All four names—Kayi Cloud (keyiyun.cn), Keyiyun Group (zcbjr.cn), Baifukeji Group (baifukeji.cn), and Chuangwuzhe Artificial Intelligence (cwzai.com)—refer to the same overarching Chinese AI business services company, which operates under multiple brand and domain names. The core entity is Keyiyun Group, which owns the Chuangwuzhe Human Industrial Intelligence Research Institute. "Kayi Cloud" appears to be an English brand rendering of Keyiyun. "Baifukeji" is another domain/brand used for the same corporate materials and product descriptions. Chuangwuzhe Artificial Intelligence is a subsidiary and R&D arm within the group, focusing on digital human technologies. Across all names and domains, the company markets the same set of products and capabilities—three-second voice cloning, thirty-second portrait cloning, lip-syncing, realistic digital humans, AI short video production via Ronghuike AI (ronghuike.cn), global multi-language support, NexFusionAi platform, private domain operation systems, and AI-based marketing and customer acquisition—serving industries from e-commerce and finance to cultural tourism, under an “AI + industry” strategy with over 200 proprietary IP rights.
NexFusionAi is an internal product of Keyiyun Group, described as its “global AI short video platform” and positioned alongside tools like Ronghuike AI within the company’s AI marketing and content ecosystem. Aimed at global markets, it appears designed for multi-language, multi-scene short video production to support cross-border e-commerce, international marketing, and brand localization. While often mentioned with features such as voice cloning, image cloning, lip-syncing, AI editing, and automated subtitles, it has no standalone website or public app, and is likely accessible only to Keyiyun’s enterprise clients through the group’s main online portals.
("Kexiyun" is most likely a misspelling or mistransliteration of the correct name "Keyiyun" (Kayi Cloud), not an official variant.)
