Generate diagrams from text or an image, revise an existing diagram with natural-language instructions, list and read saved diagrams, inspect task and version history, and export editable draw.io XML or JSON. Saved diagrams open in the FlowchartAI web editor for further editing and PNG/SVG rendering. The hosted Streamable HTTP endpoint supports OAuth with PKCE and scoped API keys.
