VibeSchema is a free, AI-first ER diagram generator. You can describe your database model in text and see the generated database model instantly as an ER diagram!
Once you have generated the ER diagram from text, you can refine your entity relationship diagram by chatting. For example, if you don’t like some design choices, you can just mention what you would change and instantly see the updated ER diagram. This way you can reorganize your whole database diagram in seconds!

Why use an AI ER diagram generator
Restructure your entire database in one sentence. Traditional ER diagram tools make you manually delete tables, redraw connections, and edit code for each little tweak. With VibeSchema, just say ‘split the users table into customers and admins’ and the diagram updates instantly.
Building a booking system but not sure what tables you need? Describe your app and let VibeSchema propose a starting schema. You’ll have a complete ER diagram to react to instead of staring at a blank canvas.
Perfect for live discussions with your team. Debating whether to normalize a table or change a relationship? Make the change mid-conversation and see the result immediately. No more pausing the meeting to manually redraw the diagram.
No learning curve to slow you down. Other ER diagram tools require you to learn a drag-and-drop interface or memorize schema syntax before you can start. VibeSchema works the way you already think: describe what you need in plain English and the diagram appears.
Frequently asked questions
Do I need to know SQL or DBML? No. You describe your data model in plain English and VibeSchema handles the rest. If you want to edit the underlying code directly you can, but it’s never required.
Can I export the ER diagram to PostgreSQL? Yes. Once your diagram is ready, use Export > PostgreSQL to get a complete SQL schema ready to run. Learn more about the AI PostgreSQL generator.
What is an ER diagram? An entity relationship diagram is a visual map of your database: tables as boxes, relationships as lines between them. It’s the standard way to design and communicate a data model before writing code.
