Youyan is a 3D digital-human video platform for organizations and content creators, bringing script preparation, visual generation, and post-production into one environment. A project can begin with text, a presentation, or a PDF, which the system turns into an editable digital-human video with synthesized speech and presentation content. It is designed for teams that need explainers, demonstrations, or presentations without arranging an on-camera presenter.
The platform supplies 3D virtual characters and can generate scene composition, lighting, animation, camera movement, and individual shots around the submitted material. Generated work can then move through shot editing and visual packaging within the same production flow. Access requires signing in and accepting the service agreements, with the official login page offering QR-code and alternative sign-in methods.
