StackHuddle turns quick thinking and clear speaking into a game. You get a topic, a 2-minute research sprint with an AI assistant, then you present out loud — concisely, from memory — while your mic transcribes you. An AI judge scores accuracy, depth, clarity, and coverage with specific feedback, so every round makes you a sharper speaker. Play head-to-head with up to 5 friends, or solo with a score history to track your progress. Browser-based, no installs; guests join with just a link.
