AI ER Diagram Generator

How It Works

This is a free AI ER Diagram Generator tool for quickly making database ER Diagrams from text. Simply describe in a prompt what your diagram should look like, in text or by pasting a code snippet, upon which the AI will generate your ERD. From there you can iterate until you get the desired result.

When finished, you can press the button in the bottom right of the canvas to export your ER diagram as a PNG or SVG image. You can also continue working on your diagram in VibeSchema, if you're looking for a complete database schema tool.

Note that this tool is for relational ("crow foot") database ER diagrams. In particular, it is not appropriate for Chen-notation ERDs.

What Is an ER Diagram?

An entity-relationship (ER) diagram is a visual map of a database: each box is a table (an entity), each row is a column, and the lines between boxes show how the tables relate — which records point to which. It is the fastest way to understand or communicate the shape of a data model, whether you are planning a new app, documenting an existing database, or reviewing a design with your team.

Want to Edit the Schema Directly?

This page is built for speed: describe, see, export. If you want to edit the underlying DBML by hand, organize tables into views and groups, or fine-tune which column indicators show, open the menu and choose Open in full editor to continue in the full VibeSchema schema tool.

Just Need an Image From DBML?

If you already have a schema written in DBML and only want a picture, the DBML to PNG and DBML to SVG tools convert it to a downloadable diagram in one step.
