VSDX.ai is an AI-powered tool that converts spreadsheets, PDFs, Word documents, images, and audio recordings into structured, editable Visio diagrams. It supports nine diagram types including flowcharts, swimlanes, architecture diagrams, BPMN, UML, and ER diagrams. Users can edit results in an embedded draw.io canvas, manage version history, and export native .vsdx files compatible with Microsoft Visio. The platform keeps uploaded source files private within each project and also supports importing existing VSDX files for further editing.
