Build Mermaid diagrams in Raltey
Raltey can draft Mermaid-compatible diagrams on a visual canvas. Useful when your docs already render Mermaid (GitHub READMEs, Notion blocks).
What you can do
Built for Mermaid diagrams that ship.
- Flowchart, sequence, ERD, state, class, Gantt, journey on the same canvas.
- Export the diagram as an image; matching Mermaid syntax in supported types.
Try these prompts
Type, paste, done.
1.Mermaid flowchart for a CI/CD pipeline with linting, tests, and deploy.
2.Sequence diagram for an OAuth2 flow.
