Bridging Technology and Culture with AI
Founded by experienced AI professionals and entrepreneurs, YESAI bridges the gap between technical excellence and real-world business needs. We’ve developed proprietary large language models and image generation systems designed specifically for CJK languages—overcoming the limitations of traditional English-centric AI.
Our Mission
We build AI that bridges technology and culture. YESAI develops systems that understand and create in Chinese, Japanese, and Korean, helping businesses and communities connect and communicate more effectively.

Our History
Founded in 2025, YESAI began as a small R&D lab focused on Korean language processing. We expanded to Chinese and Japanese, eventually building a unified multimodal AI platform. Today, we operate in Seoul, Korea, delivering innovative solutions across industries like education, media, and finance.
