The process of training data and rendering photos using AI requires high computation from our server, if there are similar services or apps that sell at a price below what K-Beauty offers or even for free, you should be careful because the photos or personal data uploaded and inside the free app could be used by the app provider for commercial purposes. In addition, the quality of the photo results may not be as good as K-Beauty because the technology used in K-Beauty is continuously developed and improved.
