Generating and Editing Your Site
When you submit a prompt, Build creates a new project and shows a step by step checklist as it works, typically covering choosing a visual direction, building the core experience, adding responsive polish, and running a final quality check. The agent narrates its plan as it goes, and a live preview appears on the right, updating as the build progresses.
You can play exciting game while Computer is Building your amazing App.
Once your site is ready, the agent will summarise what it built and invite you to refine it further.
To make changes, use the Ask Computer box below the conversation to describe what you want adjusted, for example changing a section, updating the colour palette, or adjusting layout. The agent edits your existing project rather than starting over.
Other things you can do from the editor:
Switch to Plan mode if you want to discuss a change before it is made.
Open the Code view to browse every file in your project.
Use the history icon to review or restore an earlier version.
Use the route bar and device toggle in the preview to check different pages and screen sizes.
Rename your project from the project settings or the project menu.
