats, letting users paste source, preview it live, and clean up the layout in one click, with nine customizable themes and in-canvas color customization without touching the source code. Beauty Diagram also offers AI-powered diagram generation and refinement from text descriptions, embeddable SVG exports for GitHub and Notion, five animated SVG styles, and integrations including a Chrome extension, Obsidian, VS Code, CLI, and API. Pricing includes a free tier for basic usage, subscription tiers (Early Bird, Standard, Premium) ranging roughly $20-$600/year, and a pay-as-you-go credit system starting at $2.99 for one-time exports.
