AI Diagram Maker

Description

AI Diagram Maker is an AI-powered tool that creates professional software architecture, UML, and flow diagrams from natural language instead of manual drag-and-drop. You describe your idea in plain English, and an AI agent analyzes the requirements, identifies components and relationships, and generates clean D2 diagram-as-code that renders as a visual diagram.

It supports many diagram types, including system architecture, microservices, database schemas, network diagrams, flowcharts, and sequence diagrams. You can iterate conversationally, asking the AI to change a diagram in natural language, or switch to code view to edit the underlying D2 directly. It also creates diagrams from uploaded images, documents, and notes, and can analyze public or private GitHub repositories to visualize a codebase's architecture automatically.

The tool uses D2 for its simple, AI-friendly syntax, automatic layout engine, and integrations with tools like Confluence and Obsidian, so you can focus on the architecture rather than tool mechanics. An MCP server lets you generate diagrams inside Cursor, Claude Desktop, VS Code, or any MCP client, turning natural language, code, ASCII, images, or Mermaid into editable diagrams.

Diagrams export as PNG, SVG, or D2 code, and higher tiers add revision history. Pricing is credit-based and usage-metered, with a free Basic plan and paid Plus and Max tiers that add more monthly credits, longer revision history, and priority support.

How to use AI Diagram Maker?

1. 1

   Describe your diagram: Type your architecture or process in plain English.

2. 2

   Generate: The AI produces D2 code that renders as a professional diagram.

3. 3

   Refine: Ask the AI for changes in natural language or edit the D2 code directly in code view.

4. 4

   Import a source: Optionally upload a document or provide a GitHub repository URL to generate from.

5. 5

FAQ from AI Diagram Maker

• How does AI generate diagrams from text?

  The AI agent uses language models to understand your natural language description, identify components and relationships, and generate clean D2 code that represents your architecture visually.

• What is D2 and why do you use it?

  D2 is a modern diagram-as-code language with simple syntax that is easy for AI to generate, powerful automatic layout engines, flexible styling, and integrations with tools like Confluence and Obsidian.

• Can I edit the generated diagrams?

  Yes. You can switch to code view to edit the D2 code directly, or chat with the AI to request changes in natural language, and it modifies the diagram based on your feedback.

• What types of diagrams can I create?

  You can create system architecture, microservices, database schemas, network diagrams, flowcharts, sequence diagrams, and more, since the AI understands various architectural patterns.

• Can I generate diagrams from my code repository?

  Yes. The Code to Diagram feature analyzes public and private GitHub repositories from a URL and automatically generates architecture diagrams of the codebase.

• How does pricing work?

  Pricing is credit-based and usage-metered, with credits resetting monthly. A free Basic plan includes generation, editing, and export, while Plus and Max add more credits, longer revision history, and priority support.
