Modify an existing application

Modify starts from an existing Ready application version and applies a new user request.

Use Modify when you want to change an application that already exists.

Example:

> Add a wishlist page for saved products.

What happens

DeplAI edits from the finished version. Only the affected parts of the application are updated, then the preview is checked again. A new saved version is created. The previous Ready version remains in history.

Modify is available when the conversation is not currently building, and when a finished build has stored source. If the latest build failed, Fix or Retry first.

In the composer, choose Modify, describe the change, and send. You can attach files or checks as context.
