What is ERBuilder?
ERBuilder is a tool for creating entity-relationship diagrams (ERDs) using generative AI. Instead of manually drawing database schemas from scratch, you describe what you need and the tool generates a diagram, which you can then edit and refine in real-time. It's designed for database architects, developers, and business analysts who need to visualise data structures quickly without spending time on manual diagram layout. The tool offers customisation options so you can adjust the generated output to match your specific requirements, making it useful for both initial exploration and detailed documentation.
