ChartDB

What is ChartDB AI

ChartDB AI is a free, open-source database diagram editor that turns SQL into clear, editable ER diagrams and generates AI-assisted DDL scripts. With a single query, you can visualize tables, keys, and relationships, then refine your schema with an intuitive canvas. The tool simplifies schema design, documentation, and migration by exporting clean DDL in your preferred SQL dialect. Whether you’re prototyping a new model or aligning legacy databases, ChartDB AI streamlines schema visualization, ERD creation, and SQL-driven design without vendor lock-in.
