ER Diagram AI

ER Diagram AI uses artificial intelligence to make database design fast and approachable. Convert a rough outline into a complete ER diagram, edit visually or via Mermaid text notation, and export ready-to-run SQL for MySQL, PostgreSQL, Oracle, and SQLite. The extension runs smoothly with intuitive controls, a dark theme, and no account required.

Built for developers, teams, and learners, ER Diagram AI supports Google Drive for multi-device editing, import/export for sharing and collaboration, and quick prototyping or client presentations. Use it to review existing schemas, onboard engineers, or rapidly design databases for new apps — all with automatic SQL conversion and flexible editing options.
