[ Press release]Sandoll and ESTsoft Collaborate on Generative AI-Based Video Business

31 Jul 2025


  • Integration optimized for AI human videos and multilingual dubbing, creating an all-in-one production environment for creators
  • Joint development of generative AI-based font recommendation and creation technology to strengthen technical collaboration


On July 31, a strategic business agreement (MOU) was signed between Sandoll, a content creator platform company, and ESTsoft, a leading AI services company. The signing ceremony was held at ESTsoft’s headquarters, attended by key figures including Yun Young-ho, CEO of Sandoll, and Jung Sang-won, CEO of ESTsoft.


Through this partnership, Sandoll aims to incorporate generative AI and video/dubbing technologies into its stable subscription-based font platform, “Sandoll Cloud,” to secure new growth drivers. This move will allow Sandoll to enter the rapidly growing AI content production market and diversify its business portfolio, thereby enhancing its long-term growth potential.


A key element of this collaboration is the integration of ESTsoft’s AI video dubbing service, PERSO.ai, with Sandoll’s subscription-based font platform, Sandoll Cloud. This integration allows users to conduct AI-based multilingual video dubbing and create subtitles using professional fonts—all within the Sandoll Cloud platform, without the need for additional external programs.


PERSO.ai, a SaaS-based AI human and multilingual video creation platform developed by ESTsoft, can automatically generate videos in 110 languages, complete with AI humans, using only text input. It is widely used for various formats including short-form content, educational videos, and corporate promotional videos, with about 80% of its users coming from overseas—a sign of rapidly expanding global demand.


Sandoll recently partnered with LG CNS to integrate AI image generation web editor technology into Sandoll Cloud. This tool uses generative AI to automatically complete prompts based on a few keywords, producing high-quality images even for users with no prior content creation experience.


By consolidating ESTsoft’s AI video dubbing technology and LG CNS’s image generation tools into the Sandoll Cloud platform, Sandoll aims to provide an end-to-end AI-based content production hub. Customers will be able to produce subtitles, select fonts, and create videos and images—all in one integrated environment—simply by inputting text. This will significantly streamline the content creation process and enhance Sandoll’s service competitiveness and scalability.


Beyond basic integration, Sandoll and ESTsoft will collaborate on joint research and development to further improve user experience. Together, they plan to develop:

  • An AI font recommendation system that automatically suggests fonts suited to the mood of the video or image
  • An AI font generation technology that creates new fonts tailored to specific content styles


Jung Sang-won, CEO of ESTsoft, stated, “The combination of PERSO.ai’s innovative AI technologies and Sandoll’s design expertise will bring new value to the content market. We will continue to explore various strategies to enhance PERSO.ai’s competitiveness in the global arena.”


Sandoll CEO Yun Young-ho added, “AI-driven content production is already a key competitive factor in the global market. Through this partnership, Sandoll intends to evolve beyond fonts and become a comprehensive AI-powered content platform, serving as a practical partner for creators worldwide.”
