Schema diagrams
Generate interactive entity-relationship diagrams from any connected source, with foreign keys and inferred joins detected automatically.
AI-Powered Schema Visualization
The ERD Designer generates interactive entity-relationship diagrams from your connected data sources using Mermaid.js.
How to Use
- Connect a data source — the ERD designer works with any connected database or uploaded file.
- Ask for a diagram — use natural language: "show the ERD for this database", "visualize the schema", or "how are these tables related?"
- Interactive output — the diagram renders inline in the chat with table names, column types, and relationship lines.
Features
- Auto-discovery — foreign keys and implicit relationships are detected automatically.
- Focused views — ask for specific subsets: "show only the tables related to billing".
- Export — copy the Mermaid source or download as SVG/PNG.
