🚀 引言 / Introduction

各位還在為了跟 AI 溝通『請把左邊那個東西移一點』而跟對話框搏鬥的人，這款工具就是救星。想像一下，你不用在對話紀錄裡沒完沒了地捲動，而是在一個像 Miro 或 Figma 的無限白板上，直接把想法變圖。這不是那種要你肝掉三天三夜才能跑起來的複雜系統，而是讓你在下午茶雞排還沒冷掉前就能部署好的高效能畫布。 | For those tired of fighting with chat boxes just to say 'move that thing on the left a bit,' this tool is your savior. Imagine an infinite canvas like Miro or Figma where ideas turn into images instantly, without endless scrolling through chat histories. It's not a complex system that requires three sleepless nights to set up, but an efficient canvas you can deploy before your afternoon fried chicken cools down.
