Stitch 3.0 by Google

Google just dropped Stitch 3.0, and it's exactly what designers have been quietly begging for — an AI that generates and iterates UI screens live on a canvas, not in some static mockup void where nothing talks to anything else. Josh Woodward (yes, the same Googler who's been building their design tools for years) helmed this one, and the fact that it's hit 3.0 tells me this isn't some pilot or press tour play — it's shipped, battle-tested, and ready. Most AI UI tools spit out pretty pictures and call it a day; Stitch actually lets you build and revise in motion. That's the vibe shift everyone's been waiting for.
