What flow-chart.io is
flow-chart.io turns plain-language descriptions, documents, or repository context into editable diagrams for software engineers, architects, and IT professionals. Its diagrams are scene graphs with editable nodes, connectors, labels, and lanes, rather than static images. The product covers 17 diagram domains, including BPMN-inspired processes, C4, UML, cloud architecture, ERDs, threat models, DevOps pipelines, networks, and org charts. Users can refine diagrams through chat and browse, compare, or restore earlier versions. A GitHub connection can scan a codebase to ground a diagram in the system it describes. Diagrams export to SVG, PNG, PDF, JSON, and Mermaid. Image-to-diagram conversion attempts to reconstruct supported raster images as editable objects, but results vary with image quality and complexity and require review. The free plan costs nothing and includes up to 3 saved projects and credits described as about five standard diagrams, with no credit card required. Pro costs $19 a month. A REST API and MCP server are also listed.
