According to The Rundown AI on Twitter, Google updated its Stitch UI creation tool with a new "vibe design" experience that adds voice control for speaking to the design canvas and receiving real-time critiques, plus instant prototyping that converts static screens into interactive flows (source: The Rundown AI). As reported by The Rundown AI, these AI-driven features aim to accelerate UX iteration by enabling conversational design feedback and rapid usability testing directly in Stitch, reducing handoffs and shortening design-to-dev cycles for product teams (source: The Rundown AI). According to The Rundown AI, the update positions Stitch to compete with AI-enhanced design platforms by embedding multimodal interaction and automated prototyping into the core workflow, creating opportunities for faster A/B exploration and lower cost of UI experimentation for startups and enterprises (source: The Rundown AI).
