Open .drawio output vs. proprietary diagramming
Eraser's DiagramGPT generates diagrams from text, but in a proprietary format. Diagrams.so generates native .drawio files that work everywhere.
Overview
Eraser is a documentation-first tool with DiagramGPT, an AI feature that generates diagrams from text descriptions. The output is clean and professional, but locked into Eraser's proprietary format. There is no .drawio or standard format export.
Why teams choose Diagrams.so
- Native .drawio export—edit in Draw.io desktop, Confluence, VS Code, not just Eraser
- Architecture warnings engine—Eraser generates but doesn't validate
- Community gallery with fork/remix for collaborative learning
- Opinionated Mode suggests missing components with rationale
- Credits-based pricing that accounts for diagram complexity
- Import existing .drawio files for free on all plans
