Maia for Domain Model helps you generate new domain models and explain and improve existing domain models. It has some limitations. For more information, see the Limitations section below.

Using Maia for Domain Model

Describe your application or its main goals in the chat. Maia uses this information to generate a relevant domain model for you. In Studio Pro 11.1 and above, you can also attach up to one image and one PDF to help Maia better understand your request. For more information, see the Attachment Requirements section below.

After Maia generates a domain model, if the dedicated chat is still active, you can continue asking Maia to add entities and associations to the domain model. Maia also supports adding more attributes to an existing entity in the domain model. You can also ask Maia to explain or improve the generated domain model.
