FAQ

What are the primary features available for professional diagramming and sketching within the DGM platform?

DGM provides a suite of professional tools including smart shapes with scripts, hand-drawn styles, and specialized libraries for UML, ERD, and UI wireframes. Users can export their work as PNG or SVG files and utilize a seven-day version history to restore previous iterations of their diagrams (verified: 2026-01-30).

How does the AI assistant function to help developers during the diagramming process?

The platform includes an experimental AI assistant that utilizes OpenAI's GPT-4 Vision technology. This feature allows users to generate code directly from their diagrams, bridging the gap between visual planning and software implementation (verified: 2026-01-30).

Is there a cost associated with using DGM for personal or local diagramming projects?

DGM is free forever for users who work with local files on their own devices. However, advanced features such as cloud storage, real-time team collaboration, and web publication are separate from the basic local-use model (verified: 2026-01-30).
