AI Diagram Maker

AI Diagram Maker is a conversational diagramming tool for developers and teams. Users describe a system, process, or flow in plain English, and the AI generates a diagram that can be edited in code view or refined by chatting with the AI. The page says the AI produces D2 diagram-as-code, applies automatic layout and styling, and supports exports as PNG, SVG, or diagram code. It also describes an MCP server for generating diagrams inside IDEs such as Cursor, Claude Desktop, and VS Code, and a Code to Diagram feature for GitHub repositories that is marked as coming soon. The page lists free tools including an AI Flowchart Generator, AI Sequence Diagram Generator, AI ERD Diagram Generator, and AI UML Diagram Generator. Pricing mentions Plus and Max plans for revision history, but no prices are stated.
