Database Schema & ER Diagram Engine

AI-Powered ER Diagram Generator for Database Schema Design

Designing a relational database without a clear ER diagram is asking for architectural debt. Paperxify's AI ER Diagram Generator reads your data model description and generates a complete entity-relationship diagram in seconds.

PK / FK Notation

Primary keys and foreign keys are automatically identified and annotated with PK/FK labels in the diagram.

Cardinality Relationships

One-to-one, one-to-many, and many-to-many relationships rendered with correct crow's foot or UML notation.

Highly Rated
"Generated our entire database ER diagram from a written spec in under 30 seconds. PKs, FKs, and cardinality were all correctly mapped."
