Tool overview
ZEGO Digital Human (JiZhi) is an AI video-generation application by ZEGO, featuring 2D/3D avatar customization, short-video creation, and digital-human live streaming. Users can upload 5–10 minutes of real-person video for 1:1 face and voice cloning, with a personalized digital twin delivered within 7 business days. Alternatively, preset avatars can be driven by text or audio to produce multilingual spoken videos. In large online classrooms, its AI Agent can power a digital-human instructor to give one-on-one practice feedback to each student.
It allows 24/7 operation, drastically reducing the cost of human hosts, studios, and equipment. A published case showed live-streaming cost reductions exceeding 50%. Multilingual support and batch generation make it suitable for high-frequency content demands. The underlying multi-modal AI combines visual perception, audio generation, and NLP for real-time interaction.
As for limitations, custom avatars require suitable source footage and about seven business days for delivery; the digital human’s responses rely mainly on scripted content, limiting spontaneous interaction. Pricing details are not publicly disclosed.
