Google Updates Stitch AI Tool with Canvas and Agent

Google unveiled an updated version of its experimental AI design tool, Stitch, on Thursday, introducing an AI-native canvas and a reasoning agent to transform natural language descriptions into interactive user interfaces. The platform, available through Google Labs, aims to streamline the design process for developers and non-designers alike by interpreting prompts that convey intent, tone, and overall feel, which Google terms "vibe design."

Stitch, originally a tool for generating UI layouts from text prompts, now features an infinite canvas where users can input images, text, or code to provide context. A new design agent tracks project history, reasons through iterations, and explores multiple concepts simultaneously without losing progress. Users describe app ideas or business concepts, and the system produces high-fidelity mockups, connects screens into prototypes, and maps user flows automatically. For instance, a prompt about a mobile banking app could yield editable layouts with consistent navigation and visual elements.

Key enhancements include voice control, enabling real-time changes by speaking directly to the canvas, such as requesting critiques or variations in...
