AI Diagram Maker review
A strong fit for developers turning code, documents, and prompts into editable diagrams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AI Diagram Maker is a web-based tool for developers and technical teams that need to visualize software architecture, workflows, and codebases. It turns natural-language descriptions, images, documents, notes, and GitHub repositories into editable diagrams, including architecture diagrams, flowcharts, sequence diagrams, ERDs, and UML diagrams. Automatic layout and styling, conversational refinement, direct D2 code editing, and exports to PNG, SVG, and diagram code support both technical drafting and further editing.
Pricing is straightforward across three monthly plans. Basic costs $0 per month and includes AI diagram generation and editing, diagram creation from documents, GitHub repository code-to-diagram generation, and exports to diagram code, SVG, or PNG. Plus costs $10 per month and adds 30 days of diagram revision history and priority support. Max costs $20 per month and includes the Basic features, 90 days of revision history, and priority support. Developers who only need generation and export can start with Basic; teams that need longer history should consider Max.
Its strongest fit is a developer workflow built around code and technical tools. GitHub repository conversion is paired with integrations for Cursor, Claude Desktop, VS Code, and MCP clients, while MCP Server access extends the product into developer tools. The breadth of supported inputs and diagram types makes it useful beyond a single diagram format, but the focus remains technical rather than general visual design. Developers seeking code-centered diagramming should find the feature set well aligned; teams requiring a native desktop or mobile application should look elsewhere.

- Revision history and priority support require a paid plan
- Plus and Max differ mainly by revision-history duration
