No drag-and-drop, no syntax to learn — write what the system is and the AI draws it with proper layout, icons, and labeled connections
No sign-up required • Free to try
Turn short text prompts into editable architecture, cloud, and data diagrams in seconds
Your repo already knows the architecture — let an AI agent read it and draw the diagram, instead of reconstructing it by hand
Model data platforms with ingestion, storage, transformations, and analytics in minutes
Common questions about text to diagram, in one step
Those turn a syntax you must learn into a rendered chart. Here the input is ordinary prose — the AI decides the components, connections, layout, and icons. You get an editable canvas rather than a static render, so the 20% the AI got wrong takes seconds to fix instead of a syntax hunt.
System and data architectures: services, databases, pipelines, cloud components, and the flows between them. It is not a flowchart or slide tool — the payoff is highest where real infrastructure with real names needs to be drawn accurately.
Yes — follow-up instructions like "group the AWS parts", "add a cache between API and DB", or "label the async edges" edit the existing diagram rather than starting over. Iterating in text is the entire workflow.
Yes — Datadef ships an MCP server, so Claude, Cursor, or any MCP client can generate and edit diagrams from a conversation or straight from your codebase, and export PNGs back into the chat.
