Overview
The AI Diagram Maker is an intelligent tool designed to help users generate various types of diagrams such as software architecture, flowcharts, UML diagrams, and ERD (Entity-Relationship Diagram) diagrams.
Users can generate these diagrams by simply typing their ideas in plain English, eliminating the need for complex interfaces, toolbars, menus, and manual placement of elements.
This AI-powered tool can also transform existing notes, documents, or whiteboard sketches into structured diagrams. It offers automatic layout and styling, allowing for professional results instantly.
Diagrams can be exported in multiple formats such as PNG, SVG, or as Diagram code, making them ideal for documents, presentations, or repositories. The tool also offers a conversational interface for refining and editing the diagrams, and users can switch to code view for direct edits.
Other features include diagram revision history tracking and upload of attachments, which the AI complements by transforming them into diagrams. This tool is potentially beneficial to developers due to its fast processing time, intuitive interface, and the freedom it offers to users by allowing them to focus on architecture as opposed to tool learning curves.

Releases 3
New: Plan Mode for complex diagrams
AI Diagram Maker now supports a planning-first workflow for complex diagrams.
Create a plan before generating the diagram
Review and edit the structure, components, and flows first
Generate the diagram only when the plan looks right
Reduce repeated back-and-forth edits
Lower overall AI credit usage for more complex diagraming tasks
This is especially useful for architecture diagrams, workflows, and other diagrams where structure matters before visual generation.
New: MCP server support
AI Diagram Maker now supports MCP, so users can create diagrams directly from MCP-compatible agents and editors.
Supported workflows include:
Cursor
Claude Code
VS Code
Any other MCP-compatible agent
This makes it easier to generate diagrams without leaving the tools users already work in, reducing context switching and repeated prompting across apps.
Flexible Export Options – Download diagrams as PNG, SVG, PDF, or MermaidJS format for broader compatibility.
Publish & Share – Generate a hosted diagram with a shareable URL for easy collaboration and distribution.
We’re excited to introduce a major upgrade to AIDiagramMaker—designed to give you more control, faster iteration, and lower cost, while keeping AI where it adds the most value.

Didn't really do the graphs that i thought it would do. Good for simple graphs, like for a presentation
