AI Diagram Generator

Effortlessly create flowcharts, ERDs, mindmaps, sequence diagrams, class diagrams, state diagrams, and Gantt charts from plain English descriptions. This web-based application is designed for ease of use, requiring no signup and offering free generation, editing, and export capabilities. The AI automatically detects the appropriate diagram type from your natural language input, or you can manually select it. Diagrams are rendered instantly, and you can further refine the generated Mermaid or markmap source code in a split view. Export your creations as SVG for scalable vector graphics, PNG for easy sharing, or Markdown/OPML for mindmaps compatible with tools like XMind and Obsidian. The service supports both English and Chinese input, ensuring accessibility for a wider range of users. While free to use, a daily rate limit is in place to manage API costs, which resets every 24 hours.
