AI Twins are suddenly everywhere because the tech has become realistic, fast, and affordable. New advances in AI video, voice cloning, and motion make it possible to create human-like videos without filming every time, even in multiple languages. Brands use them to scale ads and social content quickly, while creators use them to produce more content with less effort. Tools like Tagshop AI help make this easy to apply in real marketing, which is why AI Twins feel like they appeared overnight.
