No app installation is needed. SeedanceVideo runs entirely in the browser on any device — Windows, Mac, Linux, Chromebook, iPad, or phone. Your video is generated on cloud servers and downloaded as a standard MP4 file.

Why Use an Online AI Video Generator?

No GPU required. Local video generation tools (Stable Video Diffusion, CogVideoX) require an NVIDIA GPU with 8-24GB VRAM. Online generators process everything on cloud servers, making AI video accessible from any device.

Always up to date. Online platforms update models automatically. When Seedance 2.0 or Sora 2 receives improvements, they are available immediately without downloading updates.

Cross-device access. Start a generation on your desktop, check progress on your phone, download on your tablet. Your generation history syncs across all devices.
