HeyGen

HeyGen (pôvodne známa ako Surreal Ads) je priekopnícka platforma pre AI-poháňané generovanie videí, ktorá demokratizuje tvorbu profesionálneho video obsahu. Spoločnosť HeyGen Inc. vytvorila riešenie, kde stačí textový scenár na vytvorenie realistického videa s AI avatarmi, čím eliminuje potrebu profesionálnych hercov, drahého štúdiového vybavenia a zložitého postprodukčného procesu.
