Google's Carbon self-checks code and screen output during builds

Google says its Carbon tool checks both its code and the on-screen result while it builds projects, from complete apps to 3D worlds, and fixes errors as it goes.

When data is missing or flawed, Carbon flags the problem for the user rather than guessing, according to Google's post on X.

A separate Google for Developers post says Carbon can generate custom, animated UI micro-interactions for existing apps while keeping typography, motion, and state consistent. The post says that given one shared design style and a single prompt per widget, Carbon coded each interactive UI component it shows.
